Brickwork drilled through quickly - flexible in depth and diameter.
Highest drilling performance and long lifetime thanks to high-alloy special steel
Fast progress even in hard concrete
aerated & porous concrete
sand lime brick
Hammer drilling in concrete, sand-lime brick, natural stone, brickwork, clinker.
The special technique of hardening by blasting makes for the perfect surface finish: the probability that a Heller hammer bit will break under very high loads is extremely low – even on impact with reinforcements. Ideal, especially with long dimensions: HST hardening guarantees high bending flexibility without breaking.
