Cleveland C15115 Cobalt Screw Machine Drill Bit Size 25

Product Description

The CLEVELAND C15115 is a screw machine length drill bit designed for high-productivity drilling in demanding shop and field applications. Built from M42 cobalt high-speed steel with a coated finish, this bit handles tough materials including alloy steels and aluminum. It carries a wire gauge size of 25, corresponding to a decimal diameter of 0.1495 inches, and features a 135-degree split point with web thinning for fast penetration and reduced thrust. The parabolic flute geometry promotes efficient chip evacuation. Right-hand cut with a straight-cylindrical shank, the C15115 conforms to ASME B94.11M standards and is sold individually.

This drill bit is suited for screw machine operations, CNC drilling, and general-purpose metalworking where a stubby, rigid tool length is required. The reduced overall length of 2-1/16 inches minimizes deflection in tight setups and turret applications. It is a practical choice for machinists and metalworking tradespeople drilling alloy steel and aluminum in production or maintenance environments. Coolant-through is not supported on this model.

Key Features

• M42 cobalt steel construction for heat resistance and extended tool life in hard metals
• 135-degree split point with web thinning reduces walking and lowers required thrust
• Parabolic flute profile improves chip flow and reduces heat buildup
• Screw machine length (2-1/16 inches OAL) provides rigidity and minimizes deflection
• Right-hand cut, straight-cylindrical shank fits standard drill chucks and collets
• Meets ASME B94.11M standards; ANSI specification designation

Compatibility

Designed as an OEM-style screw machine length drill bit for use in standard drill chucks and collets accepting a 0.1495-inch straight-cylindrical shank, consistent with ASME B94.11M and ANSI specifications.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking tradespeople familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify shank seating and chuck tightness before initiating a cut. Operate within the recommended speed and feed range for the workpiece material to avoid premature tool wear or breakage.
