The Milwaukee Electric Tool Corp 48-89-2203 is a 3/32-inch titanium-coated high-speed steel drill bit sold in a 2-pack under the Thunderbolt line. The titanium oxide coating extends service life up to three times longer than standard high-speed steel bits. A 135-degree split point tip eliminates walking at startup and allows fast penetration without a center punch. The Thunderbolt core construction resists breaking under load. These bits are sized for general-purpose work and are well-suited for use in cordless drills, making them a practical addition to any field kit or service van.
These drill bits are intended for general-purpose drilling in wood and metal. The 3/32-inch diameter is commonly used for pilot holes, light fastener clearance, and small-diameter through-holes in sheet metal, light-gauge steel, softwood, and hardwood. The 2-pack format supports high-turnover environments where bit replacement is routine. Cordless drill compatibility makes them practical for service technicians and installers working without consistent access to a power outlet.
Designed for general-purpose drilling in wood and metal using standard cordless or corded drills with a 3/32-inch chuck capacity or larger.
These bits are installed and removed by a licensed or qualified tradesperson using a standard keyless or keyed drill chuck. Ensure the drill is powered off and the battery is removed before changing bits. Use appropriate eye protection during drilling operations. Follow applicable safety codes and tool manufacturer guidelines for bit speed and feed rate by material type.
