Hertel 79888327 Jobber Length Drill Bit Set 13 Pc Hss

Product Description

The HERTEL 79888327 is a 13-piece jobber length drill bit set made from high-speed steel (HSS) with a bright, uncoated finish. It covers fractional inch sizes from 1/16 inch through 1/4 inch in 1/64-inch step increments, giving technicians and tradespeople a compact range for general-purpose drilling. The straight shank design seats in standard three-jaw chucks, and the 118-degree standard point angle suits a wide variety of common materials. The set ships in a reusable metal or plastic case for organized storage on the job or in a service van.

This set is designed for metalworking and multipurpose drilling applications in residential, commercial, and light industrial settings. It is well suited for HVAC technicians, plumbers, electricians, and general tradespeople who need a reliable fractional drill assortment for sheet metal, structural steel, conduit work, and similar tasks. The 13-piece range handles the most frequently called-for fractional sizes without the bulk of a full-index set.

Compatibility

Designed as a general-purpose fractional drill bit set for use with standard corded or cordless drills and drill presses equipped with three-jaw chucks accepting straight-shank bits.

Installation Notes

Secure the straight shank firmly in the chuck before drilling and verify the bit is centered to prevent walking on smooth surfaces — a center punch mark is recommended when drilling metal. Match drill speed (RPM) to the material and bit diameter: smaller bits and harder materials generally require lower feed pressure. Inspect bits for wear or chipping before each use, and replace any bit that shows cracking or excessive dulling to avoid workpiece damage or injury.
