Cleveland C16568 Cobalt Drill Bit 17/64 in 135 Deg

Product Description

The CLEVELAND C16568 is a cobalt jobber length drill bit designed for demanding metal drilling applications in industrial and trade settings. Built to Series 2075 standards, this bit features a 135-degree split point for fast, accurate starts without center-punching and a parabolic flute geometry that promotes efficient chip evacuation. The M42 cobalt steel construction with a gold oxide coating delivers heat and wear resistance when drilling hard or abrasive materials. At 4-1/8 inches overall length with a 17/64-inch diameter, it fits standard drill chucks for bench, drill press, and hand-held power tool use. Machinists, pipefitters, and maintenance technicians are the typical users.

The C16568 is suited for drilling cast iron, stainless steel, carbon steel, and non-ferrous metals in both production shop and field maintenance environments. The parabolic flute design keeps chips moving out of the hole cleanly during deeper passes, reducing heat buildup and tool deflection. Right-hand cut geometry is standard for conventional drill press and CNC drill use. The straight-cylindrical shank seats securely in keyed or keyless chucks without slippage under normal feed loads.

Key Features

• M42 cobalt steel construction for high heat resistance in hard-metal drilling
• 135-degree split point reduces thrust and eliminates the need for center-punching
• Parabolic flute geometry accelerates chip removal and reduces packing in deep holes
• Gold oxide finish provides added lubricity and corrosion resistance
• Web-thinned, tapered web configuration maintains rigidity while reducing cutting resistance
• Meets ASME B94.11M and DIN 338 standards for jobber-length drill bits

Compatibility

Designed as a standard jobber-length replacement drill bit for use in any application requiring a 17/64-inch hole in cast iron, non-ferrous metal, stainless steel, or steel with a right-hand cutting drill.

Installation Notes

Installation is performed by machinists, maintenance technicians, or trade professionals using a drill press, hand drill, or CNC drilling machine. Secure the straight-cylindrical shank fully in the chuck before operation and verify chuck tightness. Power down and de-energize all equipment before changing bits. Do not exceed the recommended feed rate or spindle speed for the workpiece material, as cobalt bits can fracture under excessive lateral force.
