Dewalt DWA1412 Tap Drill Set 5/16-18 F Drill 2 Piece

Product Description

The DEWALT DWA1412 is a 2-piece tap drill set designed for standard hand tapping operations using a 5/16-18 thread size. The set pairs a carbon steel taper chamfer tap with a letter F high speed steel drill bit, giving the installer both cutting tools needed to prep and thread a hole in a single kit. The tap features a bright finish and taper chamfer entry, which eases thread-starting in ferrous and non-ferrous materials. The 135-degree drill point angle on the F drill reduces walking and produces a cleaner entry hole. This kit is well suited for maintenance technicians, HVAC installers, plumbers, and electricians who need to tap threaded holes in equipment housings, brackets, and mounting hardware in the field or shop.

The DWA1412 is used wherever a 5/16-18 threaded hole must be created or restored. Typical applications include tapping new holes in sheet metal, steel plate, aluminum enclosures, and structural brackets during equipment installation or repair. The combination of the matching tap and drill in one package reduces the risk of selecting a mismatched drill size. This set is appropriate for both light commercial and residential trade work where hand tapping is the required method.

Installation Notes

A licensed or qualified technician should secure the workpiece firmly before drilling and tapping to prevent movement. Use cutting oil or thread-cutting fluid when tapping steel to extend tool life and improve thread quality. Advance the tap gradually and back off periodically to clear chips and prevent tap breakage. Follow applicable safety standards for rotating tool use when operating the drill in a power driver or drill press.
