Cleveland C03111 Jobber Drill Bit Letter P 0.3230 in Hss

Product Description

The CLEVELAND C03111 is a jobber-length drill bit sized to letter P, equivalent to 0.3230 inches in decimal diameter. Made from high speed steel with a bright, uncoated finish, it features a 118-degree standard point angle and a fast spiral flute configuration for efficient chip evacuation. The tapered web with web thinning reduces thrust requirements at the point, making it well suited for production and maintenance drilling applications. A straight-cylindrical shank allows it to seat directly in standard drill chucks without adapters. This bit meets ASME B94.11M standards and is classified as a general-purpose, ANSI-specification tool.

The C03111 is intended for use in drilling aluminum as its primary workpiece material, though its general-purpose grade makes it a practical choice across a broad range of softer metals and materials encountered in trade and light industrial work. The right-hand cut, two-flute spiral design is compatible with conventional drill presses, hand drills, and CNC drilling operations. With an overall length of 4.625 inches and a flute length of 3.313 inches, it fits within the standard jobber-length envelope used in most shop and field drilling setups.

Installation Notes

Installation and use should be performed by machinists, maintenance technicians, or qualified tradespeople familiar with rotating cutting tools. Secure the shank fully in the chuck and verify concentricity before running at speed. Always power down and lock out the drilling machine before changing bits. Appropriate eye protection and chip guards should be in place during operation per applicable shop safety standards.
