7 Best Handheld Circular Saws for Home Use

A huge assortment of circular electric saws baffles the home craftsman. Let's try to simplify the task of choosing the right tool. You have to find the optimal combination of power, weight, capabilities and price. It is preferable to “dance from the stove”, i.e. start from the tasks, and specifically, from the greatest thickness of the material being cut. From here the main characteristic is selected - the maximum cutting depth, which should exceed the thickness of the workpiece (or half the thickness) by at least a few mm.

Main areas of application:

Finishing non-carpentry work: cutting sheet materials (laminate, chipboard, OSB, plywood) and non-thin boards (platbands, lining, block house, parquet).
Carpentry construction work: transverse and longitudinal sawing of boards and timber up to one hundred mm.
Heavy work (building a house from timber, collecting firewood): transverse and longitudinal sawing of timber and logs one hundred to two hundred mm thick

In the presented review, we will first pay attention to the first and not the third point.

Best lightweight circular saw for thin material

Among the few good electric saws weighing up to 2.4.5 kg at a reasonable price, there is little competition. Interesting are Bosch PKS forty (3500 rubles), RYOBI RWSL1801M (3200 rubles) and sell Skil five thousand seven hundred and forty CA (2200 rubles). Despite the fact that the Skil company is considered the creator of this class of tools, now they are definitely inferior to their “big brother” Bosch. RYOBI looks good, unfortunately the owner of this brand, TIC (Hong Kong), has not yet established proper service with us.

Bosch PKS 40 fits perfectly in the hand, allowing you to easily work not only on a workbench, but also in inconvenient places if desired. Six hundred watts is enough to cut a dry pine board up to thirty mm with a one hundred and thirty mm disc, automatically. If the material is harder or thicker, then you cannot rush the feed movement so as not to overload the motor. You have to cut a “magpie” board lengthwise on both sides.
Reviews of the Bosch PKS 40 circular saw:

How exactly saw up board circular saw.

Bought circular saw. It turned out that to nag(even transversely), it’s not that simple, the mark ends, and the boards.
“There is nothing superfluous, and everything that is there is done carefully and with high quality. So, for example, the bed, although stamped and not cast, reliably holds the tool in a given position.”
“The complete blade, despite the small number of teeth, cuts cleaner than I expected. Its main advantage is that it is small and light.”
Saw satisfies the requirements of the first point and receives the highest score – 10.0

The best heavy-duty circular saw for heavy-duty jobs

Work according to claim 3 is rarely found among non-professionals. The supply of relevant tools is also small. You can pay attention to two models from Makita and one from Hitachi. However Makitovskaya 5103R(18 zero rubles, 9.4 kg) has a maximum cutting depth of exactly one hundred mm, which is not entirely good. 5143R with a cutting depth of one hundred and thirty mm is a bit heavy for both the hands and the budget - 14.5 kg and almost thirty,000 rubles. And not everyone can wield it circular saw weight.

And here Hitachi C13U, perhaps just right. A disk with a diameter of three hundred thirty-five mm, spun up to 3400 rpm, bites to a depth of one hundred thirty-eight mm. The weight and price are considerable, but quite reasonable - thirteen kg and fifteen,000 rubles. Two kW of motor for such a disc is not a lot of power, so the instruction manual rightly warns against trying to speed up sawing by pressing hard forward.
For heaviness Hitachi C13U deduct 0.5 points. Rating – 9.5.

Professionals have a separate saw for each of the points, but for a home craftsman this is too wasteful, so the optimal choice for most is a saw suitable for work according to points 1 and 2. Therefore, among such saws, we will consider five models, each of which has its own advantages.
Our choice of manufacturers is based on the ratio of price and number of positive reviews. Of course, instruments made by Maffel, Protool/Festool or Hilti are very good, but the price tag with the cost of a tour to Egypt (sometimes for two!) is unlikely to win the approval of your wife. We also don’t consider tools with distinctly Russian names, which our southeastern neighbors offer us for the price of an ordinary hacksaw made of good metal. Although some masters take them “on the same scale.”

After analyzing manufacturers' websites and feedback from craftsmen's forums, we selected five nominees and tried to rank them using objective characteristics. In terms of ergonomics, first place was given five points, and last place – 1. Main technical characteristics and average prices according to Yandex. Market" are tabulated.

