Cleveland C16248 Taper Length Drill Bit Wire 29 Hss

Product Description

The CLEVELAND C16248 is a taper length drill bit engineered for professional metalworking and fabrication applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 118-degree notched point with web thinning for reduced thrust and cleaner entry. The parabolic flute design promotes efficient chip evacuation, helping maintain cutting speed in deeper holes. At 0.136 inches in diameter (wire size 29), it is sized for precision work across a range of metal and non-ferrous material types. The tanged shank provides positive drive in compatible drill chucks and holders. It meets ASME B94.11M standards and is suited for use in both production and maintenance environments.

This drill bit is intended for right-hand cutting in materials including alloy steel, carbon steel, aluminum, copper alloy, stainless steel, and other non-ferrous metals. The taper length body, at 5.375 inches overall with a 3-inch flute length, gives added reach compared to jobber-length bits, making it well-suited for applications requiring deeper hole penetration without the use of extensions. It is typically used by machinists, maintenance technicians, fabricators, and general metalworking trades in both shop and field settings.

Installation Notes

This bit is installed by machinists and metalworking technicians using standard drill presses, CNC drilling equipment, or hand-held power drills with compatible chucks. Secure the tanged shank firmly in the holder before operation and verify chuck capacity matches the 0.136-inch shank diameter. Always wear appropriate eye protection and secure workpieces before drilling. Inspect the cutting edge for wear or chipping before each use, especially when working with stainless steel or hardened alloys.
