Cleveland C16512 Cobalt Jobber Drill Bit Wire Size 10

Product Description

The CLEVELAND C16512 is a cobalt jobber length drill bit designed for demanding metal-cutting applications in professional trade environments. Manufactured from M42 cobalt high-speed steel, it carries a gold oxide coating that improves heat resistance and extends tool life under high-speed drilling conditions. The bit features a 135-degree split point for fast, self-centering starts without a center punch, paired with a parabolic flute geometry that efficiently evacuates chips and reduces heat buildup. At 0.1935 inches in diameter (wire size 10) with a 3-5/8 inch overall length, this is a heavy-duty tool rated for sustained production drilling.

This drill bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and carbon steel in both shop and field settings. The straight-cylindrical shank seats securely in standard keyed or keyless drill chucks. Machinists, pipefitters, fabricators, and industrial maintenance technicians working with hard or abrasive materials will find the M42 cobalt construction appropriate for the task. The parabolic flute design supports higher feed rates compared to standard jobber geometry, making it a practical choice for repetitive hole operations on ferrous and non-ferrous workpieces.

Key Features

• M42 cobalt high-speed steel construction rated for heavy-duty drilling in hard metals
• 135-degree split point self-centers on the workpiece and reduces thrust force required
• Parabolic flute design accelerates chip evacuation and reduces heat in the cut zone
• Gold oxide finish improves lubricity and provides additional heat resistance
• Web-thinned tapered web maintains rigidity while reducing cutting resistance
• Meets ASME B94.11M and DIN 338 standards for jobber length drill bits

Compatibility

Designed for use in any standard drill chuck accepting a 0.1935 inch straight-cylindrical shank. Rated for drilling cast iron, non-ferrous metal, stainless steel, and steel workpieces. Belongs to Cleveland Series 2075, sized within the 0.1500 to 0.2000 inch decimal inch drill bit range.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard bench drill presses, CNC machining centers, or handheld power drills with appropriate chuck capacity. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for the application. Apply cutting fluid or coolant appropriate to the workpiece material to maximize tool life, particularly when drilling stainless steel or cast iron. This bit does not support coolant-through delivery; external coolant application only.
