Cleveland C15106 Cobalt Screw Machine Drill Bit 16

Product Description

The CLEVELAND C15106 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built to ASME B94.11M standards, this wire gauge size 16 bit measures 0.1770 inches in diameter and features a 135-degree split point for fast, self-centering starts with minimal walking. The two-flute parabolic geometry promotes efficient chip evacuation, while the cobalt material grade M42 delivers heat resistance and extended tool life when cutting tough materials. At 2-3/16 inches overall length, the stub-style profile provides rigidity in drill press, CNC, and hand-tool setups. Licensed machinists, millwrights, and tool-and-die technicians are the primary users of this bit.

This bit is suited for drilling alloy steels and aluminum in production machining, fabrication shops, and maintenance environments. The screw machine length format is preferred when setup clearance is limited or when added rigidity over jobber-length bits is needed. The right-hand cut, straight cylindrical shank seats cleanly in standard drill chucks and collets without adapters. The parallel web configuration and web-thinned geometry reduce thrust requirements at the cutting tip, making it effective for hand-fed drilling operations as well as machine-fed cycles.

Key Features

• Cobalt M42 tool material for superior heat and wear resistance when drilling hard alloys
• 135-degree split point with web thinning for self-centering entry and reduced thrust
• Parabolic two-flute design for fast chip evacuation and cooler cutting
• Screw machine length (2-3/16 inches OAL) provides rigidity over standard jobber-length bits
• Right-hand cut, straight cylindrical shank fits standard drill chucks and collets
• Meets ASME B94.11M and ANSI specification designation for dimensional accuracy

Compatibility

Designed as a standard screw machine length drill bit with a 0.1770-inch straight cylindrical shank, compatible with drill presses, CNC machining centers, and hand drills accepting straight shank tooling in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Ensure the drill chuck or collet is fully tightened and the workpiece is securely fixtured before beginning any drilling operation. Always operate within the recommended speed and feed parameters for the workpiece material to prevent overheating. Wear appropriate eye and hand protection per shop safety standards.
