Milwaukee 1-1/8" One-Piece Carbide Hole Cutter

INDUSTRIAL-GRADE CARBIDE PRECISION

When your crew is facing 304 stainless steel or thick-gauge structural metals, standard bi-metal saws won't cut it for long-term fleet ROI. The Milwaukee 49-57-8615 is engineered to eliminate the high failure rates associated with metal drilling. Featuring a robust one-piece design and precision-ground carbide teeth, this cutter provides the mechanical stability required to prevent tooth-stripping under high-torque applications. By integrating a stop-shoulder and a spring-loaded pilot bit, this tool maximizes jobsite production while ensuring that every penetration is controlled, clean, and repeatable without the risk of over-drilling into sensitive internal components.

• / CARBIDE TEETH TECHNOLOGY: Delivers significantly longer service life than high-speed steel or bi-metal alternatives when tackling hard metals like stainless steel.
• / INTEGRATED STOP SHOULDER: Engineered to prevent over-drilling, limiting the depth to a precise 3/16" for consistent, safe performance in panel and sheet metal work.
• / SPRING-LOADED PILOT BIT: Provides automatic plug ejection upon completion of the cut, drastically reducing downtime between holes.
• / 3-FLAT SECURE-GRIP SHANK: Eliminates bit slippage within the drill chuck, ensuring maximum power transfer and reducing wear on the tool's drive system.
