Milwaukee 48-89-4613 1/4 Inch Titanium Impact Drill Bit 5 Pack

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-89-4613 is a 1/4 inch titanium-coated impact duty drill bit sold in a 5-pack under the Shockwave line. Engineered specifically for impact drills, these bits feature a variable helix design with an aggressive 35-degree helix angle that transitions to a 15-degree angle. This geometry promotes rapid chip removal to limit heat buildup, helping the cutting edge stay sharp through demanding drilling cycles. The 135-degree split point tip provides a precision start and reduces walking, enabling fast and accurate hole placement. Licensed trade contractors and experienced tradespeople use these bits for production drilling in metal, wood, and composite materials.

These impact duty bits are designed for use with impact drivers and hammer drills in a wide range of drilling applications. The titanium coating is rated to deliver up to 3 times the service life compared to standard black oxide drill bits. The 5-pack configuration suits tool bags, service vans, and job site kits where bit redundancy reduces downtime. Applications span residential and light commercial work including electrical rough-in, plumbing layout, HVAC mounting, and general fastening tasks that require consistent, repeatable hole quality.

Installation Notes

Installation is performed by the end user inserting the bit into a compatible impact driver or drill chuck. Ensure the chuck is fully tightened and the drill is powered off before changing bits. Follow applicable OSHA and site safety requirements for rotating tool use, including eye protection. Avoid applying lateral pressure during drilling to preserve tip geometry and extend bit life.
