Cleveland C08631 Taper Length Drill Bit Wire 46 Hss

Product Description

The CLEVELAND C08631 is a taper length, straight-shank drill bit designed for general-purpose drilling in metal fabrication and maintenance applications. Built from high-speed steel (HSS) with a coated finish, it carries a standard 118-degree split point and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The wire gauge size is 46, equal to 0.0810 inches in decimal. Flute length is 2.25 inches and overall length (OAL) is 4.25 inches. The spiral flute and right-hand cut geometry make it compatible with standard drill presses, hand drills, and CNC drilling setups. Licensed machinists, millwrights, pipefitters, and industrial maintenance techs are the primary users.

This bit is suited for through-hole and clearance drilling in alloy steel, carbon steel, and cast iron. The taper length body provides additional reach compared to a jobber-length bit, making it practical for deeper holes or setups where a longer flute is required without stepping up to a full extra-long series. It is sold individually with a minimum order quantity of 10 units, making it appropriate for shop restocking or tool-crib inventory management.

Key Features

• High-speed steel construction rated for alloy steel, carbon steel, and cast iron
• Coated finish extends tool life in general-purpose drilling operations
• Right-hand spiral flute with regular spiral type for efficient chip removal
• Meets ASME B94.11M and DIN 340 standards

Compatibility

Designed for use in materials including alloy steel, carbon steel, and cast iron. Fits any standard drill chuck or collet accepting a 0.0810-inch straight shank. Suitable for Series 2510 general-purpose drilling applications per ASME B94.11M and DIN 340.

Installation Notes

Secure the bit firmly in the chuck before operation and verify runout is within acceptable limits. Power down and de-energize any drill press or CNC spindle before changing bits. Use appropriate cutting fluid for steel applications to maintain edge life. Dispose of worn HSS tooling per applicable shop safety procedures.
