Perfectly designed for use with cordless machines.

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.

Percussion-drilling in concrete, sand-lime brick, natural stone, brickwork, clinker.

All drill bits by Heller have the independent PGM certificate, assuring safe connection systems.
