Cleveland C72010 Jobber Length Drill Bit 5/32 in Hss

Product Description

The CLEVELAND C72010 is a jobber-length twist drill bit designed for general-purpose hole-making in metal, wood, and plastic. It measures 5/32 inches (0.1562 inches decimal) in diameter with a 3-1/8 inch overall length and a 2-inch flute length. The bit is manufactured from high speed steel (HSS) with a bright, uncoated finish. It features a standard 118-degree split point geometry with web thinning applied to reduce thrust and improve centering on entry. Two spiral flutes with a regular helix evacuate chips efficiently during through-hole and blind-hole drilling operations. Straight-cylindrical shank diameter is 0.1563 inches, compatible with standard three-jaw drill chucks.

This bit is suited for production and maintenance drilling in fabrication shops, HVAC installations, plumbing rough-in, electrical panel work, and general mechanical applications. The 4xD flute-to-diameter ratio and tapered web configuration make it appropriate for drilling mild steel, aluminum, copper, brass, and thermoplastics. It is sold individually but carries a minimum order quantity of 12 units, making it practical for shop stock replenishment or tool-crib inventory.

Key Features

• High speed steel construction for general-purpose drilling in metal, wood, and plastic
• 118-degree standard point angle with web thinning for reduced entry thrust and improved self-centering
• Two spiral flutes, regular helix, for efficient chip evacuation
• Bright uncoated finish — no coating buildup to affect dimensional tolerance
• Diameter tolerance of -0.0007 to 0.0000 inches per ASME B94.11M and DIN 338
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit conforming to ASME B94.11M and DIN 338 standards, compatible with any drill press, hand drill, or right-angle drill equipped with a standard three-jaw chuck sized for a 0.1563-inch straight shank.

Installation Notes

Secure the shank firmly in a calibrated three-jaw chuck before drilling. Always wear appropriate eye protection and secure the workpiece to prevent rotation. For metal drilling, apply cutting fluid to extend tool life and maintain dimensional tolerance. Inspect the cutting edges and web-thinned point before each use; a damaged or dull point increases thrust, affects hole quality, and risks workpiece damage.
