Cleveland C14206 Screw Machine Drill Bit 5/32 in Cobalt

Product Description

The CLEVELAND C14206 is a screw machine length cobalt drill bit designed for high-performance drilling in demanding materials. Built to ASME B94.11M standards, it features a 135-degree split point that starts on contact without a center punch and reduces walking on hard surfaces. The parabolic flute geometry improves chip evacuation and reduces heat buildup during drilling. At 2-1/16 inches overall length, the stub-style body provides rigidity in short-reach applications. The M42 cobalt material grade makes this bit well-suited for drilling alloy steels, stainless steel, and aluminum where standard high-speed steel bits would dull prematurely. Licensed tradespeople and production machinists are the primary installers of this tool.

This bit is intended for use in drill presses, CNC machining centers, hand-held power drills, and screw machine setups where a compact, rigid cutting tool is required. Its 5/32-inch diameter and straight-cylindrical shank make it compatible with standard three-jaw chucks and collet holders of matching bore. Primary workpiece materials listed by the manufacturer include alloy steel and aluminum. The web-thinned, parallel web configuration reduces thrust requirements, which is especially useful when drilling work-hardened or tough alloy materials in production or service environments.

Key Features

• M42 cobalt construction for heat resistance and extended tool life in alloy and hardened materials
• 135-degree split point starts on contact and reduces drill walking without a pilot hole
• Parabolic flute design promotes fast chip evacuation and reduces cutting friction
• Web-thinned parallel web lowers axial thrust, reducing operator fatigue and machine load
• Screw machine (stub) length provides added rigidity compared to jobber-length bits
• Meets ASME B94.11M and ANSI specification designation for dimensional consistency

Compatibility

Designed for use with standard drill chucks and collet systems accepting a 0.1562-inch straight-cylindrical shank. Primary workpiece materials per manufacturer specification are alloy steel and aluminum. Part of the CLEVELAND Series 2175 heavy-duty cobalt screw machine drill line.

Installation Notes

Install and remove drill bits only with the drill press or power tool fully powered off and the chuck key removed from the chuck. Secure the workpiece firmly before drilling to prevent rotation or movement during the cut. Use appropriate cutting fluid or coolant when drilling alloy steels to extend tool life, noting that this bit does not have coolant-through capability. Follow applicable ANSI and shop safety standards for rotating cutting tools, including proper eye protection and guarding.
