Plunge Saw What Is Needed For

Bow Saw For a bow saw for wood, it does not matter whether the wood is cut along or across the grain. If we add to this the possibility of working with one hand (the first “rays” were exclusively two-handed), it turns out that the tool in question can be used to cut a tree:

What is a bow saw for?

It is convenient to make short, mainly transverse cuts with a jigsaw, long, longitudinal cuts with a hacksaw on wood. And only with the help of a bow saw can a variety of dividing cuts be made, both with dry and damp wood. In addition, for a bow saw for wood, it does not matter how the wood is cut. Along or across the fibers. If we add to this the possibility of working with one hand (the first “rays” were exclusively two-handed), it turns out that the tool in question can be used to cut a tree:

  • Longitudinal;
  • In the transverse;
  • In curly;
  • In the angular direction.

The only insurmountable obstacle for bow saws is the transverse dimensions of the workpieces. For thick logs, it is still better to use a power tool. However, you have to work with thick logs much less often.

Three circumstances give the versatility of bow saws for wood:

  1. Adjustable saw blade tension (in some ways, this process is similar to pulling the bowstring of a bow, hence the name of the tool). Testing shows that in bow saws, tensile forces of up to 100. 120 kg can be created without breaking the saw blade.
  2. The special shape of the teeth allows for both roughing and finishing cuts.
  3. Compact dimensions of the saw, which ensures its use even in confined spaces.

Modern manufacturers of bow saws and accessories for them. The brands Bahco, Stanley, Intertool, Fiskars and others. Complete their products with different types and designs of saw blades, which increases the ease of use of the tool.

Bow saw. Combination of reliability and versatility

Bow saws have long held a place of honor among carpentry tools. And although their construction and design have changed significantly over the years, the basic principle of operation of these saws remains the same. What is the advantage of this tool and what makes it stand out from the rest?

The modern “onion” includes:

  1. Frame made of profile rolled products. Depending on the size of the saw blade. And they are usually standard: 350 mm, 530 mm or 760 mm, the frame can be made in the form of a coated trapezoid (for longer blades) or a coated triangle (for shorter ones).
  2. A handle with a profile that prevents sudden injury to the worker’s fingers.
  3. Saw blade.
  4. Saw blade tensioning devices.
  5. Fastening the canvas to the frame.

Special requirements are imposed on the frame of a bow saw for wood. It must be rigid and at the same time light, so as not to increase physical activity during sawing. This task is met by a special tubular profile with a very small width. This makes it easy to bend it in the manufacturing process to the required frame configuration, without losing the strength of the part, providing the saw with the necessary mobility.

One of the main differences in the design of modern bow saws for wood is the principle of the saw blade tension. For example, the Gardena or Proline brands use an eccentric handle for tensioning: by changing the angle of the handle with respect to the longitudinal axis of the saw, this way you can adjust the tension force.

Manufacturers of saws from Bahco Stanley took a different path: a special screw mechanism for tensioning the saw blade is mounted in the handle. The choice is determined by the convenience of use, however, the presence of a screw mechanism provides increased tension in the tension, and does not depend on the random movements of the user, when the position of the handle during sawing can randomly change. Therefore, the pivot tensioner is recommended if you have some experience with a bow saw.

Removable cotter pins or thumbscrews are used to fasten the saw blade to the opposite part of the “bowstring” (frame). The latter are more reliable, since the cotter pin, usually made of mild steel, wears out over time and can spontaneously come out of the mounting hole.

Plunge saw what you need

The plunge-cut saw is a popular type of power tool and is used when sawing wood. What are the characteristics of guide rail disc models? What to consider when choosing a unit?


For comfortable work. The plunge-cut saw blade is located above the sole and is completely covered by a protective cover. All controls are located compactly, so it is convenient to work with the tool. Compared to conventional circulars, submersibles look bulky, but they are ideal for joinery work.

Benefits of submersible circulars

  • Precise sawing of openings. A regular circular can also cope with this task, but an immersion will make everything more accurate. On the sole, it has pillars that allow you to accurately position the saw (the disc will cut strictly along the mowing line marking). Another rear sight is applied opposite the cutting edge of the tooling. Focusing on it, you stop the saw at the intended point, leaving no sawing marks outside the opening.
  • Can be cut close to the wall. This is possible due to the fact that the disc at the submersible circular is located on the side of the sole.

Plunge-cut circular saws

Submersible circulars are expensive and are found in the catalogs of only a few well-known manufacturers. But among the pros, the interest in this tool is great. What are its advantages over a conventional circular?

Makita plunge-cut saws: masters of tapping

Plunge-cut saws are a type of circular saw. They are designed for longitudinal and cross-cutting of massive wooden blanks and for cutting sheet materials (plywood, chipboard, etc.). With the appropriate saw blades, this saw can also handle plastics, metals and laminates with ease. That is, the functionality of the species and subspecies is similar, however, in some cases, it is without a plunge saw, as without hands.

