Accupro QA-1 M3 Tapping Adapter M3 Tap We 1 Series

Product Description

The ACCUPRO QA-1 M3 is a quick-change tapping adapter designed to hold M3 taps in compatible quick-change tap holders during machine tapping operations. It accepts taps with a 3.5 mm shank diameter and a 2.7 mm tap square size, ensuring a secure, torque-transmitting fit. The adapter conforms to DIN 371 standards and belongs to the WE 1 series. With an overall length of 28.5 mm and a flange diameter of 30 mm, this adapter is sized for light-duty metric tapping work. Machinists, toolroom technicians, and CNC operators use this adapter when setting up tapping heads on drill presses, CNC machining centers, or tapping machines.

This adapter is suited for production and job-shop environments where M3 metric tapping is performed on ferrous and non-ferrous materials. The quick-change design allows rapid tap changes without removing the entire holder from the spindle, reducing setup time in repeat or high-volume tapping cycles. It is compatible with WE 1 series quick-change tapping systems and is appropriate for use on vertical machining centers, drill presses, and dedicated tapping machines where DIN 371 tooling is specified.

Key Features

• Quick-change design allows fast tap swaps without removing the holder from the spindle

Installation Notes

Installation is performed by qualified machinists or toolroom technicians during machine setup. Ensure the tapping machine or machining center spindle is powered down and locked out before changing adapters. Confirm tap shank diameter and square size match the adapter specifications before seating the tap. Follow the machine manufacturer guidelines for securing the quick-change holder and verify proper tap projection before beginning a tapping cycle.
