Cleveland C08879 Taper Length Drill Bit 25/32 in Hss

Product Description

The CLEVELAND C08879 is a taper length, high-speed steel drill bit designed for general-purpose drilling in metal fabrication and maintenance applications. Built to Series 2510 standards, it measures 25/32 inches (0.7812 inches) in diameter with a 9-7/8 inches overall length and a 6 inches flute length. The 118-degree standard point angle delivers reliable entry geometry across a wide range of ferrous materials. A web-thinned, tapered web configuration reduces thrust during penetration. The straight shank accepts standard drill chucks without an adapter, and the right-hand spiral flute evacuates chips efficiently during cutting.

This drill bit is suited for production and maintenance drilling in alloy steel, carbon steel, and cast iron. The taper length body provides additional reach compared to a jobber-length bit, making it practical for deeper hole applications where a standard-length bit falls short. It is commonly used by machinists, millwrights, and general maintenance technicians working on structural and mechanical assemblies. Coolant-through capability is not available on this model, so external coolant or cutting fluid should be applied when drilling harder alloys.

Key Features

• 25/32 inch diameter with a tight tolerance of +0.0000 to -0.0012 inches for consistent hole sizing
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High-speed steel construction with coated finish for improved wear resistance
• 6 inches flute length and 9-7/8 inches overall length for extended reach in taper length applications
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Straight shank with 25/32 inch shank diameter fits standard drill chucks directly
• Meets ASME B94.11M and DIN 340 standards

Compatibility

Designed as a general-purpose taper length drill bit for use in alloy steel, carbon steel, and cast iron applications. Compatible with any drill press, magnetic drill, or hand drill equipped with a chuck that accepts a 25/32 inch straight shank.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drill press and hand-drill operation. Ensure the workpiece is securely clamped and the machine is powered down before mounting or removing the bit. Apply appropriate cutting fluid or external coolant when drilling harder ferrous materials to extend tool life and maintain dimensional accuracy. Follow ASME B94.11M guidelines for drill bit handling and storage.
