Cleveland C08710 Taper Length Drill Bit No. 11 Hss

Product Description

The CLEVELAND C08710 is a taper length twist drill bit designed for general-purpose hole-making in metal and ferrous materials. Built from high-speed steel with a coated finish, this bit runs at a No. 11 wire gauge size, equal to 0.1910 inches in diameter, and features a standard 118-degree split-point geometry. The spiral flute is web-thinned with a tapered web configuration, which reduces thrust and improves chip evacuation. Overall length is 6 inches with a 3.625-inch flute length, giving it reach beyond what a jobber-length bit provides. The straight shank measures 0.1910 inches in diameter and 2.375 inches in length. Licensed machinists, toolroom operators, and maintenance technicians are the primary installers.

This bit is suited for drilling alloy steel, carbon steel, and cast iron in production and maintenance settings where standard jobber-length bits lack the reach needed. The taper length design is appropriate for drilling deeper holes in fixtures, fabrication, and repair work without stepping up to an extra-long series bit. Right-hand spiral flute geometry and the web-thinned point make this a practical choice for hand-fed or machine-fed operations at moderate speeds and feeds. It meets ASME B94.11M and DIN 340 standards, making it appropriate for applications with dimensional or quality documentation requirements.

• 118-degree standard point angle with web-thinned, tapered web configuration
• High-speed steel construction with coated finish for extended tool life in ferrous materials
• Taper length body: 6-inch overall length and 3.625-inch flute length for added reach
• Right-hand spiral flute promotes chip clearance and consistent cutting action
• Straight shank compatible with standard drill chucks and machine tool holders
• Meets ASME B94.11M and DIN 340 dimensional standards

Compatibility

Designed for drilling alloy steel, carbon steel, and cast iron. Straight shank fits standard drill press chucks, milling machine collets, and hand-drill chucks sized to accept a 0.1910-inch shank. Suitable for general-purpose machine shop and maintenance applications.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drilling operations. Secure the workpiece before drilling and confirm chuck or collet is properly tightened on the straight shank. Disconnect power to the machine before changing bits. Use appropriate cutting fluid for the material being drilled to maximize tool life and maintain dimensional accuracy.
