AWTOOLS SDS MAX 32x800x940mm 4-Edge Drill Bit for Concrete and Reinforced Concrete

On a busy construction site, a contractor needs to bore deep anchor holes through heavily reinforced concrete. The AWTOOLS SDS MAX drill bit, with its 32 mm diameter and 800 mm working length, powers through aggregate and rebar without binding. Its 4-edge tungsten carbide tip stays sharp, while the optimized flute design clears dust rapidly, keeping the hole clean and the bit cool.

• Compatibility: Rotary hammer drills with SDS MAX chuck

Why choose it

This bit is built for demanding drilling in hard materials. The high-temperature brazing ensures the carbide tip stays securely attached even under heavy impact. Core reinforcement and enhanced heat treatment give the bit extra rigidity and resistance to bending, while the centering tip allows precise starts without wandering. The 4-edge design distributes wear evenly, extending service life compared to standard 2-edge bits.

Ideal use cases

• Drilling anchor holes in reinforced concrete for structural connections
• Creating through-holes for pipes and conduits in concrete walls and floors
• Boring large-diameter holes in masonry and natural stone for dowels or bolts
• Demolition and renovation work where deep, accurate holes are required

Good to know

For best results, use a rotary hammer with sufficient impact energy (at least 8 joules) and set the mode to hammer drilling. Apply steady pressure without forcing the bit; let the tool do the work. Periodically withdraw the bit to clear debris from deep holes. The SDS MAX shank ensures quick, tool-free bit changes and secure locking in compatible chucks.
