Accupro T2670283 Spiral Point Tap 8-32 2 Flutes Hss

Product Description

The ACCUPRO T2670283 is a spiral point tap designed for cutting 8-32 unified coarse threads in through-hole applications. Built from 3% Vanadium High Speed Steel, it delivers improved wear resistance over standard HSS taps, making it a reliable choice for production threading in aluminum and similar non-ferrous materials. The plug chamfer provides a gradual thread lead-in over several threads, distributing cutting forces and reducing the chance of tap breakage on entry. With a bright finish and right-hand thread direction, this tap is a straightforward fit for standard CNC and manual tapping operations.

This tap is suited for light- to medium-duty tapping in aluminum stock, sheet metal, and fabricated components where 8-32 threads are required. The spiral point design pushes chips forward ahead of the tap, making it effective in through-holes where chip evacuation is critical. It is commonly used by machinists, maintenance technicians, and fabricators working in job shops, HVAC equipment assembly, and general manufacturing environments.

Key Features

• Thread size 8-32 with right-hand thread direction and 2B class of fit
• 2 flutes with spiral point geometry for forward chip ejection in through-holes
• Plug chamfer with H3 thread limit for controlled tolerance threading
• 3% Vanadium HSS construction for enhanced wear resistance over standard M2 HSS
• Bright finish with no coating — suitable for use with cutting fluid in aluminum applications
• No coolant-through design; compatible with flood or brush-applied cutting fluid

Compatibility

Designed as an OEM-style replacement or direct-use tap for 8-32 through-hole threading operations in aluminum. Compatible model or system fitment is application-dependent; verify thread limit and class of fit requirements before installation.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with tapping speeds, feeds, and proper tap alignment. Ensure the workpiece is securely fixtured and the tap is properly aligned to the hole axis before beginning the cut. Apply appropriate cutting fluid for aluminum to reduce heat buildup and extend tap life. Remove the tap periodically to clear chips and inspect for wear when tapping multiple holes in a production run.
