Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 1/2" x 23" x 28" 48-20-3905

MAXIMIZED DURABILITY FOR HEAVY-DUTY REBAR PENETRATION

The Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit is engineered for the professional who demands mechanical reliability in the most punishing aggregate. Featuring a solid head carbide design, this bit provides up to 5x longer life compared to standard cutters when encountering rebar. The integrated 4-cutter geometry is a critical mechanical advantage, preventing the bit from locking up or binding when striking steel reinforcement, which significantly reduces tool kickback and downtime. Optimized flute geometry facilitates rapid dust extraction, lowering operating temperatures and extending the runtime of cordless SDS Max platforms by up to 15% per charge. For precision anchoring, the sharp centering tip ensures exact hole placement, while the wear mark indicators provide a clear visual gauge to ensure every hole remains compliant with ANSI B212.15 tolerances.

• / Solid Head Carbide construction delivers superior thermal resistance and 5x longer life in rebar-reinforced concrete.
• / 4-Cutter Geometry prevents binding and lock-up when hitting rebar, protecting both the user and the rotary hammer's internal clutch.
• / Optimized Flute Design accelerates dust removal to reduce friction and deliver up to 15% more holes per battery charge.
• / Wear Mark Indicators provide a definitive reference for ANSI B212.15 compliance, ensuring accurate diameter for critical anchor installations.
• / Sharp Centering Tip eliminates bit walk on smooth concrete or metal decking for precise hole initiation.
