Accupro QA-0 M3 Tapping Adapter M3 Tap Size 0 Adapter

Product Description

The ACCUPRO QA-0 M3 is a quick-change tapping adapter designed to hold M3 taps securely in compatible quick-change tooling systems. It accepts taps with a 3.5 mm shank diameter and a 2.7 mm square drive, providing a positive engagement that reduces tap slippage during threading operations. With an overall length of 26.5 mm and a tap depth capacity of 15 mm, it suits precision tapping in tight workpiece geometries. Machinists and toolroom technicians install this adapter when setting up CNC machining centers, drill presses, or tapping stations requiring fast tap changes without loss of alignment. It conforms to DIN 371 standards.

This adapter fits production and job-shop environments where M3 threading is performed on metal or composite workpieces. The quick-change design reduces setup time on multi-tap jobs by allowing tap swaps without removing the outer holder from the spindle. Its Series WE 0 designation identifies it within the WE modular quick-change tapping system, making it compatible with WE 0 size holders. It is well suited to both low-volume prototype work and high-cycle production runs where consistent thread quality on small-diameter holes is required.

Key Features

• Quick-change interface allows fast tap swaps without disturbing the outer holder
• Accepts M3 taps with 3.5 mm shank diameter and 2.7 mm tap square size
• 15 mm tap depth capacity with 7 mm projection
• DIN 371 compliant for standardized tooling compatibility
• Flange diameter of 22 mm for stable seating in the holder
• Outside shank diameter of 13 mm for holder engagement

Compatibility

Designed for use with Series WE 0 quick-change tapping holders accepting a 13 mm outside shank diameter. Fits M3 tap size per DIN 371.

Installation Notes

Installation is performed by machining professionals setting up tapping stations or CNC machining centers. Ensure the spindle and any driven tooling are fully powered down before inserting or removing the adapter. Confirm the tap shank and square dimensions match the adapter specifications before seating the tap. Follow the machine tool manufacturer guidelines and applicable shop safety standards when configuring quick-change tooling systems.
