Accupro T2640283 Spiral Point Tap 8-32 3 Flutes Plug

Product Description

The ACCUPRO T2640283 is a spiral point tap designed for cutting 8-32 unified coarse threads in through-hole applications. Manufactured from 3% vanadium high speed steel, this plug chamfer tap drives chips forward ahead of the cut, making it well suited for high-production tapping in steel and ferrous materials. It carries a 2B class of fit with an H3 thread limit, delivering consistent tolerance control across repeated cuts. The bright finish provides a clean, uncoated surface appropriate for use with cutting fluids. This tap is a standard hand or machine tap used by machinists, maintenance technicians, and tool-room professionals working in metal fabrication and industrial maintenance environments.

The T2640283 is intended for tapping through holes in steels and similar ferrous materials at the 8-32 thread size. Its plug chamfer — typically 3 to 5 threads of lead — makes it appropriate for starting in a drilled hole and running through to the opposite side. The H3 thread limit and 2B class of fit make this tap compatible with standard 8-32 fastener assemblies used in light structural, electrical enclosure, and general machine assembly work. It is sized for use in drill press, CNC, or hand-tapping operations where right-hand thread direction is required.

Key Features

• 8-32 thread size with right-hand thread direction and 2B class of fit
• 3% vanadium high speed steel construction for improved wear resistance over standard HSS
• Spiral point geometry drives chips forward, suited for through-hole tapping
• Plug chamfer provides a gradual lead-in for starting in drilled through holes
• H3 thread limit for consistent tolerance control in production tapping
• Bright finish compatible with a wide range of cutting oils and fluids

Compatibility

Designed for tapping 8-32 through holes in steels and ferrous materials. Suitable for hand-tapping and machine-tapping operations requiring a right-hand, 2B-class unified coarse thread.

Installation Notes

Always use a properly sized 8-32 tap drill before tapping to ensure correct thread engagement. Apply cutting oil or tapping fluid to extend tool life and improve thread finish, particularly in steel. Secure the workpiece and align the tap perpendicular to the drilled hole before starting. On machine setups, verify spindle speed is appropriate for the material and tap diameter before engaging the feed.
