Real power

The power delivered by the tool motor directly to the cutter or blade. The output power is inevitably less than the power input of the motor.

Note that in the characteristics of tools this parameter is given relatively rarely. However, it is he who most accurately describes the general capabilities of the unit, such as speed, the ability to make deep cuts and cope with hard materials. Therefore, it is best to compare different models with each other precisely in terms of output power.

This indicator also allows you to evaluate the overall efficiency: the higher the ratio of output power to the power consumption of the engine, the more efficiently the tool consumes energy / fuel.

Disc/cutter size

The diameter of the blade/cutter for which the tool is designed.

A larger blade can provide greater depth of cut, but requires a more powerful motor. Accordingly, this parameter is directly related to the power and performance of the tool: the more powerful and heavier the unit, the usually larger the diameter of the working element in it. Note that some models allow the installation of cutters / discs and a smaller diameter than the standard one, but you cannot install a larger work item.

Rotation speed

The maximum speed of rotation of the disk / cutter provided by the tool.

The higher the speed, the higher the speed of the cutting edge relative to the material, the higher the processing speed and the more accurate the cut is. On the other hand, as the speed increases, the torque decreases. So for the same blade/cutter diameter, higher RPMs will be beneficial on relatively soft materials, while a slower tool will be better for hard and stubborn materials.

Processing depth

The depth to which the tool can cut through the material. This characteristic is directly related to the diameter of the blade / cutter (see above) — for greater depth, a larger diameter is required. However, units with the same working element size may differ in the depth of processing due to the difference in engine power and some design features.

In many models, the depth can be adjusted; for such devices, the minimum and maximum depth values \u200b\u200bare indicated in the characteristics.

Water tank capacity

The volume of the water tank installed in the floor cutter (see "Device").

Water from the tank during operation is supplied to the cutting zone to cool the blade / cutter and the material being processed. The larger the tank, the less often you will have to refill it, but the more “extra” weight you will have to carry with you when working. Therefore, this parameter is selected by manufacturers for the specific features of the joint cutter: the more powerful the tool, the more water it needs and the larger the tank.

Engine size

The working volume of the internal combustion engine (see "Type") installed in the joint cutter.

A larger volume, usually, gives more power, but there is no strict dependence here. Therefore, when choosing, it is better to focus not so much on volume as on the claimed engine power (see below).

Power

The power of the internal combustion engine (see "Type") installed in the floor saw. For internal combustion engines, power is traditionally indicated in horsepower; 1 HP ≈ 735 W.

The higher the power, the more force the tool puts out on the blade / cutter, the better it handles with hard materials and the larger the size of the blade / cutter can be (which, in turn, increases the depth of cut). On the other hand, powerful engines have high cost, high weight and high fuel consumption. Detailed recommendations on choosing the power of a joint cutter for a specific situation can be found in special sources. Also note here that when comparing according to this indicator, it is worth considering the presence of a self-propelled structure (see "Functions" / "Additionally") — in self-propelled units, part of the power is spent on movement.

Fuel tank capacity

The volume of the fuel tank installed in the floor saw with an internal combustion engine (see "Type"). Knowing the capacity of the tank and fuel consumption, it is possible to estimate how long a full refueling will last.
