Milwaukee 48-89-2221 Titanium Drill Bit 3/8 Inches

Product Description

The Milwaukee Electric Tool Corp 48-89-2221 is a 3/8-inch titanium-coated twist drill bit built 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, making it a cost-effective choice for tradespeople who run through bits regularly. A 135-degree split point tip starts cutting on contact without walking, reducing layout time and the need for a center punch. The Thunderbolt core is engineered to resist breaking under the lateral stress common in cordless drill applications.

This drill bit is suited for residential and light commercial work where tradespeople need a reliable general purpose bit for framing, metal stud drilling, rough-in work, and miscellaneous fastener prep. The design is optimized for use in cordless drills, which are standard on most job sites today. It is sold in a skin-carded package and is available in a package quantity of 150 units, making it practical for stocking shop carts or gang boxes.

Installation Notes

This bit is installed by a qualified tradesperson into any drill accepting a 3/8-inch shank. Ensure the drill chuck is fully tightened before operation and confirm the workpiece is secured before drilling. When drilling metal, use appropriate cutting fluid where required to extend bit life.
