Cleveland C16650 Jobber Drill Bit No 38 Cobalt Tin

Product Description

The CLEVELAND C16650 is a jobber-length drill bit designed for heavy-duty metal drilling in professional trade and industrial applications. Built from M42 cobalt high-speed steel with a titanium nitride (TiN) coating, this bit handles tough ferrous and non-ferrous materials with extended tool life. It carries a No. 38 wire gauge size with a decimal diameter of 0.1015 inches, a 135-degree split point for fast self-centering starts without a center punch, and a parabolic flute geometry that efficiently evacuates chips during deep-hole drilling. This bit is intended for use by machinists, maintenance technicians, and trade professionals requiring precision small-diameter drilling.

The C16650 is suited for production and maintenance drilling in steel, stainless, cast iron, and hard alloys. Its straight-cylindrical shank seats securely in standard drill chucks, collets, and drill press spindles. The 2.5-inch overall length and 1-7/16-inch flute length make it appropriate for general-purpose hole-making in plate, structural stock, and fabricated assemblies. It is sold and packaged individually.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance in hard materials
• Titanium nitride (TiN) coating reduces friction and extends cutting life
• 135-degree split point eliminates walking and reduces thrust force on entry
• Parabolic flute profile improves chip evacuation in deep or interrupted cuts
• Web-thinned tapered web for reduced cutting resistance and improved hole accuracy
• Meets ASME B94.11M and DIN 338 standards for jobber-length drill bits

Compatibility

Designed as a standard jobber-length drill bit with a straight-cylindrical shank compatible with conventional three-jaw drill chucks, collet systems, and drill press spindles accepting 0.1015-inch shank diameter tooling.

Installation Notes

This bit is installed by machinists and maintenance technicians using standard drill presses, hand drills, or milling machines. Ensure the shank is fully seated and securely clamped in the chuck or collet before operation. Use appropriate cutting fluid or lubricant when drilling hard alloys or stainless steel to manage heat buildup and prolong bit life. Inspect the cutting edges for wear or chipping before each use and replace when diameter tolerance can no longer be maintained.
