Chicago-latrobe 57727 Drill Bit Set 118 Piece Hss Metric

Product Description

The CHICAGO-LATROBE 57727 is a 118-piece jobber length drill bit set built from high speed steel with an oxide finish. Designed for general-purpose metalworking and multipurpose drilling applications, this set covers metric sizing from 1 mm through 13 mm in straight-shank configuration. The 118-degree standard point angle suits a wide range of ferrous and non-ferrous materials. Bits are stored in a metal case that keeps the set organized and protected on the job. The right-hand cutting direction is standard for conventional drilling setups. This set is targeted at machinists, maintenance technicians, fabricators, and trade professionals who require a complete metric drill index in a single package.

This set is suited for metalworking environments including fabrication shops, maintenance facilities, and trade service work. The jobber length profile provides the balance of reach and rigidity preferred for general-purpose through-hole drilling in steel, aluminum, and similar materials. The DIN 338 specification confirms dimensional compliance with the widely recognized European standard for jobber drills, making these bits compatible with standard drill chucks and CNC toolholders accepting straight-shank tooling in the metric size range covered. The metal storage case supports organized tool accountability in professional shop environments.

Installation Notes

Installation and use of this drill bit set should be performed by qualified machinists or trade professionals familiar with drilling operations.
