Dewalt Accessories DWA1420 Drill Tap Set 6mm-1.00

Product Description

The DEWALT ACCESSORIES DWA1420 is a two-piece drill and tap set designed for creating and repairing internal threads in metal. The set includes a 6mm-1.00 tap and a No. 9 drill bit, both constructed from high-carbon steel for long service life on demanding jobs. The tap features a patented core diameter that reduces breakage under load. The drill bit uses a black oxide split point tip, which improves wear resistance and starts on contact without walking. This set is suited for licensed tradespeople and experienced mechanics who need precise metric threading in a compact, job-ready format.

This set is intended for metalworking applications where internal metric threads must be cut or restored. The 6mm-1.00 thread specification is a standard metric coarse pitch used across a wide range of fastener applications in HVAC equipment, plumbing fixtures, electrical enclosures, and general mechanical assemblies. The No. 9 drill bit prepares the correct tap drill hole for the 6mm-1.00 thread, eliminating the need to cross-reference a separate tap drill chart on the job site. Each set contains two pieces and ships as a single unit of measure.

Key Features

• High-carbon steel construction for durability in tough metalworking applications
• Patented tap core diameter reduces breakage during threading
• Black oxide split point drill bit improves wear resistance and self-starts without walking
• 6mm-1.00 tap paired with the correct No. 9 tap drill bit in one package
• Creates and repairs internal metric threads in metal

Compatibility

Designed for use in metal threading applications requiring a 6mm-1.00 metric coarse thread specification. Compatible with standard tap wrenches and drill drivers suited for No. 9 drill bits.

Installation Notes

A licensed machinist, millwright, or experienced trade technician should perform precision threading work on critical mechanical assemblies. Secure the workpiece before drilling and apply cutting fluid when tapping metal to reduce heat and extend tool life. Follow standard hand-tapping technique, backing off the tap periodically to clear chips and prevent binding. Never force the tap against resistance, as high-carbon steel tools can fracture under excessive torque.
