- Drill bits fit most SDS-max rotary hammers and Hilti TE F, G and Y rotary hammers
- Each drill bit has a chrome vanadium shaft that’s through-hardened to 50-53HrC
- Flute geometry removes dust from the hole quickly for fast drilling and long life
- IRWIN drill bits have a shot-peened, double-tempered finish that helps reduce breakage
- Copper braze material gives high heat resistance for reduced tip loss
