Cleveland C16541 Jobber Drill Bit Wire 39 Cobalt

Product Description

The CLEVELAND C16541 is a jobber-length drill bit sized at wire gauge 39 (0.0995 inches decimal), designed for heavy-duty drilling applications in demanding materials. Built from M42 cobalt high-speed steel with a gold oxide coating, this bit delivers extended tool life under high-heat conditions. The 135-degree split point starts on contact without a center punch and reduces walking on hard surfaces. A parabolic flute geometry improves chip evacuation and allows for faster feed rates. The straight-cylindrical shank is compatible with standard drill chucks. This bit is intended for use by machinists, maintenance technicians, pipefitters, and other trades requiring precise small-diameter hole drilling.

The C16541 is suited for drilling cast iron, stainless steel, carbon steel, and non-ferrous metals in both production and maintenance environments. Its 2-3/8-inch overall length fits standard jobber-length drill chuck clearances. The 1-3/8-inch flute length accommodates typical hole depths for this diameter range. This bit performs in manual drill presses, CNC machines, and portable electric drills where a short, rigid setup is appropriate for the 0.0995-inch diameter.

Key Features

• M42 cobalt steel construction for heat resistance and extended cutting life in hard and abrasive materials
• 135-degree split point for self-centering starts and reduced thrust force
• Gold oxide coating reduces friction and provides surface protection
• Parabolic flute design improves chip clearance and allows higher feed rates
• Web-thinned tapered web reduces cutting resistance without sacrificing rigidity
• Meets ASME B94.11M and DIN 338 standards

Compatibility

Designed as a heavy-duty OEM-style jobber-length drill bit rated for cast iron, non-ferrous metal, stainless steel, and steel workpieces per Series 2075 specifications.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotary cutting tools. Secure the straight-cylindrical shank firmly in a properly sized drill chuck before operation. Always wear appropriate eye protection and ensure the workpiece is clamped securely before drilling. Do not exceed the recommended speed and feed ranges for the workpiece material and drill diameter.
