Cleveland C03051 Jobber Length Drill Bit 0.2090 in

Product Description

The CLEVELAND C03051 is a jobber length drill bit in wire size 4, with a diameter of 0.2090 inches, manufactured from high speed steel with a bright uncoated finish. The bit features a 118-degree standard point angle, fast spiral fluting, and a web-thinned, tapered web construction that reduces cutting resistance at the tip. Two flutes channel chips efficiently during through-hole drilling. The straight-cylindrical shank measures 0.2090 inches in diameter and 1.25 inches in length, making it compatible with standard drill chucks. Licensed machinists, tool and die workers, maintenance technicians, and general fabricators routinely spec this type of bit for production and repair work.

This drill bit is suited for drilling aluminum and general-purpose materials in both shop and field environments. With a flute length of 2.5 inches and an overall length of 3.75 inches, it falls within the standard jobber length range and fits common benchtop drill presses, hand drills, and CNC drilling setups. Right-hand cutting direction is standard for conventional drill press and hand-drill operation. The Series 2012 designation places this bit within a defined product family from CLEVELAND. It is sold individually.

Compatibility

Designed as a general-purpose jobber length drill bit for use with standard straight-shank drill chucks on drill presses, hand drills, and CNC drilling equipment. Primary workpiece material is aluminum, though the bit is rated for general-purpose use.

Installation Notes

Secure the straight-cylindrical shank firmly in a properly sized drill chuck before operation. Ensure the drill press or handheld drill is powered off and unplugged before installing or changing bits. Use appropriate cutting fluid or lubrication when drilling aluminum to reduce heat buildup and extend bit life. Inspect the cutting edges and point before each use and replace bits showing signs of chipping or dulling.
