Cleveland C02945 Jobber Drill Bit Wire 51 Hss 118 Degree

Product Description

The CLEVELAND C02945 is a jobber-length twist drill bit sized to wire gauge number 51, with a decimal diameter of 0.0670 inches. Manufactured from high-speed steel (HSS) with a bright finish, it features a 118-degree standard point angle and a fast spiral flute for efficient chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. At 2 inches overall length with a 1-inch flute length, this bit is suited for general-purpose drilling in metal, plastic, and similar materials. It is installed and used by machinists, maintenance technicians, and trade professionals requiring precise small-diameter hole work.

This bit is designed for general-purpose drilling applications where tight-tolerance small-diameter holes are required. The wire size 51 designation makes it a common choice for tap-drill operations, pilot holes, and precision layout work in light metals, mild steel, and thermoplastics. The web-thinned, tapered-web geometry reduces thrust and improves centering at entry. It is compatible with standard handheld drills, drill presses, and CNC drilling setups that accept a 0.0670-inch straight shank. The bright coating preserves the HSS substrate without added coating thickness that could affect diameter tolerance.

Key Features

• Wire gauge size 51 with 0.0670-inch decimal diameter for precise small-hole applications
• 118-degree standard point angle with web-thinned, tapered-web geometry for reduced entry thrust
• High-speed steel construction rated for general-purpose drilling in metals and plastics
• Fast spiral flute design promotes chip clearing in short-depth holes
• Bright finish preserves tight diameter tolerance of -0.0005 to 0.0000 inches
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks and collets accepting a 0.0670-inch straight-cylindrical shank, across handheld, bench, and machine drilling setups.

Installation Notes

Secure the shank fully in a drill chuck or collet before operation and verify the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain tolerance. Inspect the cutting edges for wear before use, as small-diameter HSS bits are susceptible to breakage if run at excessive feed rates or used with lateral loading. Follow applicable shop safety practices for rotating tooling.