To manufacture various structural elements of a bathhouse, you will need not only the ability to properly cut a log, be able to chop or extend it, but also saw various wooden parts - boards, bars.

Depending on the situation, sawing can be done along the wood fibers or across it. To ensure a fairly even cut, it is advisable to securely secure the material in a clamp.

The cutting line is preliminarily marked by marking and only after that the cutting begins.

If the material being cut is securely fixed in a horizontal position, then saw while holding the saw with both hands. If the material is not secured too securely or is located vertically, then saw with your right hand and hold the material with your left.

The marked marking line should always be to the left of the cut.

If you need to cut a board or block at an angle, it is convenient to use a special device in the form of a box with guide grooves in the walls. This device is called a miter box.

You can make a miter box yourself. To do this, it is enough to connect three strong boards so that one serves as the base, and the other two act as side walls with cuts made in them, as shown in the figure below.

Miter boxes of various types are offered today by a variety of manufacturers of construction tools. The photo below shows the Stayer miter box.

Depending on the thickness of the material being cut, the angle of inclination of the saw blade to the plane of the material is selected. The thinner the material, the more acute the angle the cutting edge of the hacksaw blade should form to the plane of the material being cut and vice versa.

For cutting along a curved line, special circular saws are used. A circular saw is distinguished by a narrow blade and such sharpening of the teeth that it allows cutting along complex curved lines, which is almost impossible to do with a conventional hacksaw.

To cut a large number of boards, it is more convenient to use modern hand-held electric and chainsaws. This saw does not require significant physical effort and allows you to quickly make an even cut.

You can see how to use a chainsaw in the video below:

Tools

When cutting various materials and making blanks for building structures, an even cut is necessary. On an industrial scale, this is achieved using large professional machines. But how to achieve an even cut using hand tools?

The most suitable tool for smooth cutting is a circular saw. For precision cutting, circular saws are equipped with special grooves that are located on the soles of the saw. As a rule, these are two grooves (notches), one for cutting workpieces at an angle of 90 degrees, and the second at an angle of 45 degrees.

After we have marked the cutting line, we place the slot on the line and run the saw along the marked line. In order to prevent sawdust from getting on the cutting line, in many saws the air flow from the electric motor fan is directed to the slot.

It must be said that some models of saws have special lasers that are not interfered with by sawdust, so the laser beam falls on the workpiece from above. In addition, circular saws are equipped with a special stop, which has a ruler, thanks to which you can set the width of the workpiece and, relying on the smooth edge of the board, make an accurate cut.

When cutting boards crosswise, you can use special devices that can be adjusted to different angles. Some professional series saws are equipped with a special groove in the sole. This groove overlaps the guide rail. The saw slides along the bar and makes an even cut.

For simpler models, circular saws, it is best to use a flat blade. The rail needs to be secured to the board with two clamps. After this, resting on the rail with the edge of the circular saw sole will help you make a precise cut.

When making a homemade guide, you can use both improvised means made on commercial machines and aluminum rules. In this case, you can make a special stand with three bearings or stops, which can then be attached to the sole of the circular saw. The stops or bearings will slide smoothly according to the rule and this will be a guide for making an even cut. Author RVT

Wood, like natural stone, is one of the most ancient building materials. Despite the huge selection of various artificially created materials existing on the construction market today, timber is still very popular. In order to obtain high-quality lumber, the log must be cut into boards. In this article we will talk about how to cut a log into boards.

Types of log cutting

Sawing logs into boards is carried out in two main ways:

radial
tangential.

In addition, additional methods are possible:

mixed
semi-radial (rustic)
central.

Radial sawing is a type of sawing during which the axis of the cut runs through the core of the log and, as a result, the annual rings in the section of the board form an angle of 76 - 900. The lumber obtained by such a cut has a uniform color and texture. Timber almost does not undergo deformation during drying and does not swell when moistened, because the dimensions of the wood change mainly along the line of the rings (across the grain). In radial sawn timber, the annual rings are arranged according to thickness. Such materials are distinguished by the highest performance indicators in comparison with other types of lumber.

