Milwaukee 48-89-4618 Titanium Drill Bit 21/64 in 3-pack

Product Description

The MILWAUKEE ELEC TOOL 48-89-4618 is a 21/64-inch Shockwave Impact Duty Titanium Drill Bit sold in a 3-pack. It is engineered for use with both impact drivers and standard drills, making it a versatile option for licensed electricians, plumbers, HVAC technicians, and general contractors who drill frequently through metal, wood, and similar materials. The titanium coating extends service life significantly compared to standard black oxide bits. A variable helix design transitions from an aggressive 35-degree angle to a 15-degree angle, promoting rapid chip evacuation and reducing heat buildup to keep the cutting edge sharper longer.

This drill bit is suited for residential and commercial trade applications where speed and accuracy are priorities. The 135-degree split point tip starts on contact without center-punching, preventing the bit from walking on smooth or curved surfaces. The red helix design provides quick visual identification in a toolbox or pouch. Typical use cases include drilling pilot holes, anchor holes, and pass-through holes in metal framing, junction boxes, pipe straps, and structural lumber. The 3-pack quantity reduces downtime when one bit dulls mid-job.

Installation Notes

Install and remove drill bits only when the tool is powered off and the trigger is locked out. Secure the bit fully in the chuck before applying power. When drilling metal, use appropriate cutting fluid where required to extend bit life and reduce heat. Follow applicable OSHA and site-safety requirements for drilling operations in occupied structures.
