Cleveland C15096 Screw Machine Drill Bit Size 6 Cobalt

Product Description

The CLEVELAND C15096 is a screw machine length drill bit designed for high-performance drilling in alloy steels, aluminum, and other demanding workpiece materials. Built from M42 cobalt high-speed steel, this bit handles heat and wear better than standard HSS tooling, making it a reliable choice for production environments and tough-material applications. The 135-degree split point reduces thrust and starts on contact without center-punching. The parabolic flute geometry improves chip evacuation and reduces heat buildup in the cut zone. Wire size 6 equates to 0.2040 inches in decimal. Overall length is 2.375 inches, keeping the bit rigid and minimizing deflection in short-reach setups.

This drill bit is suited for machine shop production drilling, CNC operations, and handheld drill press work where a short, stiff bit is preferred over jobber length. The screw machine length profile reduces chatter and improves hole accuracy in materials such as alloy steel and aluminum. The straight cylindrical shank is compatible with standard drill chucks and collet systems. Flute length is 1.25 inches, and the shank length is 1.125 inches. Applications include tapping pilot holes, through-holes in structural components, and repetitive production drilling cycles requiring consistent diameter tolerance.

Key Features

• M42 cobalt construction for extended tool life in abrasive and heat-generating materials
• 135-degree split point reduces entry thrust and eliminates the need for center-punching
• Parabolic flute geometry promotes faster chip evacuation and cooler cutting
• Web-thinned parallel web configuration reduces cutting resistance at the chisel edge
• Screw machine length body provides added rigidity and reduced deflection versus jobber length
• Diameter tolerance of +0.0000 to -0.0007 inches meets ASME B94.11M standards

Compatibility

Designed for use in standard drill chucks and collet holders accepting a 0.2040-inch straight cylindrical shank. Rated for primary workpiece materials including alloy steel and aluminum per Series 2175A specifications.

Installation Notes

This bit is installed by a machinist or tool and die professional in a drill press, CNC machining center, or hand drill with an appropriate chuck. Ensure the shank is fully seated and the chuck is tightened before operation. Use appropriate cutting fluid for alloy steel applications to extend tool life and maintain hole tolerance. Inspect the cutting edges and split point for wear before each use in production runs.
