Cleveland C16596 Cobalt Jobber Drill Bit 6.5 Mm

Product Description

The CLEVELAND C16596 is a cobalt jobber-length drill bit designed for demanding metal-cutting applications. Built from M42 cobalt high-speed steel with a gold oxide coating, this bit maintains cutting edge integrity at elevated temperatures generated during heavy-duty drilling. The 135-degree split point reduces walking on entry and lowers the thrust needed to initiate a cut. With an overall length of 3.976 inches and a parabolic flute design, it clears chips efficiently across the full depth of cut. Machinists, maintenance technicians, and fabricators working with tough ferrous and non-ferrous materials will find this bit suited to production and repair work alike.

This drill bit is intended for use in ferrous and non-ferrous metals including cast iron, stainless steel, carbon steel, and non-ferrous alloys. Its M42 cobalt composition and heavy-duty grade rating make it appropriate for shop floor, field fabrication, and maintenance applications where standard high-speed steel bits lose their edge prematurely. The straight-cylindrical shank is compatible with standard three-jaw chucks on drill presses, hand drills, and milling machine setups. It is sold individually and suited for both production drilling and single-task repair scenarios.

Key Features

• M42 cobalt steel construction provides heat resistance and edge retention in hard metals
• 135-degree split point reduces bit walking and decreases required entry thrust
• Parabolic flute geometry promotes aggressive chip evacuation and reduces packing in deep holes
• Gold oxide finish improves lubricity and adds a layer of surface protection
• Web-thinned tapered web reduces cutting resistance and improves penetration rate
• Conforms to ASME B94.11M and DIN 338 standards for consistent dimensional accuracy

Compatibility

Designed for drilling cast iron, non-ferrous metals, stainless steel, and carbon steel. The 0.2559-inch straight-cylindrical shank fits standard three-jaw drill chucks. Conforms to DIN 338 and ASME B94.11M specifications.

Installation Notes

Install the shank fully into the chuck and tighten securely before operation. Power down and lock out the drill press or machine before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel or hard alloys to extend tool life, even though this bit does not support coolant-through delivery. Operators should follow applicable OSHA machine guarding and personal protective equipment requirements during use.
