Cleveland C73438 Jobber Drill Bit Wire 10 Hss 118 Deg

Product Description

The CLEVELAND C73438 is a jobber-length drill bit sized at wire gauge number 10, with a decimal diameter of 0.1935 inches. Built from high-speed steel with a bright uncoated finish, it features a 118-degree split point and a tapered web for reduced walking and easier penetration on entry. The two-flute spiral design with regular helix promotes efficient chip evacuation. At 3-5/8 inches overall length with a 2-7/16-inch flute length, this is a standard jobber-length configuration well suited for general-purpose drilling in production and maintenance environments. It meets NAS 907 Type A standards and carries a heavy-duty grade designation.

This bit is primarily rated for aluminum but performs across a range of soft-to-medium materials in typical shop and field applications. The straight-cylindrical shank measures 0.1935 inches in diameter and 1.1875 inches in length, making it compatible with standard drill chucks. It is commonly used by machinists, maintenance technicians, HVAC installers, and pipefitters who need reliable, repeatable hole sizing in wire-gauge formats. The web-thinned geometry reduces thrust load, which is advantageous in hand-drill and light drill-press work.

Key Features

• Wire size 10 diameter: 0.1935 inches, tight tolerance of -0.0007 to 0.0000 inches
• 118-degree split point with web thinning reduces center pressure and walking
• High-speed steel construction for heat resistance in repeated drilling cycles
• Bright uncoated finish for easy visual inspection of wear and edge condition
• NAS 907 Type A compliant — meets aerospace and industrial dimensional standards
• Regular spiral flute promotes consistent chip clearing in aluminum and soft metals

Compatibility

Designed as an OEM-style replacement or direct-use jobber-length drill bit for applications requiring wire gauge number 10 (0.1935-inch) hole sizing. Listed primary workpiece material is aluminum per manufacturer specification. Fits any standard drill chuck accepting a 0.1935-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the bit is properly seated before operation. Use appropriate cutting fluid or lubricant when drilling aluminum to extend edge life. Always wear eye protection; secure the workpiece before drilling to prevent rotation.
