Product Description
Key Features
- Uniformly Brazed Carbide Inserts - Precisely and uniformly brazed carbide inserts result in longer bit life and consistent cutting performance over extended use.
- Self-Centering Tips - Self-centering tips ensure accurate hole placement from the first strike, reducing walk and improving precision.
- Chromium-Nickel-Molybdenum Steel Alloy Body - The premium steel alloy body is engineered to withstand the rigors of heavy rotary hammer use, ensuring superior hammering quality and extended service life.
- Heat-Treatment & Shot-Peened Finish - Advanced heat-treatment procedures combined with a shot-peened finish increase surface hardness, accelerate drilling speed, reduce bit wear, and improve resistance to bending forces.
- ANSI Standard B212.15 Conformance - Drill bit is designed and manufactured to conform to ANSI Standard B212.15 for consistent, reliable performance.
- High-Volume Multi-Flute Spiral - The high-volume, multi-flute spiral design rapidly channels concrete dust away from the hole bottom to improve drilling speed and reduce clogging.
- 4 x 90 deg. Quad-Head Geometry - The 4 x 90 deg. head geometry crushes through rebar and actively prevents the bit from sticking in reinforced concrete, keeping work moving without interruption.
- Patented Reinforced Core Flute - The patented, high-performance reinforced core flute is engineered to maximize energy transfer from the rotary hammer into the drill bit tip, enhancing both speed and durability.
- Proprietary Flute Geometry - Reduces vibration and optimizes impact energy transfer from the rotary hammer into the drill bit tip, which enhances drilling speed and durability while reducing noise and operator fatigue.
- SDS-Max Shank - Designed to fit the SDS-max rotary hammer chuck system for secure, tool-free bit changes and reliable torque transmission.

Frequently Asked Questions
- What shank type does this drill bit use, and is it compatible with standard rotary hammers?
- This drill bit features an SDS-max shank, which is designed for use with SDS-max rotary hammers. It is not compatible with SDS-plus tools, so be sure your rotary hammer accepts the SDS-max shank format before use.
- What are the overall length and maximum drilling depth of this bit?
- The bit has an overall length of 21 inches and a maximum drilling depth of 15-1/2 inches. The diameter is 5/8 inch.
- Can this drill bit be used in reinforced concrete containing rebar?
- Yes. The 4 x 90 deg. quad-head geometry is specifically designed to crush through rebar and prevent the bit from sticking in reinforced concrete, allowing work to continue without interruption.
- What materials and standards ensure the durability and quality of this drill bit?
- The bit body is made from a chromium-nickel-molybdenum steel alloy engineered for heavy rotary hammer use. It features uniformly brazed carbide inserts, a heat-treated and shot-peened finish for increased surface hardness and bend resistance, and conforms to ANSI Standard B212.15 for consistent, reliable performance.
