Dewalt Accessories DWA1412 Drill Tap Set 5/16-18 Nc

Product Description

The DEWALT ACCESSORIES DWA1412 is a 5/16-18 NC drill and tap set designed for creating and repairing internal threads in metal applications. Built from high-carbon steel, the set includes a black oxide split point drill bit and a tap engineered to a patented core diameter that reduces the risk of breakage during use. The black oxide coating adds wear resistance, extending service life on tough jobs. This 2-piece set is suited for professional tradespeople and experienced DIYers who need reliable, repeatable thread-cutting performance in ferrous and non-ferrous metals.

The DWA1412 is used in maintenance, repair, and fabrication scenarios where 5/16-18 NC internal threads are required. Typical applications include re-threading damaged fastener holes in metal fixtures, equipment frames, and structural components. The set is packaged as a unit of two pieces, covering both the drilling and tapping operations in a single purchase, which reduces setup time on the job.

Key Features

• High-carbon steel construction for durability in demanding thread-cutting tasks
• Patented core diameter design reduces breakage risk during tapping operations
• Black oxide split point drill bit provides improved wear resistance and starts on contact without walking
• Covers both drill and tap operations for 5/16-18 NC threading in one set

Compatibility

Designed as an OEM-style replacement and standard-use tap and drill set for 5/16-18 NC thread profiles in metal repair and fabrication applications.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or experienced tradespeople using a tap wrench or drill press. Always secure the workpiece before drilling and tapping to prevent movement. Power down any associated equipment and relieve pressure before threading into live systems. Use appropriate cutting fluid on the tap to reduce friction and extend tool life.
