Cleveland C15140 Cobalt Drill Bit Letter K 9/32 Inch

Product Description

The CLEVELAND C15140 is a screw machine length drill bit designed for high-performance drilling in demanding production environments. Built from M42 cobalt high-speed steel, it carries a 135-degree split point with web thinning for fast penetration and reduced thrust. The bit measures 2-11/16 inches overall length with a 1-1/2 inch parabolic flute length, and features a straight-cylindrical shank with a diameter of 0.2810 inches. The parabolic flute geometry promotes efficient chip evacuation, making it well suited for interrupted cuts and deep-hole applications. It conforms to ASME B94.11M standards and carries an ANSI specification designation.

This drill bit is intended for use in screw machine operations and general production drilling. Primary workpiece materials include alloy steel and aluminum. The screw machine length profile fits standard drill chucks and quick-change toolholding systems used in CNC lathes, turret lathes, drill presses, and machining centers. The short, rigid body reduces deflection and improves hole location accuracy compared to jobber-length alternatives. It is a single-bit unit typically purchased by machinists, tool-and-die shops, and maintenance technicians requiring consistent hole quality in metalworking applications.

Key Features

• M42 cobalt construction for heat and wear resistance in alloy and aluminum drilling
• 135-degree split point with web thinning for self-centering and reduced entry thrust
• Parabolic flute geometry for efficient chip evacuation in deep or interrupted cuts
• Screw machine length body for added rigidity and improved hole location accuracy
• Straight-cylindrical shank compatible with standard drill chucks and quick-change holders
• Meets ASME B94.11M and ANSI specification requirements

Compatibility

Designed as an OEM-style replacement or direct tooling selection for screw machine and production drilling applications requiring a Letter K, 0.2810-inch diameter bit in the CLEVELAND Series 2175A line.

Installation Notes

Installation is performed by machinists and tooling technicians. Secure the shank fully in the drill chuck or collet before operation and verify runout is within acceptable limits. Confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the cut. Follow applicable shop safety procedures and machine guarding requirements when operating drilling equipment.
