Cleveland C71142 Jobber Drill Bit Wire 42 Hss Oxide

Product Description

The CLEVELAND C71142 is a wire gauge size 42 jobber length drill bit designed for general-purpose drilling in metal, wood, and plastic. Manufactured from high speed steel with an oxide coating, it delivers reliable wear resistance across a wide range of drilling tasks. The bit measures 2.25 inches in overall length with a 1.25-inch spiral flute, a 118-degree standard drill point angle, and a straight-cylindrical shank diameter of 0.0935 inches. Two right-hand spiral flutes with a web-thinned, tapered web configuration provide efficient chip evacuation and reduced thrust. Machinists, maintenance technicians, and general contractors install this bit in standard drill presses and hand drills for everyday production and repair work.

The C71142 is suited for light-duty drilling applications where a wire gauge size 42 hole is required. Its general-purpose grade and regular spiral type make it a common choice for through-hole work in thin-gauge steel, aluminum, and similar materials. The 4xD flute-to-diameter ratio supports effective chip removal in short, shallow-depth holes. Sold individually per package, with a minimum order quantity of 12 units, this bit is typically purchased in volume for shop stock or field service kits.

Installation Notes

Install and remove drill bits only after the drill press or hand drill is fully powered down and the chuck key is clear of the chuck. Secure the workpiece with a clamp or vise before drilling to prevent spinning. Use cutting fluid when drilling ferrous metals to extend bit life. Inspect the cutting edges and web before each use and replace any bit showing chipping or excessive wear.