For what

A special feature of such a saw is a special plunge-cut mechanism that allows you to accurately and quickly cut into the workpiece anywhere, and not just from the edge, as is possible with conventional circular saws.

By the quality of the cut. Purity and accuracy. Makita plunge-cut saw when cutting sheet materials is quite capable of replacing a table sawing machine. It can be used to cut grooves, gutters, slots on vertical, horizontal and inclined surfaces. Embed a sink and a hob into the countertop without any problems, or repair the floor with partial removal of rotten elements. A plunge-cut saw will come in handy in a cramped workshop when working with bulky workpieces, when there is no way to come up from the end to “cut” with a regular circular. Makita plunge-cut saws allow you to cut in close proximity to any stop. For example, along a wall at a distance of only 18 mm from it. Such a saw is also in demand during the installation and repair of the roof. It will be used by workers of various specialties. From cabinetmakers to carpenters.

Principle of operation

The external distinguishing feature of plunge-cut saws is the height and shape of the upper guard and the absence of the lower one. This is because the saw blade is fully positioned at the top and is lowered to the working position only when the tool is switched on. At the same time, the disk gradually picks up speed and confidently cuts into the workpiece in strict accordance with the marking.

The depth of cut in Makita plunge-cut saws is adjustable with an accuracy of 1 mm and is securely held in place by robust clamping mechanisms. In order to avoid chipping when cutting delicate materials, such as laminate flooring, it is recommended to pre-cut to a depth of 2 mm, which is quite possible with the adjustment system available in the presented plunge-cut saws from the Japanese manufacturer.

High cutting accuracy is ensured by using a fusing bar, which can be supplied as a set (Makita SP 6000 SET) or purchased separately. At the same time, the use of the bus eliminates the need for detailed marking, which greatly simplifies the process and saves working time.

For coarse cuts plunge-cut saws can also be used without guides: there is a small notch in the sole to follow the mowing line. They are also applicable with a parallel stop, but we repeat that high cutting accuracy is achievable only with a guide rail.

Plunge-cut saws can also “fill” the edge of the workpiece. Make a cut at an angle. The standard cutting angle is 45º, in some models it is increased to 48º (Makita SP 6000).

Electronic components

In terms of electronics, Makita plunge-cut saws are complete. Intelligent systems regulate and stabilize the speed, control the temperature on the windings, are responsible for smooth start-up and eliminate shock loads on the mechanism. The speed of rotation of the disk at idle speed is regulated in a wide range, which allows you to choose the most suitable mode for high-quality work on various materials.

Thus, we can state that Makita plunge-cut saws are equipped with all the functions necessary for comfortable work and achieving excellent results. In addition, the mechanism protected by electronics is characterized by increased reliability and durability.

Ergonomics and safety

Due to their design features, Makita plunge-cut saws are practically the safest, if this definition applies to saws in general.

The ravenous disc teeth are protected by a robust die-cast aluminum casing. The mechanical engine brake ensures that when the tool is turned off, they stop immediately. This will take just a couple of seconds, and the safety clutch will exclude a kickback when the cutting blade is jammed.

Double insulation of live parts significantly reduces the risk of electrical injury. For the same purpose, the power cord is positioned in such a way as to prevent accidental damage.

To avoid unintentional start-up, Makita plunge-cut saws are equipped with an anti-start system. For trouble-free change of working discs, the possibility of fixing the spindle is provided.

Lightweight and compact saws are equipped with comfortable handles covered with high-quality elastomer. They fit comfortably in the palm of your hand and do not slip, which is important for maximum control over the instrument. Especially when working intensively.

No harm to health

As you know, during the sawing process, a large amount of sawdust and fine wood dust (when working on wood) is formed, which impair the view of the mowing line of the cut, which reduces the quality, and is also very harmful to the user’s health. In order to eliminate all these factors, the Japanese developers have equipped their plunge saws with an effective dust extraction system that can be connected to a Makita industrial vacuum cleaner. For this, there is a built-in connection at the rear of the protective cover.

As practice shows, Makita plunge-cut saws are very practical and are in demand in the domestic market for several reasons. Of course, the fundamental of them is the high quality of the instrument and its indicative reliability at an affordable price. So a similar Festulov machine costs twice as much, although the quality of the work performed does not surpass Makita at all.

Makita plunge-cut saws are equipped with a carbide blade for high cutting quality. The blade itself is characterized by a long service life without compromising cutting performance. At least, according to the testimony of one of the happy owners of the Makita SP 6000, after a 200-meter marathon on chipboard, the cleanliness of the cut remained unchanged.

According to him, all functions work clearly and in a timely manner: in particular, when the disk jammed, the engine was instantly braked, which made it possible to avoid a kickback.

The saw glides smoothly on the bar. No backlash is observed. As a guide bar, you can use both the native Makita P-39534 (the range is not great here), and tires from other manufacturers.

The native tire fits snugly on the surface to be cut and remains stationary thanks to the rubber pads, the weight of the tool and some pressure from the user. On inclined surfaces, the tires are fixed with clamps.
