Dewalt DW1342 21-piece Jobber Drill Bit Set Hss Tin

Product Description

The DEWALT DW1342 is a 21-piece jobber length drill bit set built from high-speed steel (HSS) with a titanium nitride (TiN) coating. The TiN surface treatment reduces friction and extends cutting life compared to uncoated HSS. Bit sizes run from 1/16 inch through 1/2 inch in standard fractional increments, covering the most common hole sizes encountered in trade and general mechanical work. Each bit features a 135-degree split-point tip for fast penetration and reduced walking on entry, with a straight shank for compatibility with standard three-jaw chucks. The set ships in an included case for organized storage and job-site transport.

This set is suited for drilling into mild steel, aluminum, wood, and plastics. It is commonly used by electricians roughing in conduit holes, plumbers drilling through framing and light structural members, and HVAC technicians mounting equipment or fabricating sheet metal brackets. The fractional inch sizing range makes it a practical all-around set for service vans and shop use. Right-hand cutting direction is standard for conventional drill press and handheld power drill operation.
