Cleveland C16707 Cobalt Jobber Drill Bit 6 Mm

Product Description

The CLEVELAND C16707 is a cobalt jobber-length drill bit designed for cutting ferrous metals, stainless steel, and other hard materials encountered in heavy-duty machining and fabrication work. Built from M42 cobalt high-speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and heat resistance under sustained load. The 135-degree split point reduces walking on entry and lowers thrust requirements compared to standard 118-degree geometry. With an overall length of 3.661 inches and a 6 mm diameter (0.2362 inches), this bit fits standard drill chucks and machine spindles used across metalworking trades.

This bit is suited for machinists, tool-and-die workers, pipefitters, and maintenance technicians drilling through structural steel, stainless, and alloy materials in both shop and field settings. The parabolic flute geometry promotes efficient chip evacuation during deep-hole drilling, reducing the need for peck cycles. The straight-cylindrical shank seats securely in Jacobs-style chucks and machine collets. It is sold individually and is appropriate for hand-held drill use as well as drill press and CNC operations where a DIN 338 jobber-length bit is specified.

Key Features

• M42 cobalt HSS construction for high heat and wear resistance in hard metals
• TiN coating extends cutting edge life and reduces friction
• 135-degree split point starts on contact and reduces drill walking
• Parabolic flute design promotes fast, reliable chip clearance
• Web-thinned, tapered web configuration lowers cutting resistance
• Meets ASME B94.11M and DIN 338 standards for jobber-length drills

Compatibility

Designed as an OEM-style replacement or standard tooling selection for applications requiring a DIN 338 jobber-length cobalt drill bit in the 6 mm diameter class with a straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with metal drilling operations. Secure the shank fully in the chuck or collet before operation and verify runout before drilling into workpieces. Always wear appropriate PPE including eye protection when operating drill bits. Do not exceed the recommended feed and speed ratings for the workpiece material and bit diameter.
