The Milwaukee Electric Tool Corp 48-32-4484 is a 2-inch T20 Torx Shockwave power bit engineered for high-demand impact fastening applications. Built from proprietary heat-treated steel, the bit delivers maximum strength and durability under the repeated stress cycles that impact drivers generate. A forged tip provides a tight, secure fit in Torx fastener heads to reduce cam-out, while the geometric shank design absorbs and redirects shock energy rather than transferring it directly to the bit body. This combination makes the 48-32-4484 a practical choice for HVAC, electrical, and plumbing tradespeople who run impact drivers daily.
This bit is suited for residential and light commercial trade work where T20 Torx fasteners are standard. It performs in wood, metal, and composite substrates and handles continuous-use impact driving without the premature tip wear common in standard bits. The 48-32-4484 ships in skin card packaging and is sold as a unit of measure of each, with a package quantity of 3 bits per pack, giving installers a ready supply on the jobsite.
Designed as an OEM-style power bit for use with standard 1/4-inch hex impact drivers and drill-drivers accepting T20 Torx drive bits.
Install into a 1/4-inch hex chuck or quick-release bit holder before operating the impact driver. Confirm the bit is fully seated and locked before applying torque. Inspect the tip for wear or rounding before each use, as a worn tip increases the risk of cam-out and fastener damage. Follow tool manufacturer torque guidelines for the specific fastener and substrate.
