The Milwaukee Electric Tool Corp 48-89-2209 is a titanium-coated SHOCKWAVE drill bit designed for high-demand drilling applications across a range of trade and industrial settings. Sized at 3/16 inches in diameter, this bit features a titanium surface treatment that extends cutting life compared to standard high-speed steel bits. Sold in a 275-piece pack, the 48-89-2209 is well suited for electricians, plumbers, HVAC installers, and general contractors who cycle through bits at a high rate and need a reliable bulk supply on hand.
This drill bit is intended for use in residential and light commercial construction and service work. The 3/16-inch diameter makes it a common choice for pilot holes, cable and conduit routing, and general fastener prep work. The bulk pack format supports job-site stocking, tool crib replenishment, and fleet service vehicle outfitting where maintaining a ready supply of consumable drill bits reduces downtime.
Designed as a standard 3/16-inch twist drill bit suitable for use with corded and cordless drills and impact drivers that accept standard hex or round-shank bits in that diameter range.
Drill bits of this type are installed and replaced by any trade professional using a compatible chuck or bit-holder system. Always confirm the chuck or quick-connect receiver is fully seated and locked before operating the tool. Inspect bits for wear, chipping, or heat discoloration before each use and discard damaged bits to avoid workpiece damage or injury. Follow applicable OSHA hand and power tool guidelines when operating drills on the job site.
