Cleveland C71130 Jobber Drill Bit Wire 30 0.1285 in Hss

Product Description

The CLEVELAND C71130 is a jobber-length drill bit in wire gauge size 30, with a decimal diameter of 0.1285 inches. Built from high speed steel with an oxide coating, it is designed for general-purpose drilling in metal, wood, and plastic across a range of production and maintenance applications. The 118-degree standard point angle and two-flute regular spiral geometry produce clean entry and efficient chip evacuation. Web-thinning reduces thrust load at startup. Licensed tradespeople and machinists reach for this bit when they need a reliable, consistent wire-gauge drill for everyday hole-making tasks in shop or field settings.

The C71130 suits residential and commercial applications wherever a wire size 30 hole is required. Common scenarios include drilling pilot holes for fasteners, electrical conduit work, plumbing rough-in, and light fabrication. The straight-cylindrical shank fits standard three-jaw keyless and keyed chucks on handheld drills and drill presses alike. It is sold individually but ordered in multiples of 12, making it practical to stock as a consumable for high-turnover jobsites or shop bins.

Compatibility

Designed as a general-purpose jobber-length replacement bit in wire gauge size 30; compatible with any standard three-jaw chuck accepting a 0.1285-inch straight-cylindrical shank on handheld drills, drill presses, and CNC equipment.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Power down and lock out the drill press or tool before changing bits. Use appropriate cutting fluid when drilling hardened or stainless materials to extend bit life. Discard bits showing visible chipping, burning, or diameter wear outside the stated tolerance.
