Dewalt DWA1416 Tap Drill Set 1/2-13 27/64 Inch 2 Pc

Product Description

The DEWALT DWA1416 is a 2-piece tap drill set matched for 1/2-13 thread cutting applications. The set pairs a 1/2-13 carbon steel standard hand tap with a 27/64 inch high speed steel drill bit, giving technicians and tradespeople everything needed to drill and tap a single thread size in one package. The tap features a taper chamfer for easier thread starting and a bright finish. The drill bit is ground to a 135-degree split point angle for reduced walking on metal surfaces. This combination is suited for through-hole and blind-hole threading in metal fabrication, mechanical maintenance, and field repair work.

This set is appropriate for use in residential and commercial maintenance environments, machine shops, and job sites where 1/2-13 UNC threaded holes are required. Common applications include HVAC equipment mounting, electrical enclosure hardware, plumbing fixture anchoring, and general mechanical assembly. The 27/64 inch drill diameter is the standard tap drill size for a 1/2-13 UNC thread, making this a convenient matched set for professionals who want to avoid sizing errors on the job.

Installation Notes

Installation of threaded holes should be performed by a qualified tradesperson familiar with metal drilling and hand tapping procedures. Secure the workpiece before drilling and use appropriate cutting fluid when tapping steel or cast iron to extend tap life and improve thread quality. Follow the drill manufacturer guidance for drill speed based on material type. Inspect the tap for wear or damage before each use to avoid tap breakage in blind holes.
