Milwaukee SDS Plus 4-Cutter MX4 1″ x 8″ x 10″ Drill Bit 48-20-7240

MAXIMUM DURABILITY FOR REINFORCED CONCRETE DRILLING

When your crew is drilling into hard aggregate or encountering embedded rebar, tool downtime is the primary obstacle to productivity. The Milwaukee MX4 4-Cutter SDS Plus bit is engineered to eliminate the binding and lock-ups that snap standard bits. By utilizing a solid head carbide design, this bit maintains its structural integrity through 5X more cycles than conventional cutters. The variable flute geometry is a mechanical advantage that optimizes dust extraction, which directly reduces thermal stress on the bit and allows your rotary hammers to deliver up to 20% more holes per battery charge. This is a high-ROI consumable designed for the professional who demands precision and longevity in the most demanding masonry applications.

• / Solid head carbide construction provides up to 5X longer life in concrete with rebar compared to standard bits.
• / 4-cutter geometry prevents lock-up and binding when hitting rebar, significantly reducing bit breakage.
• / Sharp centering tip ensures exact spot drilling and prevents bit walking on concrete or metal decking.
• / Variable flute design accelerates dust removal, reducing heat buildup and increasing cordless runtime.
• / Integrated wear mark indicator provides a clear visual cue for bit replacement to maintain ANSI anchor fitment standards.
