Nutrition

The power tool can be powered by either a mains or a battery.The advantages and disadvantages of the two types of nutrition are obvious.

Power

The amount of electricity required to complete the job.It affects the productivity, speed of individual operations, etc. Machinery and equipment with high power allows you to work longer and more intensively without interruptions and stops.

Cartridge

The type of chuck is determined by the type of tool shank used in the tool.

Cam chucks are simpler and cheaper, allow you to clamp the shanks of various shapes and sizes, but require a lot of time for the operation.

Keyless chuck is also universal, as well as cam, differs from it by the absence of a key.

Collet chucks are available in two main standards - SDS-Plus and SDS-Max.The tool with the SDS-plus chuck is lightweight, versatile and lightweight.The equipment is easily replaced without the use of additional tools.The tool with the SDS-max chuck has more power, allows you to use equipment with a larger diameter.

Hexagonal chuck - the strongest and most reliable, designed to fix the hexagonal shank of shock equipment.Such a cartridge is usually equipped with industrial impact hammers with high impact energy.

Beat frequency

The beat frequency indicates the maximum number of beats per minute and affects the level of vibration (or the degree of impact).

Impact energy

Maximum impact force is one of the most important characteristics of a perforator and jackhammer, on which the productivity of the tool depends.The lower this indicator, the less material the tool can “beat off” in one stroke.In addition, models with a higher maximum impact force are usually heavier.

To remove tiles, plaster, hardened cement mortar residues, laying channels for wiring, the impact force should reach 2.5 J.

When destroying materials of medium strength (brick, cement compounds with a large proportion of sand and clay) - 2.5-3.6 J .

For chipping durable concrete and dense stone requires the force of impact rocks from 3.6 to 5 Joules.

Dismantling of a large number of concrete slabs, metal felling, chiselling of frozen soil and rocks should be carried out with an impact force of more than 5 J.

Reverse - rotation of the tool in the opposite direction.It is used, for example, for use as a screwdriver.

Usually, punchers are equipped with a safety clutch, which serves to stop the rotation of the chuck when the tool is jammed in the hole.This condition is fraught with a breakdown of the nozzle or punch and injury to the worker due to a sharp jerk of the tool that occurs when the drill stops immediately.The safety clutch protects the tool motor from overloads.

Angle drill

The ability to lock the power button during long operations.

Factory delivery kit.

The company case allows you to neatly and compactly store tools and accessories.

Drills included in the kit.

Chisel (peak) - a tool for cutting various materials.

Bits - short screwdriver bits.

The bit holder allows you to set various bits in the instrument.As a rule, the magnetic principle of fixation is used.

Width

The width of the device in millimeters.

Weight

The weight of the device.
