Hertel 02500106 Jobber Drill Bit Set 29 Pc Hss Oxide

Product Description

The HERTEL 02500106 is a 29-piece jobber length drill bit set designed for general-purpose metalworking and multipurpose drilling applications. Built from high-speed steel (HSS) with an oxide finish, these bits handle the daily demands of production shops, maintenance trades, and field service work. The set covers 1/16 inch through 1/2 inch in 1/64-inch step increments, giving techs a complete range in a single case. All 29 bits feature a straight shank and a 118-degree standard point angle, which is the industry-standard geometry for starting on flat metal surfaces without a center punch on most materials.

This set is suited for metalworking, general fabrication, HVAC rough-in, plumbing rough-in, and electrical rough-in tasks where drilling through steel, aluminum, or similar materials is routine. The 1/64-inch step increments make it practical for precision fits on conduit knockouts, pipe hangers, equipment mounting, and sheet metal work. The included metal or plastic storage case keeps bits organized and indexed on the job site or in a service van. Installation and use by licensed trade professionals in commercial and residential settings is the primary application.

Installation Notes

Secure the bit firmly in the chuck before operation and verify the chuck key is removed prior to starting the drill. Use cutting fluid or cutting oil when drilling ferrous metals to extend bit life and reduce heat buildup. Power down and disconnect the drill from its power source before changing bits. Follow applicable OSHA and workplace safety guidelines for rotating tool use.
