Cleveland C14680 Cobalt Screw Machine Drill Bit Letter P

Product Description

The CLEVELAND C14680 is a cobalt screw machine length drill bit sized at Letter P (0.3230 inches) with a 135-degree split point and web-thinned geometry. Designed for heavy-duty drilling applications, this bit features a 2-flute right-hand spiral flute configuration and a straight-cylindrical shank. The M42 cobalt construction provides heat and wear resistance when drilling tough materials. With an overall length of 2-15/16 inches and a flute length of 1-11/16 inches, this compact stub-length bit is suited for high-torque, close-tolerance work in production and maintenance environments.

This drill bit is intended for use in alloy steel, aluminum, and similar materials where heat buildup and tool wear are concerns. The screw machine length format makes it well-suited for CNC machining centers, drill presses, and manual lathes where rigidity and reduced deflection are priorities. It is commonly used by machinists, tool-and-die technicians, and maintenance mechanics working in manufacturing, fabrication, and industrial maintenance settings.

Key Features

• Letter P size — 0.3230 inches decimal equivalent for precise hole sizing
• M42 cobalt construction rated for heavy-duty use in alloy and aluminum workpieces
• 135-degree split point with web thinning for reduced thrust and self-centering entry
• Screw machine (stub) length at 2-15/16 inches overall for maximum rigidity and minimal deflection
• Right-hand cut with regular spiral and parallel web for consistent chip evacuation
• Meets ASME B94.11M and DIN 1897 standards for dimensional and performance compliance

Compatibility

Designed as an OEM-style replacement or direct-use screw machine drill bit compatible with standard straight-shank drill chucks and collet systems accepting a 0.3230-inch shank diameter. Part of Cleveland Series 2133.

Installation Notes

Install in a compatible drill chuck or collet rated for the 0.3230-inch straight-cylindrical shank and secure firmly before operation. Power down all equipment completely before changing bits. Use appropriate cutting fluid for the workpiece material to maximize tool life and hole quality. Follow applicable shop safety standards and machine manufacturer guidelines during setup and operation.
