Cleveland C70114 Jobber Length Drill Bit 6.8 Mm Cobalt

Product Description

The CLEVELAND C70114 is a jobber-length twist drill bit designed for precision drilling in metalworking and fabrication applications. Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit delivers extended tool life when drilling through aluminum, non-ferrous metals, and other demanding materials. The split point geometry at 135 degrees reduces walking on entry and lowers thrust requirements at the start of the cut. At 4.29 inches overall length with a 2.717-inch flute length, it fits standard drill chucks in both handheld and machine-mounted setups. This is a heavy-duty grade bit suited for trades professionals and machinists requiring consistent hole quality and dimensional accuracy.

The C70114 is intended for use in light-to-heavy fabrication environments where aluminum and similar workpiece materials are common. The straight cylindrical shank at 0.2677 inches in diameter accepts standard three-jaw drill chucks without adapters. With a regular spiral flute and right-hand cutting direction, it is compatible with conventional drill presses, CNC machining centers, and portable power drills. No coolant-through capability is required. This bit conforms to NAS 907 Type J standards, making it appropriate for aerospace-adjacent and precision manufacturing workflows where specification compliance matters.

Key Features

• M42 cobalt steel construction for heat resistance and extended tool life in abrasive materials
• Gold oxide coating reduces friction and provides visual wear indication
• 135-degree split point reduces thrust and prevents bit walking on entry
• Web-thinned, tapered web configuration improves chip evacuation
• Right-hand spiral flute with regular helix for consistent chip flow
• Meets NAS 907 Type J specification for precision and aerospace fabrication use

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard drill chucks accepting a 0.2677-inch straight cylindrical shank, compatible with drill presses, machining centers, and portable drills used in metalworking and fabrication trades.

Installation Notes

Install into a properly sized drill chuck and tighten securely before use. Power down and de-energize the drill or machine before changing bits. Use appropriate cutting fluid or lubricant when drilling metals to reduce heat buildup and extend bit life, even though this bit does not have coolant-through capability. Inspect the cutting edges for wear before each use, and replace when the split point or flute geometry shows signs of dulling.
