Cleveland C70200 Cobalt Drill Bit Wire 67 0.032 in

Product Description

The CLEVELAND C70200 is a cobalt jobber-length drill bit designed for precision drilling in demanding trade and industrial applications. Manufactured from M42 cobalt high-speed steel with a gold oxide coating, this bit delivers extended tool life in tough materials. It carries a wire gauge size of 67, which corresponds to a decimal diameter of 0.0320 inches, and features a 135-degree split point for fast penetration and reduced walking on entry. The straight-cylindrical shank seats securely in standard chucks. Two spiral flutes clear chips efficiently during cutting. This bit meets NAS 907 Type J standards and is rated heavy duty.

The C70200 is sized for fine-diameter work typically encountered in light metalworking, sheet metal fabrication, and precision mechanical assembly. Its 0.5-inch flute length and 1-3/8-inch overall length suit it for shallow-hole operations in aluminum and similar non-ferrous materials. Machinists, millwrights, sheet metal workers, and industrial maintenance technicians are the primary users. The web-thinned, tapered web construction reduces thrust requirements and improves centering without a center punch in many setups.

Key Features

• M42 cobalt steel construction for heat resistance and extended wear life
• Gold oxide coating reduces friction and improves chip evacuation
• 135-degree split point reduces entry force and minimizes bit walking
• Web-thinned tapered web lowers drilling thrust on light-gauge stock
• Right-hand cut with regular spiral flutes for consistent chip flow
• Meets NAS 907 Type J specification for dimensional conformance

Compatibility

Designed as a jobber-length replacement or production drill bit for applications requiring a wire size 67 diameter of 0.0320 inches, with primary suitability for aluminum and non-ferrous workpiece materials per supplier specification.

Installation Notes

Install in a compatible drill press, hand drill, or CNC spindle chuck rated for the 0.0320-inch straight-cylindrical shank diameter. Confirm chuck runout is within tolerance before use, as small-diameter bits are sensitive to misalignment. Apply cutting fluid appropriate for the workpiece material to preserve coating life. Never force a dull bit — replace at first sign of squealing, overheating, or off-diameter holes.
