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.

All drill bits by Heller have the independent PGM certificate, assuring safe connection systems.
Patented spiral forms guarantee – for example, by means of an alternatively narrow and wide back edge – optimum removal of dust without any blow-outs. Extremely high speed with ideal transmission of impact energy thanks to computer-aided design. In addition, Heller hammer drill bits are outstanding for quiet, low-vibration operation.
