The MILWAUKEE ELECTRIC TOOL CORP 48-89-2319 is a RED HELIX cobalt drill bit designed for drilling through hard metals, stainless steel, and other tough materials. Sized at 11/32 inches, it is sold in a 3-pack and is built around a cobalt construction that resists heat buildup during high-speed drilling operations. The RED HELIX geometry is engineered to evacuate chips efficiently and maintain cutting performance over repeated use. This bit is a standard tool for electricians, plumbers, HVAC technicians, and metal fabricators who regularly drill through structural steel, equipment housings, or heavy-gauge sheet metal.
The 48-89-2319 is suited for use in both residential and commercial trade work where metal drilling is a recurring task. At 11/32 inches, the bit produces a hole size common in conduit mounting, pipe hanger installation, and equipment bracket fabrication. The 3-pack quantity makes it a practical choice for service vans and shop benches where bit replacement is frequent due to high-cycle use on hard materials.
Designed as an OEM-style replacement-grade cobalt drill bit compatible with standard 3-jaw drill chucks and keyed chuck drivers accepting round-shank bits.
Cobalt drill bits should be installed by a qualified tradesperson using a properly rated drill or drill press. Secure the workpiece firmly before drilling and use cutting fluid on hard metals to extend bit life and reduce heat. Always wear appropriate eye protection when drilling metal. Inspect the bit for wear or chipping before each use and replace if the cutting edge is compromised.
