Cleveland C15095 Cobalt Screw Machine Drill Bit Size 5

Product Description

The CLEVELAND C15095 is a cobalt screw machine length drill bit designed for high-speed drilling in tough materials. Built to Series 2175A specifications, it carries a wire gauge size of 5, equal to 0.2055 inches in decimal diameter, and features a 135-degree split point with web thinning for fast, accurate starts without a center punch. The parabolic flute geometry improves chip evacuation in deeper holes. At 2.375 inches overall length, this short-body stub drill fits low-clearance setups in drill presses, CNC machines, and production line fixtures. Licensed machinists, tool-and-die shops, and metalworking professionals are the primary users.

This bit is suited for production drilling in alloy steel, aluminum, and similar workpiece materials where heat resistance and edge retention are priorities. The screw machine length format keeps the bit rigid in tight-clearance applications, including turret lathes, gang drills, and bench-top drill presses. The straight-cylindrical shank seats directly in standard drill chucks without an adapter. Cobalt-grade M42 construction holds up under the elevated temperatures generated during continuous-duty metal cutting.

Key Features

• Wire size 5 diameter: 0.2055 inches, tolerance +0.0000 to -0.0007 inches per ASME B94.11M
• M42 cobalt construction for heat resistance and extended tool life in alloy and aluminum drilling
• 135-degree split point with web thinning reduces thrust and eliminates the need for a center punch
• Parabolic flute profile promotes efficient chip clearance during deep-hole passes
• Screw machine length body at 2.375 inches overall for maximum rigidity in low-clearance setups
• Right-hand cut, straight-cylindrical shank fits standard 3-jaw and keyed drill chucks

Compatibility

Designed as an OEM-style replacement and standard production drill bit for metalworking applications requiring a wire size 5 screw machine length drill, conforming to ASME B94.11M and ANSI specification designation.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking tradespeople familiar with cutting tool selection and machine setup. Secure the shank fully in the drill chuck and verify runout before drilling. Always power down and lock out the machine before changing bits. Do not exceed the recommended RPM range for the workpiece material and bit diameter as published in standard machining data references.
