Cleveland C08686 Taper Length Drill Bit No. 22 Hss

Product Description

The CLEVELAND C08686 is a taper length, high-speed steel drill bit designed for general-purpose drilling in metalworking and fabrication applications. It carries a No. 22 wire gauge size with a decimal diameter of 0.1570 inches and a 118-degree standard point angle. The flute length measures 3-3/8 inches and the overall length is 5-3/4 inches, giving it extended reach compared to jobber-length bits without sacrificing rigidity. The web-thinned, tapered web design reduces thrust at the point and improves chip evacuation. The coated finish provides added surface hardness for extended tool life in production environments.

This bit is suited for drilling alloy steel, carbon steel, and cast iron in both shop and field settings. The taper length configuration makes it a practical choice when standard jobber bits fall short on reach, such as drilling through thicker workpieces, structural sections, or deep-clearance applications. It is commonly used by machinists, millwrights, pipefitters, and maintenance tradespeople working with ferrous materials. The straight shank seats in standard drill chucks without adapters, making it compatible with most portable and benchtop drilling equipment.

Key Features

• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High-speed steel construction rated for general-purpose metalworking
• Taper length body at 5-3/4 inches OAL provides extended reach versus jobber-length bits
• Right-hand spiral flute promotes efficient chip removal during drilling
• Straight shank at 0.1570 inch diameter fits standard drill chucks without adapters
• Meets ASME B94.11M and DIN 340 dimensional standards

Compatibility

Designed for drilling alloy steel, carbon steel, and cast iron. Straight shank fits standard three-jaw drill chucks on portable drills, drill presses, and milling machine spindles.

Installation Notes

Installation and use should be performed by a qualified machinist or tradesperson familiar with drilling operations and applicable shop safety standards. Secure the workpiece firmly before drilling and ensure the chuck is fully tightened on the shank before operation. Always power down and de-energize the drill or machine before changing bits. Use appropriate cutting fluid when drilling ferrous metals to extend tool life and maintain hole tolerance.