Tangential cutting is carried out along tangents to the lines of annual rings at a short distance from its core. The surfaces of the resulting boards are distinguished by a pronounced texture and a bright wave-like pattern of annual rings. Such lumber is characterized by higher coefficients of shrinkage and swelling from moisture compared to radial cut boards. As a result, they are greatly deformed when exposed to moisture. Such boards are in demand for use in dry conditions.

Rustic (semi-radial) and mixed types of cutting have characteristics of two main types of cutting simultaneously: radial and tangential. Therefore, they exhibit average shrinkage and swelling coefficients. Rustic cut boards are distinguished by straight lines of annual rings, which are located at angles of 46 - 75 degrees. to the layers. Mixed sawn timber is distinguished by the fact that the lines change from straight at the edges (along the width) of the board to arched towards the middle.

The center cut is made right in the center of the trunk and contains its core. Taking into account the fact that the core of the trunk is wood with the lowest strength indicators, center-cut lumber is characterized by a structure that is heterogeneous in strength.

Tools for sawing logs

Tools and cutting methods depend on the total volume of logs, such indicators as length and thickness. In addition, you need to take into account the quality of the future lumber. Cutting a log involves working with different tools and specialized equipment. In order to obtain a small amount of lumber at home, a manual method of processing logs using a chainsaw or traditional hand saws with teeth for longitudinal cutting is suitable.

The sawmill is perhaps the most famous type of sawmill equipment. This is a woodworking machine that contains frame saws. The sawmill produces longitudinal sawn timber, for example, edged boards or timber. Sawmills allow processing logs with a diameter of 15 to 80 cm and a length of up to 7 m.

Cutting logs into boards using circular saws (circular saws) is carried out using a circular saw. Such equipment can be single-saw (single-disc) and multi-saw (multi-disc). Devices containing one disk are suitable for working with small-sized and low-quality raw materials. Using multi-disc machines, you can cut round workpieces of large diameter.

Band sawmills are the most popular today. They come in two types: vertical and horizontal. The cutting tool in such equipment is a belt blade that is put on pulleys. Working on band saws guarantees the production of high-quality longitudinal and mixed lumber, such as boards and beams. This produces the least amount of waste.

Large industrial enterprises use wood sawing lines. They allow achieving very high surface quality and precise geometry of the final products. Such lines are characterized by the highest productivity.

In addition to all the equipment listed above, such types of highly specialized sawmill equipment as debarkers, edgers, band-dividers and other types of machines are also used.

Very often there are situations when you need to produce a very small volume of boards or beams for your own needs. Of course, buying machines in this case is absolutely not an option. Having certain knowledge and skills, it is much more profitable to cut logs with your own hands, using an electric or gasoline chain saw. Despite the fact that this work is quite labor-intensive, the result is quite justified.

Most experts believe that a chainsaw is better suited for this purpose. Such equipment has high power and can operate without interruption for a long time. In addition, the operation of a chainsaw does not require electricity, so you can work far from the power supply, for example, right on the plot.

In order to cut a log into boards using a chainsaw, you will also need special tools, such as a mechanism for securing the log, a frame attachment for the chainsaw, and a guide for making the cut. The attachment frame must be attached to the chainsaw bar so that it can be used to adjust the gap between it and the chain. This will make it possible to create boards of different thicknesses. It is worth purchasing a special chain for longitudinal sawing. It has a special tooth sharpening angle. The guide ruler can be made from a metal profile of the required length or a flat, rigid board.

Before starting work, you need to remove all the bark and remaining branches from the workpieces, and also carefully inspect the log for various flaws. This way, you can choose the most suitable cutting pattern and, therefore, reduce the amount of possible waste.

If you are longitudinally sawing trunks, you need to make sure that the resulting lumber is of the same density across the entire width. Since the density of wood from the northern part of the log is much higher than from the southern part, the cut is carried out in a plane directed from east to west (or in the reverse order).

The first step is to remove the slabs from two opposite edges of the log. As a result, a double-edged beam will be obtained, which is then cut into boards or other lumber of equal thickness, according to the intended sawing pattern. The final product is an unedged board, from which the edges must then be removed.

For many centuries, timber has been the most popular raw material for housing construction. Today, primitive processing methods have been replaced by modern equipment. For example, to cut timber and process it to the required size, craftsmen use a sawmill. The disadvantage of such a machine is the cost. For this reason, many people make mini sawmills based on chainsaws.

