Irwin 3018010 Jobber Length Drill Bit Set 18 Pc Hss Tin

Product Description

The IRWIN 3018010 is an 18-piece jobber length drill bit set designed for metalworking and multipurpose drilling applications. Each bit is machined from high-speed steel and coated with titanium nitride (TiN) for extended wear resistance and reduced friction at the cutting edge. The set covers sizes from 0.0625 inches (1/16 inch) up to 0.5 inches (1/2 inch) with a straight shank configuration and right-hand cutting direction. The Turbomax point geometry promotes faster penetration and more accurate starts without a center punch. This set is built for electricians, plumbers, HVAC techs, and general tradespeople who drill through metal, wood, and plastic regularly.

The 3018010 set is suited for residential and light commercial trade work where a broad range of bit sizes must be on hand. Typical applications include drilling pilot holes for conduit hangers, sheet metal penetrations, junction box knockouts, and pipe support brackets. The 18-piece size range handles the majority of common hole sizes encountered on a service call or rough-in job. Bits ship in a hard storage case that keeps the set organized on a work truck or in a tool bag.

Installation Notes

Drill bit sets of this type are installed and used by electricians, plumbers, HVAC technicians, and general contractors. Always ensure the drill is powered off and the chuck is fully tightened before beginning. Use appropriate cutting fluid when drilling through hard metals to preserve coating life and prevent bit overheating. Inspect each bit for chipping or deformation before use and replace any bit that shows visible damage.
