Dewalt DWA1414 Tap Drill Set 3/8-16 5/16 Inch 2 Piece

Product Description

The DEWALT DWA1414 is a 2-piece tap and drill set matched for 3/8-16 thread cutting applications. The set includes a standard hand tap in 3/8-16 and a 5/16 inch high speed steel drill bit sized to produce the correct pilot hole for that thread. The tap is carbon steel with a bright finish and a taper chamfer, which provides gradual thread engagement and helps guide the tap squarely into the workpiece. This combination set reduces setup time by pairing the correct drill and tap in one package, making it practical for both shop and field use by plumbers, HVAC technicians, electricians, and general tradespeople.

This set is suited for tapping standard 3/8-16 UNC threads in mild steel, aluminum, and similar materials. The taper chamfer tap is best used for through-hole applications where the tap can advance fully through the material. Typical uses include threading holes in bracket stock, conduit hangers, equipment frames, and mechanical assemblies where 3/8-16 fasteners are standard. The 135-degree drill point angle on the included bit improves centering on hard or slick surfaces.

Installation Notes

A licensed technician or qualified tradesperson should secure the workpiece fully before drilling and tapping. Use appropriate cutting fluid when tapping steel to reduce heat and extend tap life. Back the tap out periodically to clear chips and prevent binding. Follow applicable safety standards for rotating tool use and always wear eye protection.
