Milwaukee 48-89-2217 Titanium Drill Bit 5/16 Inches

Product Description

The Milwaukee Electric Tool Corp 48-89-2217 is a 5/16-inch titanium-coated twist drill bit engineered for general-purpose drilling in wood and metal. The titanium oxide coating extends service life up to three times longer than standard high-speed steel bits, reducing bit replacement frequency on busy job sites. The 135-degree split point tip starts cutting immediately without walking or center-punching the workpiece. The Thunderbolt core construction is designed to resist breaking under the lateral loads common in cordless drill use. This bit is suited for electricians, plumbers, HVAC technicians, and general contractors who drill through framing, sheet metal, and structural members as part of daily trade work.

The 48-89-2217 is designed for general-purpose drilling applications across wood and metal substrates. It performs reliably in cordless drills, making it practical for field work where corded power is not always available. Typical applications include drilling pilot holes, clearance holes, and access holes through lumber, light-gauge steel, aluminum, and similar materials encountered in residential and light commercial construction and service work. The skin-carded packaging is suited for retail display or individual unit distribution.

Installation Notes

Insert the bit fully into the drill chuck and tighten securely before use. Apply steady, consistent feed pressure and allow the split point to establish the hole before increasing speed. When drilling metal, use appropriate cutting fluid to reduce heat buildup and extend bit life. Wear eye protection in accordance with applicable jobsite safety requirements.
