Cleveland C08881 Taper Length Drill Bit 51/64 in Hss

Product Description

The CLEVELAND C08881 is a taper length twist drill bit designed for production drilling in metal fabrication and general machining 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 at entry. The straight shank measures 0.7969 inches in diameter, and the overall length is 10 inches, giving technicians additional reach over a jobber-length bit without sacrificing rigidity. The spiral flute geometry is right-hand cut with a regular spiral type, making it compatible with standard drill press and handheld drilling equipment.

This bit is sized at 51/64 inches (0.7969 inches decimal) and belongs to the Series 2510 taper length family. It is suited for drilling into alloy steel, carbon steel, and cast iron in both shop and field environments. The 6.125-inch flute length accommodates deeper holes than standard jobber bits, making it a practical choice for structural, mechanical, and maintenance work where stack thickness or hole depth exceeds what a jobber bit can reach. It is typically used by machinists, millwrights, and maintenance technicians on drill presses, mag drills, or heavy-duty corded drills.

• Right-hand cut, straight shank compatible with standard drill chucks
• Meets ASME B94.11M and DIN 340 standards

Compatibility

Rated for general-purpose drilling in alloy steel, carbon steel, and cast iron. Designed as a Series 2510 taper length replacement bit for use in standard straight-shank drill chucks on drill presses and handheld power drilling equipment.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the straight shank firmly in the chuck and verify concentricity before drilling. Always power down and de-energize the drilling equipment before changing bits. Use appropriate cutting fluid when drilling ferrous metals to manage heat buildup and preserve cutting edge life.
