Cleveland C03097 Jobber Drill Bit Letter M Hss

Product Description

The CLEVELAND C03097 is a jobber-length drill bit sized to letter M (0.2950 inches) and manufactured from high-speed steel with a bright, uncoated finish. It features a 118-degree standard point angle with a web-thinned, tapered web for easier penetration and reduced thrust. The two-flute fast spiral design promotes efficient chip evacuation during drilling operations. With an overall length of 4.375 inches and a flute length of 3.0625 inches, the C03097 is suited to general-purpose hole-making tasks performed by machinists, maintenance technicians, and fabrication professionals.

This drill bit is built for general-purpose drilling in aluminum and similar non-ferrous materials, though the high-speed steel construction handles mild steel and plastics in typical shop and field conditions. The straight-cylindrical shank at 0.2950 inches diameter seats in standard three-jaw drill chucks without adapters. It conforms to ASME B94.11M and carries an ANSI specification designation, making it appropriate for production and maintenance environments where dimensional consistency is required. Sold individually.

Key Features

• Letter M size: 0.2950 inches diameter with a tight tolerance of -0.0010 to 0.0000 inches
• 118-degree standard point with web-thinned, tapered web for reduced entry thrust
• Fast-spiral, two-flute geometry for efficient chip clearing in aluminum and soft metals
• High-speed steel construction provides hardness and wear resistance for general-purpose drilling
• Bright uncoated finish — suitable for use with cutting fluids where needed
• Meets ASME B94.11M dimensional standards under ANSI specification

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck or drill press accepting a 0.2950-inch straight-cylindrical shank. Part of the Cleveland Series 2012 jobber-length line.

Installation Notes

A licensed machinist or qualified maintenance technician should secure the shank fully in a calibrated three-jaw chuck before use. Confirm the workpiece is clamped or fixtured and the machine is at an appropriate speed for the material and diameter. Apply cutting fluid when drilling steel to extend tool life. Inspect the point for chipping or dulling before each use and regrind or replace as needed to maintain dimensional accuracy.
