Cleveland C09756 Taper Length Drill Bit 7/16 Inches Hss

Product Description

The CLEVELAND C09756 is a taper length, high-speed steel drill bit engineered for general-purpose drilling in metal fabrication and maintenance applications. Built to Series 950E specifications, it features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation at entry. The right-hand spiral flute geometry promotes consistent chip clearing throughout the cut. At 12 inches overall length with a 9-inch flute, this bit reaches deeper than a jobber-length drill without sacrificing rigidity, making it a go-to for structural and fabrication work where access depth matters. Diameter tolerance is held to +0.0000 to -0.0010 inches, consistent with ASME B94.11M.

This drill bit is suited for drilling alloy tool steel, carbon steel, and cast iron in both shop and field settings. The straight shank measures 7/16 inches in diameter with a 3-inch shank length, fitting standard drill chucks without adapters. The taper length profile is commonly used by machinists, pipefitters, ironworkers, and mechanical contractors who need extended reach for through-hole drilling in plate, structural steel, or heavy-wall pipe flanges. It is not designed for coolant-through use and is intended for dry or externally applied cutting fluid applications.

• 9-inch spiral flute length for effective chip evacuation in deep holes
• 12-inch overall length provides extended reach beyond standard jobber-length bits
• Right-hand cut, straight shank — fits standard drill chucks without adapters
• Manufactured to ASME B94.11M standards; diameter tolerance +0.0000 to -0.0010 inches

Compatibility

Designed for general-purpose use in alloy tool steel, carbon steel, and cast iron. Fits standard drill chucks accepting a 7/16-inch straight shank.

Installation Notes

Installation should be performed by qualified machinists or trade professionals familiar with drilling operations on metal substrates. Secure the workpiece firmly before drilling and ensure the chuck is fully tightened on the straight shank before operation. Apply appropriate cutting fluid for the material being drilled to extend tool life and maintain hole quality. Inspect the cutting edges and web condition before each use — a damaged point should be reground or the bit replaced.
