Cleveland C72029 Jobber Drill Bit 29/64 Inch Hss

Product Description

The CLEVELAND C72029 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, plastic, and composite materials. Built from high speed steel with a bright uncoated finish, it features a standard 118-degree split point and a web-thinned, tapered web configuration that reduces thrust during entry and improves chip evacuation. The two-flute spiral design with regular spiral type provides consistent cutting action across a wide range of materials. At 29/64 inch (0.4531 inch decimal), it suits applications requiring a precise, mid-range fractional bore size. Licensed tradespeople and machinists in HVAC, plumbing, and general mechanical trades will find this bit a reliable everyday tool.

The C72029 is suited for residential and light commercial trade work where accurate fractional-size holes are required in ferrous and non-ferrous metals, structural materials, and similar substrates. The 5-5/8-inch overall length and straight-cylindrical shank allow it to seat in standard three-jaw chucks on corded drills, drill presses, and magnetic base drills commonly found in field and shop settings. The bit conforms to ASME B94.11M and DIN 338 standards, making it appropriate for precision-critical installations.

Key Features

• Bright uncoated finish — no coating to chip or flake during regrinding
• Regular spiral, two-flute design promotes efficient chip clearance
• Straight-cylindrical shank fits standard three-jaw chucks without adapters
• Meets ASME B94.11M and DIN 338 dimensional and performance standards

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any three-jaw chuck accepting a 0.4531-inch straight-cylindrical shank, including corded drills, benchtop drill presses, and magnetic base drills.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with rotating-tool safety practices. Secure the workpiece firmly before drilling and verify chuck jaws are fully tightened on the shank. Disconnect power to the drill or press before changing bits. Apply appropriate cutting fluid when drilling hardened or ferrous stock to extend bit life and maintain dimensional tolerance.
