Cleveland C08855 Taper Length Drill Bit 39/64 in Hss

Product Description

The CLEVELAND C08855 is a taper length, straight-shank drill bit engineered for general-purpose metal drilling in trade and industrial applications. Built from high-speed steel with a coated finish, it features a 118-degree standard point and a web-thinned, tapered web configuration that reduces thrust and improves chip clearance at entry. The bit measures 39/64 inch (0.6094 inch) in diameter with a 4-7/8 inch flute length and an overall length of 8-3/4 inches. The right-hand spiral flute geometry promotes efficient chip evacuation. Machinists, pipefitters, and maintenance technicians working with ferrous metals reach for this format when a jobber-length bit is too short for the application.

This drill bit is rated for use in alloy steel, carbon steel, and cast iron. The taper length format provides additional reach compared to standard jobber-length bits, making it well suited for deep-hole drilling on structural members, pipe flanges, equipment frames, and similar workpieces where clearance or depth demands extra flute length. It conforms to ASME B94.11M and DIN 340 standards, making it appropriate for both domestic and internationally specified work. One bit is included per package.

Key Features

• High-speed steel construction with coated finish for wear resistance on ferrous materials
• 118-degree standard point angle for general-purpose drilling in alloy steel, carbon steel, and cast iron
• Web-thinned, tapered web reduces cutting thrust and improves chip flow at the drill tip
• Taper length body (8-3/4 inch OAL) provides additional reach beyond standard jobber-length bits
• Right-hand, regular spiral flute for efficient chip evacuation in through and blind holes
• Conforms to ASME B94.11M and DIN 340 standards

Compatibility

Designed as an OEM-style general-purpose taper length drill bit compatible with standard straight-shank drill chucks and collet holders accepting a 0.6094 inch shank diameter. Rated for drilling alloy steel, carbon steel, and cast iron.

Installation Notes

Installation and operation should be performed by qualified machinists or trade professionals familiar with drill press, lathe, or hand-drill safety practices. Secure the workpiece before drilling and confirm the chuck or collet is properly tightened to the straight shank before operation. Always wear appropriate eye protection and follow applicable shop safety codes. Do not exceed the recommended speed and feed range for the workpiece material and bit diameter.
