Cleveland C71081 Jobber Drill Bit 7.14mm Hss Oxide

Product Description

The CLEVELAND C71081 is a jobber-length twist drill bit designed for general-purpose metal drilling in production and maintenance applications. Built from high speed steel with an oxide coating, it delivers adequate hardness and surface protection for drilling steel, cast iron, and similar materials. The bit measures 7.14 mm (0.2812 inches) in diameter with a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation at entry. Overall length is 4.25 inches with a flute length of 2-15/16 inches. This is a straight-cylindrical shank bit sized at 0.2812 inches, compatible with standard drill chucks. Licensed machinists, millwrights, and general trade mechanics are the primary users.

The C71081 fits residential and light commercial maintenance, fabrication shops, and field service work where a reliable general-purpose drill bit is needed. It is suited for drilling ferrous and non-ferrous metals, plastics, and wood composites. The regular spiral flute geometry and 4xD flute-to-diameter ratio make it appropriate for through-hole and blind-hole operations in a wide range of material thicknesses. It is sold individually and is part of the Cleveland 2001G series.

Key Features

• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction with oxide coating for surface protection and heat resistance
• Regular spiral, two-flute design promotes efficient chip removal
• Straight-cylindrical shank at 0.2812 inches fits standard drill chucks without adapters
• Meets ASME B94.11M and DIN 338 standards for jobber-length drill bits
• Diameter tolerance of -0.0010 to 0.0000 inches ensures accurate hole sizing

Compatibility

Designed as an OEM-style general-purpose jobber-length drill bit in the Cleveland 2001G series, suitable for use in any standard drill chuck accepting a 0.2812-inch straight-cylindrical shank.

Installation Notes

This bit is installed by a qualified machinist or trade mechanic using a hand drill, drill press, or milling machine with a compatible chuck. Secure the shank fully in the chuck and verify concentricity before drilling. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear or chipping before each use and replace when point geometry is degraded.
