Milwaukee 3/4" Titanium Silver & Deming Drill Bit 48-89-4640

MAXIMUM TORQUE TRANSFER FOR LARGE-DIAMETER DRILLING

When your application requires stepping up to a 3/4" hole in high-carbon steel or light gauge metal, the mechanical interface between the bit and the chuck becomes the primary point of failure. The Milwaukee 48-89-4640 Silver and Deming bit is engineered to solve this with a 1/2" Secure Grip™ shank, featuring three precision-ground flats that lock into the chuck to eliminate the spinning and heat friction that ruin standard round-shank bits. The titanium nitride coating acts as a critical thermal barrier, significantly reducing friction and extending the life of the cutting edge by up to 3X compared to oxide alternatives, ensuring a professional ROI on every jobsite.

• / 135° Split Point ensures the bit stays exactly where you mark it, preventing walking on curved or polished surfaces for a precision start.
• / Titanium Nitride (TiN) Coating provides superior heat resistance, maintaining edge hardness during high-RPM drilling in tough alloys.
• / Secure Grip™ 3-Flat Shank prevents the bit from spinning in the chuck under high-torque loads, protecting both the tool and the accessory.
• / Reduced 1/2" Shank allows for large-diameter 3/4" drilling using standard 1/2" drill/driver or hammer drill chucks.
