Cleveland C08737 Taper Length Drill Bit 15/64 in Hss

Product Description

The CLEVELAND C08737 is a taper length high speed steel drill bit designed for general-purpose drilling in metal and ferrous materials. At 15/64 inch (0.2344 inch) diameter, it features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation at entry. The spiral flute geometry and right-hand cut make it a direct fit for standard drill presses and hand-held drill drivers. Licensed machinists, HVAC fabricators, pipefitters, and maintenance technicians are the typical end users. The 6-1/8 inch overall length provides added reach in confined or deep-clearance applications where a jobber-length bit falls short.

This bit is suited for drilling alloy steel, carbon steel, and cast iron in both shop and field environments. The extended taper length body gives it an advantage in applications requiring deeper hole entry without repositioning — such as structural steel fabrication, mechanical room rough-in work, and equipment maintenance. The coated high speed steel construction provides improved wear resistance compared to uncoated HSS. It is sold individually and is appropriate for use in any standard straight-shank chuck accepting a 15/64 inch shank.

Key Features

• 15/64 inch (0.2344 inch) diameter with matching straight shank — fits standard drill chucks without adapters
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• 3-3/4 inch spiral flute length promotes consistent chip clearance during deep drilling
• 6-1/8 inch overall length provides extended reach beyond standard jobber-length bits
• Coated high speed steel construction for improved wear resistance on alloy steel, carbon steel, and cast iron
• Right-hand cut, regular spiral — compatible with all standard forward-rotation drill equipment
• Meets ASME B94.11M and DIN 340 standards for dimensional accuracy and performance

Compatibility

Rated for drilling alloy steel, carbon steel, and cast iron. Designed for use in any straight-shank chuck accepting a 15/64 inch shank diameter. Suitable for drill presses, magnetic-base drills, and standard hand-held drill drivers used in general-purpose machining and trade applications.

Installation Notes

Secure the bit fully in the chuck and verify runout before drilling. Use cutting fluid or a suitable lubricant when drilling steel to extend tool life and improve hole finish. Apply steady, consistent feed pressure — excessive force on a taper-length bit can cause deflection or premature tip wear. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
