Cleveland C08663 Taper Length Drill Bit Wire 31 Hss

Product Description

The CLEVELAND C08663 is a taper length drill bit 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 thrust and improves chip evacuation. It carries a wire gauge size of 31, corresponding to a decimal diameter of 0.1200 inches. The spiral flute geometry and right-hand cutting direction make it a reliable choice for licensed machinists, maintenance technicians, and skilled tradespeople working with ferrous metals and cast iron.

This bit is suited for drilling alloy steel, carbon steel, and cast iron in both shop and field environments. The taper length design provides greater reach than a jobber-length bit while maintaining rigidity, making it appropriate for applications where standard-length bits fall short. With a straight shank diameter of 0.1200 inches and an overall length of 5.125 inches, it fits conventional drill chucks without adapters. It is packaged individually and sold as a single unit.

Key Features

• Wire gauge size 31 with a decimal diameter of 0.1200 inches for precise hole sizing
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High-speed steel construction with coated finish for improved wear resistance
• Taper length design at 5.125 inches overall length provides extended reach versus jobber bits
• Right-hand spiral flute promotes efficient chip removal during through-hole and blind-hole drilling
• Meets ASME B94.11M and DIN 340 standards for dimensional and performance consistency

Compatibility

Designed for use in alloy steel, carbon steel, and cast iron applications. Suitable for use with standard drill chucks accepting a 0.1200-inch straight shank. Intended for general-purpose drilling in Series 2510 taper length configurations.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or tradespeople familiar with drill press or hand drill operation. Secure the straight shank firmly in a compatible chuck and verify concentricity before drilling. Power down all equipment before changing bits or adjusting chuck settings. Do not exceed the recommended feed and speed parameters for the workpiece material being drilled.
