Accupro T2680376 Spiral Point Tap M8 X 1 Plug 3 Flute

Product Description

The ACCUPRO T2680376 is a spiral point plug tap designed for machine tapping through-holes in aluminum and similarly machinable materials. It is manufactured from 3% vanadium high speed steel, which provides increased wear resistance and edge retention compared to standard M2 HSS. The plug chamfer distributes cutting load across the leading threads for smooth entry in powered tapping operations. With a D6 thread limit, this tap produces threads with controlled oversize tolerance suitable for standard fastener fits. It is sized for M8 x 1.00 metric threads and is a right-hand cut tool intended for CNC machining centers, drill presses, and tapping arms.

This tap is suited for production and job-shop environments where M8 x 1.00 metric through-hole threads are required in aluminum workpieces. The plug chamfer style makes it the standard choice for most through-hole tapping applications where chip evacuation out the back of the hole is acceptable. Its 22 mm thread length accommodates typical workpiece thicknesses encountered in fixture, structural, and general machined-component work. Machinists and tool-and-die professionals are the primary users of this tool.

Key Features

• M8 x 1.00 right-hand thread form for standard metric fastener compatibility
• 3% vanadium high speed steel construction for improved wear resistance over standard HSS
• Plug chamfer with 3 flutes for smooth entry and controlled chip flow in through-hole tapping
• D6 thread limit for consistent controlled-oversize tolerance on finished threads
• Bright finish with no coating, suitable for use with cutting oil in aluminum applications
• Coolant-through design not required — compatible with flood or manual lubrication

Compatibility

Designed for tapping M8 x 1.00 right-hand metric through-holes, primarily in aluminum. Consult tool holder specifications to confirm shank diameter fitment before use.

Installation Notes

This tap is intended for use by machinists on powered tapping equipment, CNC machining centers, or tapping arms. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tap. Use an appropriate cutting fluid or tapping compound for the workpiece material to extend tool life and protect thread quality. Inspect the tap for chipping or wear regularly, as a damaged tap can seize in the workpiece.
