Accupro T2640342B Spiral Point Tap 10-32 Plug 2B

Product Description

The ACCUPRO T2640342B is a spiral point tap designed for cutting right-hand internal threads in steel workpieces. Built from 3% vanadium high-speed steel with a bright, uncoated finish, this plug-chamfer tap drives chips forward ahead of the cut, making it well suited for through-hole threading operations. It carries a 2B class of fit for standard unified inch thread tolerances. The tap features a 10-32 thread size, three flutes, a 16 mm thread length, and an overall length of 2.375 inches. It weighs approximately 0.08 pounds. Licensed machinists, tool-and-die makers, and maintenance technicians reach for this style of tap when consistent thread quality and chip evacuation are priorities.

This tap is intended for threading through holes in steel at the 10-32 unified fine (UNF) thread specification. It is a standard choice in general machining, maintenance and repair operations (MRO), and production environments where 10-32 fastener holes are required. The plug chamfer with 3-5 thread lead makes it versatile enough for most through-hole applications in ferrous materials. No coolant-through capability is incorporated, so conventional flood coolant or cutting oil applied externally is standard practice.

Key Features

• Spiral point geometry drives chips forward, keeping the flutes clear during through-hole threading
• 3% vanadium high-speed steel construction provides wear resistance in steel applications
• Plug chamfer offers a 3-5 thread lead for easy entry and general-purpose use
• 2B class of fit delivers standard tolerance control for unified inch threads
• Bright, uncoated finish allows direct visual inspection of the tap surface
• Right-hand thread direction compatible with standard tapping equipment and tap handles

Compatibility

Designed as a standard replacement or production tap for through-hole 10-32 UNF threading operations in steel using conventional tapping machines, drill presses, or hand tap handles.

Installation Notes

This tap is installed and operated by machinists or skilled maintenance technicians using a tapping machine, drill press with tapping attachment, or a hand tap wrench. Always ensure the pilot hole is drilled to the correct tap drill diameter for a 10-32 thread before beginning the tapping operation. Apply an appropriate cutting oil or tapping fluid to the work area to reduce friction and extend tool life. Never force the tap if resistance increases significantly — back off to break the chip before continuing.
