Cleveland C08651 Taper Length Drill Bit Wire 37 Hss

Product Description

The CLEVELAND C08651 is a taper length twist drill bit designed for general-purpose hole-making in metal fabrication and machining applications. Built from high-speed steel with a coated finish, it carries a wire gauge size of 37, which corresponds to a decimal diameter of 0.1040 inches. The 118-degree standard point angle suits a wide range of ferrous materials and provides reliable centering without a pilot hole. A web-thinned, tapered web configuration reduces thrust and improves chip evacuation. The spiral flute geometry and right-hand cut make this bit compatible with conventional drill presses, CNC machining centers, and hand-held power drills used by machinists and maintenance professionals.

This bit is sized for wire gauge 37 work in alloy steel, carbon steel, and cast iron. The taper length body — longer than a jobber bit but shorter than an extra-length bit — provides added reach for deeper holes while maintaining rigidity. It is well suited for production drilling, tool-and-die work, and maintenance-repair-operations environments where standard jobber length falls short. The straight shank fits standard drill chucks without adapters.

Key Features

• Wire size 37 (0.1040 inches diameter) with a tight diameter tolerance of +0.0000 to -0.0005 inches
• 118-degree standard point angle for reliable entry on alloy steel, carbon steel, and cast iron
• High-speed steel construction with coated finish for extended tool life
• Web-thinned, tapered web reduces drilling thrust and improves chip clearance
• Spiral flute with right-hand cut; straight shank fits standard drill chucks directly
• Conforms to ASME B94.11M and DIN 340 standards

Compatibility

Designed for use in alloy steel, carbon steel, and cast iron applications. Straight shank fits standard drill chucks sized for a 0.1040-inch shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the straight shank fully in the drill chuck before operation and verify chuck key is removed before starting the machine. Use appropriate cutting fluid or lubricant when drilling ferrous materials to extend tool life and maintain dimensional tolerance. Inspect the cutting edges for wear before each use; a dull or chipped point increases thrust and reduces hole accuracy.
