Cleveland C71030 Jobber Drill Bit 15/32 in Hss Oxide

Product Description

The CLEVELAND C71030 is a jobber-length twist drill bit designed for general-purpose drilling in a wide range of materials. Built from high-speed steel with an oxide coating, it delivers consistent performance in metal, wood, and plastics. The bit measures 15/32 inch (0.4688 inch) in diameter with a 118-degree standard point angle and a 2-flute spiral configuration. Overall length is 5-3/4 inches with a 4-5/16-inch flute length. The web-thinned, tapered web construction reduces thrust and improves chip evacuation, making this bit suitable for production and maintenance drilling environments alike.

This bit is a fit for general-purpose drilling tasks in residential and commercial maintenance, mechanical contracting, plumbing rough-in, HVAC fabrication, and electrical trade work. The straight cylindrical shank seats securely in standard 3-jaw drill chucks. Right-hand spiral fluting clears chips efficiently during through-hole and blind-hole operations. The oxide finish provides a baseline level of lubricity and corrosion resistance for shop and field use.

Key Features

• 118-degree standard point angle for general-purpose entry into a broad range of materials
• High-speed steel construction with oxide coating for added surface hardness and lubricity
• Web-thinned tapered web reduces drilling thrust and improves chip flow
• Straight cylindrical shank compatible with standard drill chucks

Compatibility

Designed as a general-purpose jobber-length drill bit in the Cleveland 2001G series, compatible with any standard drill chuck accepting a 0.4688-inch straight cylindrical shank.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade professionals using a corded or cordless drill or drill press with an appropriately sized chuck. Secure the shank fully in the chuck before drilling and verify workpiece is clamped or fixtured to prevent rotation. Use cutting fluid or lubricant when drilling ferrous metals to extend tool life. Do not exceed the recommended speed range for the material being drilled.
