Cleveland C72151 Jobber Drill Bit No. 51 Hss

Product Description

The CLEVELAND C72151 is a jobber-length drill bit ground from high speed steel and designed for general-purpose drilling in metal, wood, and plastics. It carries a wire gauge size of 51, equal to 0.0670 inches in decimal, with a standard 118-degree split-point geometry and a web-thinned, tapered web for reduced thrust at entry. The bright, uncoated finish keeps the tool ready for use as delivered. Two spiral flutes with a regular helix clear chips efficiently during through-hole and blind-hole operations. Overall length is 2 inches, with a 1-inch flute length and a straight-cylindrical shank of 0.0670 inches in diameter.

This drill bit is suited for light-duty production and maintenance drilling in trade and industrial environments. The jobber-length format makes it a standard choice for hand drills, drill presses, and CNC drilling operations where a compact, stiff geometry is preferred over extended-length reach. The Series 2002G designation places it in a well-established line of general-purpose HSS jobber drills. Machinists, fabricators, maintenance technicians, and trade professionals working with ferrous and non-ferrous materials will find this size covers a broad range of small-diameter hole requirements.

Key Features

Compatibility

Designed as a general-purpose OEM-style jobber drill bit compatible with any standard straight-shank drill chuck accepting a 0.0670-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Secure the shank fully in the chuck and verify runout before drilling. Always power down and lock out the machine before changing bits. Use appropriate cutting fluid or lubrication for ferrous materials to extend tool life and maintain hole-diameter tolerance within the stated range of -0.0005 to 0.0000 inches.
