Cleveland C02980 Jobber Drill Bit No. 36 Hss 118 Deg

Product Description

The CLEVELAND C02980 is a wire gauge No. 36 jobber length drill bit designed for general-purpose drilling in metal, aluminum, and similar materials. Machined from high speed steel with a bright, uncoated finish, it features a 118-degree standard point angle and a fast spiral flute geometry that promotes efficient chip evacuation. The straight-cylindrical shank measures 0.1065 inches in diameter for standard chuck compatibility. With an overall length of 2.5 inches and a flute length of 1.4375 inches, this bit is sized for use in benchtop drill presses, hand drills, and CNC drilling operations where wire gauge hole sizing is required. It is produced to ASME B94.11M standards and carries an ANSI specification designation.

This bit is suited for drilling aluminum as its primary workpiece material, though its general-purpose grade makes it appropriate for a broad range of softer metals and plastics encountered in fabrication, maintenance, and assembly work. The web-thinned, tapered web configuration reduces thrust requirements at the point and improves centering on entry. It is a single-piece per package item in the Cleveland Series 2012 lineup and is typically purchased by machinists, maintenance technicians, and metalworking tradespeople who require precise wire gauge hole sizes for tapping, reaming prep, or close-tolerance through-hole work.

Key Features

• Wire gauge No. 36 size — 0.1065 inches decimal equivalent for precise hole sizing
• High speed steel construction for durability across repeated use in metals and plastics
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Fast spiral flute geometry promotes efficient chip clearing during drilling
• Bright uncoated finish — no coating buildup that could alter diameter tolerance
• Meets ASME B94.11M standard; ANSI specification designation
• Diameter tolerance of -0.0005 to 0.0000 inches for consistent, repeatable hole quality

Compatibility

Designed as an OEM-style jobber length drill bit for use in standard 3-jaw drill chucks, collet systems, and drill press fixtures that accept straight-cylindrical shanks at 0.1065 inches diameter; compatible with hand drills, benchtop presses, and light-duty CNC equipment calling for wire gauge No. 36 tooling.

Installation Notes

This bit is installed by machinists and metalworking technicians using standard chuck tightening procedures — ensure the shank is fully seated and the chuck is tightened securely before operation. Secure the workpiece to prevent rotation during drilling, particularly in thin-material or small-diameter applications. Do not exceed the recommended feed rate for the material being drilled, and use cutting fluid when drilling steel or harder alloys to extend tool life. Inspect the drill point for wear or chipping before each use; a damaged point will produce oversized or off-center holes.
