Accupro QA-2 M8 Tapping Adapter M8 Tap Size 2 Adapter

Product Description

The ACCUPRO QA-2 M8 is a quick-change tapping adapter designed to hold M8 taps in compatible quick-change tapping chucks and holders. Built to DIN 371 standards, this adapter features an 8 mm tap shank diameter and a 6.2 mm tap square size, ensuring a secure, precise fit for M8 tap shanks. It is part of the WE 2 series and is used in CNC machining centers, drill presses, and tapping machines where rapid tap changes are required. Machinists and tooling technicians rely on this adapter to maintain consistent tap alignment and reduce changeover time on production runs.

This adapter suits metalworking applications in both job shop and production environments. It is commonly used in CNC tapping operations, manual tapping machines, and gang-drilling setups where standardized quick-change tooling is in use. The WE 2 series is a recognized quick-change standard, making this adapter a reliable component in modular tapping systems. Coolant-through capability is not available on this unit, so it is best suited for applications where flood or external coolant delivery is used.

Installation Notes

Installation and removal should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine power isolated. Ensure the tap shank and adapter bore are clean and free of chips before seating the tap. Verify that the mating quick-change chuck is rated for the WE 2 series before assembly. Follow machine tool manufacturer guidelines for maximum RPM and feed rate when tapping M8 threads.
