Cleveland C08863 Taper Length Drill Bit 21/32 in Hss

Product Description

The CLEVELAND C08863 is a taper length drill bit designed for general-purpose drilling in metalworking applications. Built from high-speed steel with a coated finish, it delivers consistent performance across a range of ferrous materials. The bit features a 118-degree standard point angle, a spiral flute with web-thinning for improved chip evacuation, and a straight shank measuring 0.6562 inches in diameter. At 9 inches overall length with a 5.125-inch flute length, it reaches deeper than jobber-length bits while maintaining rigidity. Licensed machinists, tool and die workers, and maintenance mechanics are the primary installers.

This drill bit is suited for production and maintenance drilling in alloy steel, carbon steel, and cast iron. The taper length design provides additional reach for applications where standard jobber bits fall short, making it a practical choice for structural fabrication, maintenance shops, and industrial machining environments. The right-hand spiral flute and web-thinned geometry reduce thrust requirements and improve hole quality across typical shop setups.

Key Features

• High-speed steel construction with coated finish for extended tool life in ferrous materials
• 118-degree standard point angle for general-purpose drilling in alloy steel, carbon steel, and cast iron
• Taper length body at 9 inches OAL provides added reach beyond jobber-length bits
• Web-thinned, tapered web geometry reduces drilling thrust and improves chip flow
• Straight shank at 0.6562 inches diameter fits standard drill chucks and collets
• Conforms to ASME B94.11M and DIN 340 standards

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard straight-shank drill chucks and collets sized for a 0.6562-inch shank. Rated for use in alloy steel, carbon steel, and cast iron per manufacturer specification.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance personnel familiar with rotating cutting tools. Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Always power down and lock out the machine before changing bits or making chuck adjustments. Refer to the machine manufacturer and applicable shop safety standards for feed rate and speed recommendations based on material and hole depth.
