Cleveland C14302 Screw Machine Drill Bit Letter V Cobalt

Product Description

The CLEVELAND C14302 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Sized at Letter V (0.3770 inches), this bit is manufactured from M42 cobalt high-speed steel and features a 135-degree split point that reduces walking and allows drilling to begin without a center punch. The parabolic flute geometry promotes efficient chip evacuation, and the web-thinned, parallel web configuration reduces thrust load. At 3.25 inches overall length, the stubby screw machine profile provides rigidity in drill press and CNC applications where flex and deflection must be minimized.

This bit is suited for drilling alloy steels and aluminum in production machining environments, including job shops, fabrication facilities, and maintenance operations. The right-hand cutting direction and straight cylindrical shank allow direct chucking in standard drill chucks and collet holders. The 1.875-inch flute length and 1.375-inch shank length are consistent with ASME B94.11M screw machine length standards. Licensed machinists, toolroom technicians, and CNC operators working with hard alloys will find this bit appropriate for high-duty-cycle use.

Key Features

• M42 cobalt steel construction for heat resistance and extended tool life in hard materials
• 135-degree split point reduces thrust and eliminates the need for center-punch spotting
• Parabolic flute geometry promotes fast chip evacuation and reduces recutting
• Web-thinned parallel web lowers drilling thrust in alloy and work-hardened steels
• Screw machine length profile provides rigidity for accurate, low-deflection drilling
• Meets ASME B94.11M dimensional standards; ANSI specification designation

Compatibility

Designed for use in standard drill chucks and collet systems accepting a 0.3770-inch straight cylindrical shank. Suited for drilling alloy steel and aluminum workpieces. Conforms to ASME B94.11M screw machine length specifications.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with cutting tool selection and setup. Secure the shank fully in the chuck or collet before operation and verify runout before starting a production run. Match spindle speed and feed rate to the workpiece material and consult the manufacturer cutting data for cobalt tooling in alloy steels. Do not use this bit in hammer drill mode; it is designed for rotary drilling only.
