Value Collection 00382291 Combination Drill Tap 1/8-27 Nptf

Product Description

The VALUE COLLECTION 00382291 is a combination drill tap designed to drill and tap a hole in a single operation, eliminating the need for separate tooling steps. Built to the 1/8-27 NPTF thread standard, this tool is suited for creating tapered pipe threads in metal workpieces. The 4-flute high-speed steel construction provides clean chip evacuation and consistent thread form. With a drill size of 0.339 inches (Letter R), a thread length of 0.75 inches, and an overall length of 2.875 inches, it fits standard drill press chucks and hand-held power tools used in pipe fitting and light fabrication work.

This combination drill tap is intended for use in metalworking applications where NPTF pipe threads are required in a single pass. Typical use cases include creating threaded ports in manifolds, fittings, brackets, and mechanical assemblies made from steel, aluminum, or similar machinable metals. It is well suited for plumbers, pipefitters, HVAC technicians, and maintenance machinists who need to add tapped pipe thread ports without running a separate drill bit and tap. The compact overall length of 2.875 inches allows use in confined areas where longer tooling would be impractical.

Key Features

• Drills and taps in a single pass, reducing setup time and tooling changes
• 1/8-27 NPTF thread form for pressure-tight tapered pipe thread connections
• High-speed steel construction for durability in ferrous and non-ferrous metals
• 4-flute design promotes chip evacuation and thread accuracy
• Letter R drill size (0.339 inches) matched to 1/8-27 NPTF thread requirements
• Compact 2.875-inch overall length suits restricted-access applications

Compatibility

Designed as an OEM-style replacement or standard shop tool for applications requiring 1/8-27 NPTF threaded ports in machinable metals.

Installation Notes

Installation should be performed by a qualified machinist, pipefitter, or HVAC technician familiar with threading operations. Secure the workpiece firmly before drilling and apply cutting fluid to extend tool life and improve thread quality. Use at recommended speeds for the material being tapped and avoid forcing the tool, which can cause breakage. Inspect the finished thread with an NPTF plug gauge when pressure-tight connections are required.
