- Carbide teeth
Applications
- Strengthness and effi ciency for sanitary heavy work and renovation.
- For all type of drill hammers with power of more than 950W.
- Cone-shaped shank.
Advices
While using powerful (> 18 Joules) percussion hammer drills, one needs to:
- Avoid empty hammering (when only the centring bit is in the material, and not yet the core bit); that makes it necessary to pre-drill with the centring bit alone.
- When the core bit is assembled, lock it on the taper of the core bit adapter
- Always start drilling with the core bit using the centring bit positioned in the pre-drilled hole
- Remove the centring bit as soon as it is no longer necessary (i.e. as soon as the core bit comes into play)
Materials
- concrete, stone, brick, breeze block
