Cleveland C16709 Cobalt Drill Bit 6.8 Mm Tin Coated

Product Description

The CLEVELAND C16709 is a jobber-length drill bit engineered for heavy-duty metal drilling applications. Built from M42 cobalt high-speed steel and finished with a Titanium Nitride (TiN) coating, it delivers extended tool life and heat resistance in demanding production and maintenance environments. The bit measures 4.291 inches overall length with a 135-degree split point that reduces walking and allows drilling to start without a center punch. A parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup and the risk of chip packing in deep-hole operations. HVAC technicians, pipefitters, and maintenance machinists working with hard metals will find this bit well-suited to their workflow.

This drill bit is designed for right-hand cutting in materials that benefit from cobalt tooling, including stainless steel, cast iron, high-alloy steels, and work-hardened materials commonly encountered in mechanical and industrial trade settings. The straight-cylindrical shank at 0.2677 inches diameter is compatible with standard drill chucks. The parabolic flute and web-thinned, tapered-web construction make it particularly effective for through-hole drilling in sheet metal and structural steel used in HVAC fabrication, piping support work, and equipment installation.

Key Features

• M42 cobalt steel construction for heat resistance and durability in hard-metal drilling
• Titanium Nitride (TiN) coating extends cutting life and reduces friction
• 135-degree split point reduces bit walking and lowers required thrust force
• Parabolic flute design improves chip evacuation in deep-hole applications
• Web-thinned tapered web reduces cutting resistance at the drill tip
• Meets ASME B94.11M and DIN 338 standards

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for standard drill chucks accepting a 0.2677-inch straight-cylindrical shank, compatible with handheld drills, drill presses, and CNC drilling setups used in mechanical, HVAC, and plumbing trade applications.

Installation Notes

Installation should be performed by qualified tradespeople familiar with rotating cutting tools and machine shop safety practices. Ensure the drill chuck is fully secured and the workpiece is clamped before operation. Use appropriate cutting fluid or coolant when drilling hard alloys to preserve coating integrity and bit life. Follow applicable OSHA machine guarding requirements when operating drill presses or power tools on the job site.
