Power
Saw motor power in watts. For petrol tools (see "Power Source"), horsepower is additionally indicated, see below for details.
The higher the power, the better the tool is suitable for voluminous work and hard materials, the greater the depth of cut it can provide and the easier it can cope with significant loads. In addition, for different types of saws and different types of materials, the actual power values \u200b\u200bcan also be different. For example, a power of
2.5 – 3 kW is actually the limit for
chain saws, but in
chain saws this is an average figure, among such tools there are models of
3 – 4 kW and even
more. Detailed selection recommendations for various cases can be found in special sources.
Bar/blade size
The largest tyre size (in chain saws) or disc (in circular saws and some others, see "Device") that is allowed for this tool. Tyres are sized by working length, rims by diameter.
A larger bar/wheel allows for deeper cuts but requires more powerful motors. Therefore, this parameter cannot be exceeded — this can lead to an overload of the engine with all the corresponding troubles. However, in many models with a disc it is physically impossible to install a nozzle with a diameter larger than the maximum allowable.
Also note that saws with similar bar/blade sizes may differ in maximum depth of cut (mostly due to differences in design or power). As for the specific dimensions, they depend on the type of saw (see "Device"). For example, large discs of
450 – 500 mm are found exclusively in stationary chain saws, the maximum figure for cutting models is
400 – 450 mm, for trimming —
300 – 350 mm, and sizes of
500 – 550 mm or
more clearly indicate that speech It's about a chainsaw chainsaw bar. Detailed recommendations regarding the choice of a tool for a given size can be found in special sources.
Cutting depth
The greatest depth of cut provided by the saw.
In most types of saws (see “Device”), the depth of cut directly depends on both the engine power and the size of the tyre / disk. The specifications give a value for the maximum allowable size of the working nozzle; when using nozzles of a smaller size, the depth of cut, respectively, will be less. But in band saws, this depth is rather weakly related to the actual length of the tape — it is determined primarily by the length of the open section of the tape, which is directly involved in the work.
Anyway, the greater depth of cut makes the tool more versatile, but comes at the cost of weight, price, and electricity/fuel consumption. So when choosing, it is worth considering the real features of the planned work and the dimensions of the workpieces that are planned to be cut. As for specific values, the most modest tools provide a depth
of up to 50 mm ;
50 – 75 mm is considered a low indicator,
75 – 100 mm is average,
100 – 125 mm is above average,
125 – 150 mm is already quite an impressive thickness, and the most powerful modern saws can have a cutting depth
of more than 150 mm.
Cutting depth (45° angle)
Maximum cutting depth achieved when sawing at a 45° bevel.
This feature is indicated only for those models that are originally designed for sawing at an angle — for example, due to the special design of the attachment for the blade / blade (in stationary models, see "Type") or due to the inclined support platform (in manual) . The maximum angle of inclination of the saw in such models can be different (see below for more details), however, 45 ° is considered the standard option, so it is for this inclination that data on the depth of cut is given.
The general meaning of this parameter is quite obvious. On the one hand, a greater depth of cut allows you to cope with thicker workpieces and generally gives you more options; on the other hand, an increase in depth requires an increase in the size of the disk / canvas and an increase in power, which, accordingly, affects the price, dimensions and consumption of electricity / fuel.
Cutting width
The kerf width determines the maximum size of the cutting line, and therefore the maximum width of the workpiece that the saw can cut through in one go. The value of the kerf width depends primarily on the diameter of the saw blade. Additionally, the stroke of the broach mechanism should also be taken into account. Saws with a pulling mechanism provide a cut that exceeds the diameter of the cutting blade.
Number of speeds
The number of operating speeds provided in the tool. Specified only if there
are more than one velocities. The larger this number, the more settings the user has at his disposal, the more extensive the possibilities for setting the operating mode for a particular situation.
Note that in some models, instead of several speeds, a smooth adjustment of the number of revolutions may be provided (see "Functions —
preset revolutions ").
Saw angle
The maximum angle at which the working part of the saw can be tilted relative to the vertical. It can be indicated not only for stationary tools, but also for manual ones — in the event that the design provides for a support platform. It is worth paying attention to this parameter if you have to deal with oblique cuts: making such cuts by setting the saw to a certain angle is much more convenient than adjusting this angle manually.
Saw angle
The largest angle at which the working part of the saw can be rotated relative to the standard position (note that we are not talking about tilt, but about turning from side to side). This feature is often found in miter saws (see Device) which are not limited to straight cuts; turning the saw is the most convenient, and sometimes the only way to cut the workpiece obliquely.
In box
- Disc. The presence of a saw blade is included in the delivery set of the circular tool. It can be either one or
several, which allows you to use the saw “out of the box” without the need to purchase additional consumables. If you already have a saw blade or intend to select it for specific tasks, it is worth taking a closer look at the configurations
without a blade - they are usually cheaper.
- Chain. One or
more chains included as standard with the saw. The presence of a chain with teeth for cutting allows you to do without purchasing a separate executive body for chain saw. However, there are configurations
without a chain - it is assumed that the customer already has a chain or he will select the required option himself.
— Saw blade. The presence of one or
more saw blades in the complete set of a reciprocating or band tool. They ensure that the saw is ready for use literally immediately after unpacking. There are also configurations of reciprocating or band models
without a saw blade - they are cheaper, and the customer has the right to choose a suitable blade independently.
—
Dust collector. A dust collector is included with the saw. The dust collector is a container for collecting sawdust and other d
...ebris generated during operation; As a rule, such a container is made removable. Installing a dust collector slightly increases the dimensions of the entire tool, but this is compensated by cleanliness and convenience: dust and other production waste mostly settle in the container and not on surrounding objects.
- Charger. The presence of a charging block in the package allows you to charge batteries. Accordingly, for models with batteries, this accessory is necessary to power the battery. However, there are models without a charger. And saw with it may differ in the charger model, the name of which will allow you to learn more about its characteristics and, if necessary or if required (breakdown), purchase a similar one.
— Case (bag). Availability of a case or bag included with the instrument. A case is a container-suitcase made of hard material; bags are usually made of soft material. This way the case provides maximum protection and the bag can be folded away compactly when not in use. The specific type of case that comes with the saw should be specified separately. However, in any case, a complete case or bag will be more convenient for storing and transporting the instrument than impromptu packaging.
- Stand. The stand makes the saw tool more stable, reliable and safe. The presence of a stand is typical for stationary type saw. Mostly these are powerful, productive, large and heavy models that are located in a separate place. The stand can be implemented either with classic legs (bed) or with a cabinet with a tool compartment. The stand can be equipped with various types of saw: circular saw, miter saw, band saw, cutting saw and even chain saw (with electric drive).
— Wheels for transportation. Transport wheels make it easy to move sawing equipment around the shop. The presence of wheels will come in handy when the saw needs to be moved a little to install some large workpieces or simply when cleaning the workshop. As a rule, wheels are typical for stationary saw with a table top or work holder.
