Milwaukee 48-20-3954 SDS Max MX4 4-Cutter 1" x 17" x 21" Drill Bit

The Milwaukee 48-20-3954 SDS Max MX4 4-Cutter Drill Bit is engineered for demanding concrete drilling applications, including concrete containing rebar and masonry. Featuring a solid head carbide construction and 4-cutter geometry, this SDS Max rotary hammer bit is designed to deliver durability, efficient drilling, and reliable performance in challenging jobsite conditions.

The 4-cutter design helps prevent lock-up when the bit encounters rebar, helping reduce downtime during drilling. Integrated rebar guards provide increased durability in hard aggregate and reinforced concrete, while the sharp centering tip supports accurate spot drilling in concrete and metal decking.

Optimized flutes are designed to remove dust efficiently, helping reduce heat during drilling while delivering up to 15% more holes per battery charge. The 17-inch usable cutting depth provides extended reach for deep drilling applications, while the 21-inch overall length supports demanding concrete and masonry work.

The Milwaukee 48-20-3954 meets ANSI B212.15 requirements for compatibility with common anchors and fits all SDS Max rotary hammers. A wear mark indicator provides a visual reference for identifying when the bit no longer meets ANSI diameter requirements.
