Irwin IR60508 Hss Jobber Drill Bit 1/8 Inch 118 Degree

Product Description

The IRWIN IR60508 is a high speed steel jobber length drill bit designed for general-purpose drilling in metal, wood, plastic, and composite materials. Built to jobber length proportions, this bit offers a balanced combination of reach and rigidity suitable for hand-held drills and drill presses alike. The 1/8 inch diameter and 118-degree standard point angle make it a go-to choice for pilot holes, through-holes, and precision starter bores. Licensed electricians, plumbers, HVAC technicians, and general contractors routinely keep this size on hand for common trade drilling tasks.

This bit is well suited for residential and light commercial service work where a reliable, compact drill bit is needed for conduit knockout prep, fixture mounting, panel work, and general fastener pilot drilling. The straight shank fits standard 3-jaw chucks across corded and cordless drill platforms. The jobber length format is the industry standard for general-purpose boring tasks in tight or open access conditions.

Installation Notes

This bit is installed by trade professionals using corded or cordless drills with a 3-jaw chuck. Secure the straight shank firmly in the chuck before operation and verify bit is centered before applying feed pressure. Wear appropriate eye protection per OSHA standards when drilling. For metal applications, use cutting fluid to extend bit life and reduce heat buildup.