How to cut a board straight

Greetings to all readers who are not subscribers to my blog. How to work with a hand-held circular saw, how to cut a board straight along and... Now I, Andrey Noak, would like to talk about how to cut a board straight. Wood is actually considered the highest quality, non-environmentally friendly material for construction.

Introduction

Wood has found application in various industries. This raw material has always been popular due to its versatility and ease of extraction and processing. Furniture, interior items, and sometimes entire houses are made from wood.

Every master encounters this material, but, from the characteristics of practice, not everyone is able to carefully cut the board. After tools, chips often remain on the cut, also called jagged edges, which does not add beauty to your product. So which method is better? saw up in artisanal terms, in other words, order?

Some companies offer for purchase saw up Your boards, in addition, the cost for this service is slightly overpriced. In production, boards are cut by a qualified craftsman using precise equipment, which allows you to obtain high-quality workpieces of suitable size and shape.

Ladies like you, but you won’t be able to acquire expensive equipment yourself, but is there any point here, if necessary? saw up several boards. Choose only for you, if you decide to cut boards at home, then I will tell you how and how it is more convenient to do it.

What is the best way to make a cut?

Circular saw

This is a better tool for sawing boards. Comparable with certain principles of power tools, oil has greater productivity. As annoying as this may sound, it is worth keeping in mind that circular saws differ in features and not in the area of application.

While picking up the saw, decide for what purpose you will use it. The main use of circular saws is cutting or sawing boards.

When choosing saws you need to take into account the depth saw. There are circular saws on sale with cutting depths from thirty to one hundred and thirty mm. You need to find out what thickness of boards you will be sawing and, based on this, give preference to one saw or another.

It is also worth taking a responsible approach to choosing a blade for your circular saw. If you need to make a neat cut, you should choose a saw blade with a higher tooth frequency. If the teeth on the disk are sparsely spaced, the work will be faster, but much rougher. It is important that when working with a circular saw, the cuts are smooth and practically without chips. How to carefully cut a long board, how to cut a “window” in a piece with a circular saw. This is discussed in more detail in my book. More details about it in the “BOOKS” section.

When cutting boards with this tool, craftsmen advise placing a notched disk for a circular saw on it. Imagine that while working, the grinder caught a piece of wood in one of the notches, you immediately release the power button (those who worked with it know that after turning off the disk will make a few more revolutions) and it is not known where you will find your tool after that, on the floor a couple of meters away from you or in your body.

Or, for example, the disk got hot and burst, which is also quite possible; pieces of the hot cutting wheel scatter over the entire area, and some of them may land on you. Other craftsmen use a disk with a victorium solder, which can also easily end up in your foot.

Therefore, it is better not to take risks, but to use a tool specially adapted for this work.

Hacksaw

In order to make an even cut with a hacksaw, first you need to draw a cutting line with a pencil on the board, then position the workpiece so that it is convenient for you to work with it, and secure it in this position. The next step is to set the hacksaw at a position of approximately sixty degrees to the product, guide the saw with your thumb so that it runs exactly along the cutting line.

Start sawing as soon as your cut is so deep that saw you can calmly “walk” in it without straying from the mark, you can turn it to a position convenient for you, usually ninety degrees, and continue washing until you achieve the desired result. If the wood is damp and soft, the hacksaw teeth will get stuck in it, which will make the job more tedious and time-consuming.

To make your work easier, lubricate the tool with soap, which will make your task much easier. For a novice craftsman, the first cuts are not very even, so it's better to take advantage a block that will serve as a guide.

If you need to make a cut at an angle, use a miter box. It has pre-made grooves for a hacksaw. All you have to do is attach it to the workbench, place the part in a special groove and cut along the angle you need. The cut will be smooth, with virtually no chips.

To make it beautiful saw up boards it's better to take advantage with the help of a qualified craftsman, if you think that you are able to cope with this work yourself, then under no circumstances make cuts with a grinder, it's better to take advantage with a hacksaw. For neat cuts along boards, the best tool is a circular or disk one saw.

An important point in cutting boards is accuracy and precision; this is painstaking and labor-intensive work. The main thing is to never forget that any hand tool, and even more so a power tool, can cause harm to you, never neglect the safety rules, it’s better to be safe, because health is the most important thing.
