Product Description
Key Features
- Uniformly Brazed Carbide Inserts - Precision brazing ensures consistent carbide bonding for longer bit life and reliable performance over extended use.
- Self-Centering Tips - Accurate hole placement from the first strike, reducing the need for repositioning and improving productivity.
- Chromium-Nickel-Molybdenum Steel Alloy Body - High-grade steel alloy construction ensures superior hammering quality and an extended service life under heavy-duty conditions.
- Heat-Treatment & Shot-Peened Finish - Proprietary heat-treatment procedures combined with a shot-peened finish increase surface hardness, boost drilling speed, reduce drill bit wear, and improve resistance to bending forces.
- ANSI Standard B212.15 Compliant - Drill bit conforms to ANSI Standard B212.15, meeting precise industry tolerance requirements.
- High-Volume, Multi-Flute Spiral - Rapidly channels concrete dust away from the hole to maintain clear cutting paths and improve drilling speed.
- 4 x 90 deg. Quad-Head Geometry - Crushes through rebar and prevents the bit from sticking in reinforced concrete, improving safety and efficiency.
- Patented Reinforced Core Flute - The high-performance, reinforced core flute design maximizes energy transfer for faster, more effective drilling.
- Proprietary Flute Geometry - Reduces vibration, optimizes impact energy transfer from the rotary hammer into the drill bit tip, enhancing drilling speed and durability while reducing operator fatigue.
- SDS-Max Shank - Compatible with SDS-max rotary hammers for secure, tool-free bit changes and reliable torque transmission.

Frequently Asked Questions
- What shank type does this drill bit use, and which tools is it compatible with?
- This drill bit features an SDS-max shank, making it compatible with SDS-max rotary hammers. The SDS-max shank system is designed to optimize impact energy transfer from the rotary hammer into the drill bit tip, enhancing drilling speed and durability.
- What are the key dimensions and drilling depth of this bit?
- The bit has a diameter of 7/8 in. and an overall length of 13 in. The maximum drilling depth is 8 in.
- Can this bit drill through rebar in reinforced concrete?
- Yes. The quad-head design features a 4 x 90 deg. head geometry that is specifically engineered to crush through rebar and prevent the bit from sticking in reinforced concrete, improving both safety and efficiency during use.
- What materials and manufacturing processes are used to ensure the durability of this bit?
- The bit body is constructed from a chromium-nickel-molybdenum steel alloy for superior hammering quality and extended service life. It undergoes proprietary heat-treatment procedures and a shot-peened finish that increase surface hardness, boost drilling speed, reduce wear, and improve resistance to bending forces. The carbide inserts are uniformly brazed for consistent bonding and longer bit life. The bit also conforms to ANSI Standard B212.15.
