Cleveland C08835 Taper Length Drill Bit 31/64 in Hss

Product Description

The CLEVELAND C08835 is a taper length, straight-shank drill bit from the Series 2510 line, designed for general-purpose drilling in metalworking applications. Built from high-speed steel (HSS) with a coated finish, this bit features a 31/64-inch diameter, a 118-degree standard point, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The right-hand spiral flute measures 4.75 inches in length, and the overall length is 7.75 inches, giving it more reach than a jobber-length bit while maintaining rigidity. Machinists, maintenance technicians, and metalworking trades reach for taper length bits when jobber-length tools lack the reach needed for deeper holes.

This bit is suited for drilling into alloy steel, carbon steel, and cast iron. The taper length design makes it a practical choice for production drilling, fixture work, and general shop operations where added flute length is needed beyond a standard jobber bit. The straight shank is compatible with standard drill chucks and milling machine collets. The 31/64-inch diameter is commonly used where a close tolerance bore or a pre-tap hole is required in ferrous materials.

Key Features

• High-speed steel construction with coated finish for wear resistance on ferrous materials
• 118-degree standard point angle for general-purpose entry into steel and cast iron
• Web-thinned, tapered web reduces cutting thrust and improves chip flow
• Taper length body provides extra reach compared to jobber-length drills
• Right-hand spiral flute with regular helix for consistent chip evacuation
• Meets ASME B94.11M and DIN 340 standards

Compatibility

Designed for use in alloy steel, carbon steel, and cast iron. The straight shank fits standard three-jaw drill chucks and compatible collet systems. Part of the Cleveland Series 2510 taper length drill line.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the workpiece firmly before drilling and ensure the chuck or collet is fully tightened to the correct shank diameter before operation. Do not exceed the recommended speed and feed for the workpiece material and bit diameter. Inspect the cutting edges for wear or damage before each use and replace the bit if chipping or dulling is observed.
