Chicago-latrobe 49911 Drill Bit Set 13 Pc Hss Jobber

Product Description

The CHICAGO-LATROBE 49911 is a 13-piece jobber length drill bit set designed for general-purpose metalworking and multipurpose drilling applications. The set is manufactured from high speed steel (HSS) with a bright, uncoated finish, and features a standard 118-degree split point angle for accurate starts on common metals and materials. All bits use a straight shank for compatibility with standard drill chucks. Coverage runs from 1/16 inch through 1/4 inch in 1/64-inch step increments. Right-hand cutting direction is standard across all 13 sizes. The bits are stored in a metal or plastic index case for organized jobsite access. This set is a staple for HVAC, plumbing, and electrical trades requiring consistent through-hole drilling in sheet metal, strut, and light structural material.

The 49911 set is suited to residential and light commercial service work where a compact, inch-sized range of drill bits is needed on a daily basis. The 1/64-inch step increments allow tradespeople to drill precisely sized holes for wire runs, pipe hangers, duct flanges, and equipment mounting brackets. The jobber length profile provides a practical reach-to-rigidity balance for hand drills and drill presses alike. Licensed contractors and service technicians who carry a general-purpose drill set will find the 13-piece range covers the most frequently called-upon sizes in field work.
