Cle-line C74015 Jobber Drill Bit 8.00 Mm Hss Split Point

Product Description

The CLE-LINE C74015 is an 8.00 mm high-speed steel jobber drill bit designed for production and maintenance drilling in steel and cast iron. It features a 135-degree split point that reduces walking and lowers thrust at the start of the cut. A black oxide and gold coating adds surface hardness and helps resist heat buildup during extended drilling operations. The right-hand spiral flute geometry evacuates chips efficiently along the full 2.95-inch flute length. Overall length is 4.61 inches. This bit meets ASME B94.11M and DIN 338 standards and is rated for heavy-duty, high-performance use by machinists, pipefitters, and maintenance technicians.

The C74015 is suited for drilling in ferrous metals including steel and cast iron in both shop and field environments. Its 0.32-inch decimal-inch equivalent diameter fits standard drill chucks used in drill presses, hand drills, and magnetic-base drills. The straight cylindrical shank with three flats allows secure seating in both keyed and keyless chucks. Typical applications include hole sizing for fasteners, conduit knockouts in steel panels, and structural fabrication work where consistent hole diameter tolerance is required.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill bit for standard drill chucks accepting a 0.32-inch straight cylindrical shank across drill presses, cordless and corded hand drills, and magnetic-base drilling units.

Installation Notes

Installation and use should be performed by a qualified machinist or trade professional familiar with rotary cutting tools. Secure the shank fully in the chuck and verify the bit runs true before cutting. Always wear eye protection and ensure the workpiece is clamped before drilling. Do not exceed the drill press or hand tool manufacturer rated RPM for the bit diameter in use.
