Accupro QA-1 M4 Tapping Adapter M4 Tap We 1 Series

Product Description

The ACCUPRO QA-1 M4 is a quick-change tapping adapter designed to hold M4 taps in compatible tapping heads and machine tool spindles. Sized for a 4.5 mm tap shank diameter and a 3.4 mm tap square, it provides positive drive engagement during tapping operations. The adapter meets DIN 371 standards and belongs to the WE 1 series. Overall length is 28.5 mm, with a 7 mm projection and a 30 mm flange diameter. It is suited for use in CNC machining centers, drill presses, and tapping machines where consistent thread quality and repeatable depth are required.

This adapter is used in light-duty tapping applications calling for M4 thread sizes. The quick-change design allows the operator to swap taps without removing the entire toolholder from the spindle, reducing cycle time in production environments. It is a common tooling component in metal fabrication shops, job shops, and maintenance machining operations where metric threading is performed on steel, aluminum, and similar workpiece materials.

Installation Notes

This adapter is installed by machinists or tooling technicians. Power down and lock out the machine spindle before changing or seating any tapping adapter. Verify that the tap shank diameter and square size match the adapter before securing the tap. Follow the machine tool manufacturer guidelines for torque and retention when assembling quick-change tooling components.
