Key Features & Benefits:
- Made for Hard Materials: Ideal for penetrating hard and abrasive metals.
- Stays Sharp, Lasts Longer: C-2 carbide construction ensures bits stay sharp and last longer.
- Built Tougher Than HSS: Chrome vanadium shanks offer more durability and longevity than traditional HSS steel.
- Drills Faster: Flat-ground to a 118-degree angle for added durability and higher turning rates.
- Clears Debris Easily: Large flute capacity minimizes clogging with easier debris removal.
- Handles the Heat: High-temperature tip brazing allows the bits to handle higher heat levels.
- Concrete and Rebar, Same Bit: Save time by drilling through concrete and rebar with the same bit — with or without hammer mode.
