Milwaukee 48-89-2307 Cobalt Drill Bit 5/32 Inches

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-89-2307 is a 5/32-inch cobalt drill bit engineered for specialty drilling in hard metals. The 135-degree split point tip starts cuts immediately without walking, reducing the need for a center punch on most surfaces. The Thunderbolt core construction resists breaking under the lateral stress common in hard-metal applications. This bit is well-suited for use in cordless drills, making it practical for field work where a corded power source is not always available. Electricians, plumbers, HVAC technicians, and general trade professionals who regularly drill into stainless steel or other hard metals will find this bit appropriate for their workflow.

This cobalt drill bit is designed for specialty drilling in hard metals including stainless steel. The 5/32-inch diameter suits smaller fastener and anchor pilot holes common in mechanical and electrical trade applications. It performs reliably in both corded and cordless drill drivers, making it adaptable to shop or on-site conditions. The package contains 5 bits per unit, providing spares for extended jobs or crew use.

Installation Notes

Licensed trade professionals and experienced users should secure the workpiece before drilling to prevent movement. Always wear appropriate eye protection when drilling hard metals. Confirm chuck size compatibility before inserting the bit, and apply consistent feed pressure to avoid overheating the tip. Reduce feed rate when breaking through the back side of the material to maintain bit integrity.
