SDS Max Multi-Cutter Drill Bits

Century Drill & Tool 83705 Sonic SDS Max Multi-Cutter Drill Bits are professional-grade accessories for rotary hammers that accept SDS Max shanks. They target contractors and tradespeople who drill anchor and through-holes in reinforced concrete on a daily basis. The multi-cutter tip geometry is engineered to resist binding when hitting rebar. Wear-mark indicators on every bit give a clear visual cue when the cutting diameter has fallen below anchoring tolerance.

Fits SDS Max Rotary Hammers

These bits lock directly into any SDS Max chuck without adapters, freeing the user from the slower SDS Plus step-up route. The self-centering crushing point starts holes cleanly without a separate pilot drill, reducing set-up time on each location. Reinforced crushing tips dampen vibration transmitted to the tool and operator, which helps preserve both the hammer mechanism and the carbide edges during extended runs.

Upgrade from Standard Masonry Bits

The cutting action crushes concrete up to 20 times faster than conventional masonry twist drills, turning a multi-minute hole into a matter of seconds. That speed gain pays off most on projects with dozens of anchor points or deep through-holes where cumulative time savings are measurable. The jump is less justified for occasional single-hole tasks in soft block or brick where a basic bit already finishes quickly.
