Cleveland C11650 Jobber Drill Bit Letter V Hss Split Point

Product Description

The CLEVELAND C11650 is a jobber length drill bit sized to Letter V (0.3770 inches) and built from heavy-duty high speed steel with a bright, uncoated finish. The 135-degree split point reduces walking and cuts through material without a center punch, making it well suited for production and maintenance drilling. A spiral, regular-helix flute with web thinning and a tapered web configuration promotes chip evacuation and reduces thrust. The straight-cylindrical shank measures 0.3770 inches in diameter and seats securely in standard drill chucks. Overall length is 5.0 inches with a flute length of 3.625 inches. This bit is sold individually and meets NAS 907 Type B standards.

The C11650 is designed for drilling aluminum as a primary workpiece material, though the heavy-duty HSS construction handles general-purpose metalworking applications in maintenance, fabrication, and machine shops. The right-hand cut and two-flute spiral geometry make this bit compatible with standard drill presses, hand drills, and CNC drilling operations. It fits comfortably in production environments where NAS-specification tooling is required and where consistent hole size tolerance of -0.0010 to 0.0000 inches is critical to downstream operations.

Compatibility

Designed as an NAS 907 Type B compliant jobber length drill bit in the CLEVELAND Series 2222, compatible with any standard drill chuck accepting a 0.3770-inch straight-cylindrical shank.

Installation Notes

Installation of this bit is performed by machinists, tool-and-die workers, and maintenance technicians using standard drill presses, hand drills, or CNC equipment. Secure the straight shank fully in the chuck before operation and verify chuck key removal before powering the spindle. Apply an appropriate cutting fluid when drilling aluminum or steel to extend tool life and maintain hole tolerance. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
