Cleveland C09740 Taper Length Drill Bit 3/16 Inch Hss

Product Description

The CLEVELAND C09740 is a taper length drill bit from the Series 950E line, designed for general-purpose drilling in metalworking and fabrication applications. Built from high-speed steel with a coated finish, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces walking and improves chip evacuation. With a 9-inch spiral flute length and a 12-inch overall length, the C09740 gives trades access to deeper bore depth than standard-length bits while maintaining a straight, 3/16-inch shank. It cuts right-hand and is manufactured to ASME B94.11M standards.

This bit is suited for production drilling and maintenance work in metalworking shops, mechanical contractors, and fabrication environments. Its taper length design provides additional reach compared to jobber-length bits, making it useful in tight bores, deep holes, and fixture work. Material compatibility includes alloy tool steel, carbon steel, and cast iron, making it a practical choice for HVAC sheet metal work, equipment repair, and general mechanical installation tasks.

Installation Notes

Installation is performed by machinists, fabricators, or mechanical tradespeople using a standard drill press, hand drill, or milling machine with a compatible chuck. Secure the workpiece before drilling and confirm chuck grip on the full shank length. Use appropriate cutting fluid when drilling steel to reduce heat buildup and extend bit life. Follow shop safety protocols including eye protection and secured workholding.
