Cleveland C71009 9/64 Inch Hss Jobber Drill Bit

Product Description

The CLEVELAND C71009 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. It measures 9/64 inch (0.1406 inch decimal) in diameter with a 2-7/8 inch overall length and a 1-3/4 inch spiral flute. The 118-degree standard point angle suits a wide range of common materials, and the oxide finish provides basic lubrication and corrosion resistance during use. The straight-cylindrical shank seats securely in standard 3-jaw drill chucks. This bit is part of the Cleveland Series 2001G line and conforms to ASME B94.11M and DIN 338 standards. It is a single-piece unit intended for use by machinists, pipefitters, electricians, and HVAC technicians requiring precision pilot holes or through-holes in light-gauge material.

This bit is suited for light industrial and trade applications where a reliable, general-purpose jobber drill is needed. Common uses include drilling pilot holes for fasteners, conduit knockouts, sheet metal penetrations, and similar tasks encountered in mechanical, electrical, and plumbing service work. The 4xD flute-to-diameter ratio provides adequate chip clearance for drilling in ferrous and non-ferrous metals as well as plastics. The web-thinned, tapered-web geometry reduces thrust at entry and helps maintain straightness in shallow to moderate-depth holes.

Key Features

• 9/64 inch diameter (0.1406 inch decimal) with diameter tolerance of -0.0007 to 0.0000 inches for consistent hole sizing
• 118-degree standard point angle for general-purpose use across metals, plastics, and wood
• High speed steel construction with oxide coating for basic lubrication and extended service life
• Web-thinned, tapered-web design reduces drilling thrust and improves point engagement
• Right-hand cut, 2-flute spiral configuration with 1-3/4 inch flute length for effective chip evacuation
• Conforms to ASME B94.11M and DIN 338 standards; Series 2001G

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard 3-jaw keyed or keyless drill chuck that accepts a straight-cylindrical shank of 0.1406 inch diameter, including benchtop drill presses, hand drills, and right-angle drill attachments commonly used in trade work.

Installation Notes

This bit is installed and removed by a licensed or qualified tradesperson using a standard drill chuck and chuck key where applicable. Ensure the drill or drill press is fully de-energized and the chuck is secured before beginning drilling operations. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain hole tolerance. Follow applicable safety standards for rotating cutting tools per OSHA 29 CFR 1910.212 when used in shop or field environments.
