Product description
Design:
- the flute is composed of 4 grooves, this allows the high drilling speed and speeds up the removal of the drilled dust
- the drill bit head is fitted with X-shaped carbide and has one main and two additional cutting edges
Advantages:
- 4 cutting edges drill the hole of the exactly given diameter, thanks to reduced vibrations there is no unwanted elliptical shape and the comfort of the operator is increased
- the dense flute guides the core of the drill very precisely and this prevents it from oscillating
- the combination of the high-quality design of the X-shaped head and the dense flute ensures a smooth drainage of the drilled dust, therefore the drill bit does not heat up and this prolongs its service life
- the polished and smooth surface also helps to reduce the drilling resistance
Designed for: medium and large electropneumatic hammers in the weight category from 5 kg.
Caution: while drilling to a depth more than 400 mm, we recommend first pre-drilling with a shorter drill bit of the same diameter.
