Accupro T1640244 Spiral Point Tap 6-32 Plug Vanadium Hss

Product Description

The ACCUPRO T1640244 is a spiral point plug tap designed for threading 6-32 UNC holes in metal workpieces. Built from HSS-E vanadium high speed steel with an oxide finish, it resists heat and wear during tapping operations. The spiral point geometry pushes chips forward ahead of the cutting edge, making it well-suited for through-hole applications. With 3 flutes, a plug chamfer, and a right-hand thread direction, this tap produces clean, accurate threads in a single pass. Overall length is 2 inches, thread length is 0.511 inches, and shank diameter is 0.141 inches.

This tap is used in machining and fabrication environments where 6-32 UNC internal threads are required. It is appropriate for through-hole tapping in ferrous metals, aluminum, and similar materials on drill presses, CNC machining centers, or manual tapping machines. The plug chamfer style with a 4-thread lead makes it a common choice for production threading where hole entry is pre-drilled and thread engagement depth is consistent. Thread limit is H4, supporting standard tolerance fits for 6-32 fasteners.

Key Features

• Spiral point design pushes chips forward — suited for through-hole tapping
• HSS-E vanadium construction provides enhanced heat and wear resistance over standard HSS
• Oxide finish improves lubricity and corrosion resistance during cutting
• Plug chamfer with H4 thread limit for standard 6-32 UNC tolerance fits
• Right-hand thread direction, 3 flutes
• No coolant-through requirement — compatible with standard cutting fluid application

Compatibility

Designed as a replacement-style spiral point tap for 6-32 UNC through-hole applications in standard machine tool setups and tapping heads accepting a 0.141-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians using a drill press, tapping head, or CNC machine with appropriate tap holders. Ensure the pilot hole is drilled to the correct tap drill size for 6-32 UNC threads before use. Apply cutting fluid or tapping oil to prolong tap life and improve thread finish. Do not reverse-drive the tap without chip-clearing cycles in interrupted or deep-hole conditions.
