Accupro T2670342B Spiral Point Tap 10-32 Plug 2B Vss

Product Description

The ACCUPRO T2670342B is a spiral point tap designed for threading 10-32 unified fine threads in metalworking applications. It features a plug chamfer geometry with 2 flutes and is manufactured from 3% Vanadium High Speed Steel (VSS), which provides improved wear resistance over standard HSS. The bright finish leaves the base material exposed, making it well suited for applications where coating buildup in the flutes is a concern. Overall length is 2.375 inches with a thread length of 16 millimeters. The right-hand cut and Class 2B thread tolerance make it a standard choice for general-purpose tapping in production and maintenance environments.

This tap is rated for use in aluminum and similar non-ferrous materials, where spiral point geometry helps push chips forward and clear the cutting zone efficiently. The plug chamfer distributes the cutting load across several leading threads, making it appropriate for through-hole applications. Machinists, toolroom technicians, and maintenance professionals typically use this tap in drill press, CNC tapping, or hand-tapping operations where 10-32 threaded holes are required.

Key Features

• 10-32 unified fine thread form, right-hand cut
• Plug chamfer distributes load across multiple threads for through-hole tapping
• 2-flute spiral point geometry pushes chips forward to clear the hole
• 3% Vanadium High Speed Steel construction for improved wear resistance over standard HSS
• Class 2B thread tolerance for standard-fit threaded assemblies
• Bright finish with no coating buildup in the flute gullets

Compatibility

Designed as a standard replacement or production tap for 10-32 through-hole threading operations, particularly in aluminum and similar soft metals where spiral point geometry is preferred.

Installation Notes

This tap should be installed in a tap holder or collet that provides axial alignment to prevent thread distortion or tap breakage. Always ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for a 10-32 thread before tapping. Apply appropriate cutting fluid for the workpiece material to extend tool life. When the tap is worn or the thread form degrades, replace the tap rather than continuing to cut, as a damaged tap can seize in the hole.
