Cleveland C16718 10mm Cobalt Jobber Drill Bit Tin

Product Description

The CLEVELAND C16718 is a jobber-length drill bit designed for heavy-duty metal drilling applications. Built from M42 cobalt high-speed steel and coated with titanium nitride (TiN), it delivers extended tool life and heat resistance in demanding cutting conditions. The bit measures 10 mm (0.3937 inches) in diameter with a 5.236-inch overall length and a 3.425-inch flute length. A 135-degree split point reduces walking and allows drilling to begin without a center punch on most metallic surfaces. Licensed HVAC, plumbing, electrical, and mechanical trades install this bit when working with steel pipe, sheet metal, structural members, and equipment frames.

This bit is suited for professional trade applications involving ferrous and non-ferrous metals. The parabolic flute geometry improves chip evacuation during deep-hole drilling, reducing heat buildup and the need for frequent retraction. It conforms to DIN 338 specification and carries a straight-cylindrical shank compatible with standard drill chucks. It falls within the 0.3500 to 0.4000 inch drill bit size range and is graded as a heavy-duty tool appropriate for production and service environments.

Key Features

• M42 cobalt construction for high heat resistance in hard metals
• TiN coating reduces friction and extends cutting edge life
• 135-degree split point for self-centering starts and reduced thrust
• Parabolic flute design improves chip removal in deep-hole applications
• Web-thinned, tapered web for reduced feed pressure
• Conforms to DIN 338 specification for consistent dimensional accuracy

Compatibility

Designed as a heavy-duty jobber-length drill bit conforming to DIN 338, compatible with any standard drill chuck accepting a 0.3937-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified trade professionals familiar with metalworking practices. Secure the workpiece firmly before drilling and confirm the drill chuck is properly tightened to the shank. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
