Chicago-latrobe 69858 Reduced Shank Drill Bit Set 33 Pc

Product Description

The CHICAGO-LATROBE 69858 is a 33-piece reduced shank drill bit set engineered for metalworking and general-purpose drilling applications. Built from high-speed steel (HSS) with an oxide finish, this set covers a range from 1/2 inch to 1 inch in 1/64-inch step increments, giving technicians and tradespeople the coverage they need without switching sets. The 118-degree standard point angle is suited for a broad range of common metals. All bits feature a 1/2-inch reduced shank, allowing use in standard 1/2-inch chuck equipment even at the larger diameter sizes. Bits are jobber length with a flute length of 3-1/8 inches, and the set stores in an included metal block for organized access on the job.

This set is designed for metalworking professionals and skilled tradespeople who require consistent, repeatable hole quality across a wide size range. The reduced shank design makes it practical for use with standard drill presses, hand drills, and portable equipment where a full-shank large-diameter bit would require a dedicated large-bore chuck. Typical applications include drilling through steel plate, pipe, structural members, and multipurpose substrates in HVAC, plumbing, and electrical rough-in work.

Installation Notes

Installation should be performed by qualified tradespeople familiar with drilling equipment operation and shop safety practices. Ensure the drill press or hand drill is powered down and the chuck is fully secured before seating the reduced shank bit. Always wear appropriate eye protection and secure the workpiece before drilling. Cutting speed and feed rate should be selected based on the workpiece material and bit diameter per standard machining references.
