Cleveland C73437 Jobber Drill Bit Wire 9 Hss 118deg

Product Description

The CLEVELAND C73437 is a jobber-length drill bit sized at wire gauge 9 (0.1960 inch decimal equivalent), manufactured from high-speed steel with a bright, uncoated finish. It features a 118-degree split point for reduced walking and faster penetration, a two-flute regular spiral configuration, and a web-thinned, tapered web design that lowers thrust requirements during drilling. The straight-cylindrical shank measures 0.1960 inch in diameter and is compatible with standard drill chucks. With an overall length of 3.625 inches and a flute length of 2.4375 inches, this is a heavy-duty, general-purpose bit built for production and maintenance work. It meets NAS 907 Type A standards.

This bit is suited for drilling aluminum and similar non-ferrous and softer ferrous materials in light manufacturing, fabrication, and maintenance applications. The right-hand cut and regular spiral flute geometry support efficient chip evacuation in through-hole and blind-hole drilling. It is appropriate for use in drill presses, CNC machining centers, and handheld power drills where a straight-shank, jobber-length bit is specified. The Series 2228 designation places it in a heavy-duty HSS line built for consistent dimensional accuracy and repeat performance across production runs.

Key Features

• Wire gauge 9 size, 0.1960 inch decimal diameter with a tight tolerance of -0.0007 to 0.0000 inch
• 118-degree split point reduces center walking and lowers required thrust force
• Web-thinned, tapered web construction improves cutting efficiency and chip flow
• High-speed steel construction with bright uncoated finish for use across a range of workpiece materials
• Right-hand, two-flute regular spiral design supports clean chip evacuation
• Meets NAS 907 Type A specification for dimensional and performance standards

Compatibility

Designed as a jobber-length replacement or production bit for applications specifying a wire gauge 9, 0.1960-inch straight-shank HSS drill bit meeting NAS 907 Type A standards. Primary listed workpiece material is aluminum.

Installation Notes

This bit is installed and replaced by machinists, tool-and-die workers, and maintenance technicians using standard drill chucks accepting a 0.1960-inch straight-cylindrical shank. Secure the shank fully in the chuck before operation and confirm the work piece is clamped or fixtured to prevent movement. Inspect the cutting edges and point for wear or chipping before each use and replace the bit when dimensional tolerance or surface finish begins to degrade. Coolant-through is not supported on this bit; use appropriate cutting fluid applied externally when drilling conditions require lubrication.
