HAMMER DRILL BIT
Hammer drill bit with 4 cutting edges combines speed and long life

- Fast and reliable cutting through reinforcements of up to ø 10 mm as commonly used on construction sites
- Individually combinable with various connection options thanks to the flexible Ratio system
- Extreme durability thanks to recessed and individually soldered carbide teeth
- Optimised impact energy throughput using the SDS-plus ratio adapter
- High drilling speed and longest service life
- Please note: Drilling reinforcement only after approval by structural engineer


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.
