Cleveland C03673 3/8 Inch Hss Jobber Drill Bit 118 Deg

Product Description

The CLEVELAND C03673 is a jobber-length twist drill bit designed for general-purpose drilling in metal, aluminum, and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable cutting performance without added coating costs. The bit features a 118-degree standard point angle, a slow-spiral flute geometry, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. At 5 inches overall length with a 3-5/8-inch flute length, it fits standard drill chucks and magnetic drill presses. This is a Series 2020 bit manufactured to ASME B94.11M standards.

The C03673 is suited for drilling through aluminum, soft steel, and general fabrication materials in residential and light commercial trade applications. HVAC techs, plumbers, electricians, and sheet metal workers will find it at home in standard pistol-grip drills and drill presses. Its 3/8-inch straight-cylindrical shank seats directly in 3/8-inch or larger keyed and keyless chucks without adapters. Right-hand cut geometry works with standard clockwise-rotation drills.

Key Features

• 3/8-inch diameter with a diameter tolerance of -0.0010 to 0.0000 inches for accurate hole sizing
• 118-degree standard point angle suited for general-purpose and aluminum drilling
• Slow-spiral, 2-flute design promotes chip clearance and reduces heat buildup
• Web-thinned tapered web lowers drilling thrust and extends bit life
• Bright uncoated finish — no coating buildup to interfere with tight-tolerance holes
• Conforms to ASME B94.11M and ANSI specification designation

Compatibility

Designed as a general-purpose OEM-style jobber drill bit compatible with any standard 3/8-inch or larger keyed or keyless drill chuck accepting straight-cylindrical shanks.

Installation Notes

Install the bit securely in a properly rated drill chuck before operation. Use appropriate cutting fluid or lubricant when drilling ferrous materials to reduce heat and prolong bit life. Secure the workpiece firmly before drilling to prevent rotation or movement. Always wear appropriate eye protection and follow applicable OSHA safety guidelines for drilling operations.
