Cleveland C73400 Jobber Drill Bit 1/16 Inch Hss 118 Deg

Product Description

The CLEVELAND C73400 is a jobber-length twist drill bit designed for precision drilling in metal, aluminum, and similar materials. Built from high speed steel with a bright uncoated finish, it carries a 118-degree split point that reduces walking and lowers thrust at entry. The straight-cylindrical shank measures 1/16 inch in diameter, and the overall length is 1-7/8 inches with a 7/8-inch flute length. The tapered web with web thinning improves chip evacuation and keeps cutting forces manageable in production drilling environments. This is a heavy-duty grade bit suited for machinists, HVAC fabricators, and trade professionals who need a reliable small-diameter drill for sheet metal and light structural work.

The C73400 is rated for aluminum as its primary workpiece material and performs well in general-purpose drilling of non-ferrous metals and soft steels. The 2-flute spiral configuration with a regular spiral type provides controlled chip removal in through-hole and blind-hole applications. With a shank length of 1.0000 inch, the bit seats securely in standard drill chucks and collets. It is manufactured to NAS 907 Type A standards, making it appropriate for aerospace-adjacent and precision fabrication work where dimensional consistency is critical.

Compatibility

Designed as an OEM-style replacement or standard stock drill bit for use in hand drills, drill presses, and CNC drill stations requiring a 1/16-inch straight-shank jobber-length bit. Compatible with any chuck or collet accepting a 0.0625-inch diameter shank.

Installation Notes

This drill bit is installed and replaced by machinists, HVAC sheet metal fabricators, and general trade professionals. Secure the shank fully in the chuck before operation and verify chuck key is removed before starting the drill. Use appropriate cutting fluid or coolant when drilling harder metals to extend bit life, even though this bit does not support coolant-through delivery. Inspect the cutting edges before use and replace the bit if chipping or dulling is evident to avoid workpiece damage.
