Accupro QA-2 M20 Tapping Adapter Size 2 Din 376

Product Description

The ACCUPRO QA-2 M20 is a quick-change tapping adapter designed for use with M20 taps in CNC machining centers, drill presses, and tapping machines. It accepts a 16 mm tap shank diameter and a 12 mm tap square, providing a secure, repeatable connection between the tap and the toolholder. The adapter delivers a projection of 0.4331 inches (11 mm) and a tap depth of 1.1811 inches (30 mm), making it well suited for threading operations that require consistent depth control. Machinists and tooling setup technicians install this adapter as part of a quick-change tooling system to reduce tap changeover time and maintain alignment.

This adapter is intended for use in production and job-shop environments where M20 metric tapping is performed on ferrous and non-ferrous materials. It fits into toolholding systems that conform to the DIN 376 standard and belongs to the Series WE 2 family of quick-change tapping adapters. Typical applications include tapping threaded holes in machined components, fixtures, and fabricated assemblies. Coolant-through capability is not supported on this adapter. It is sold individually and is appropriate for both manual and CNC-controlled tapping cycles.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and all motion is locked out before changing adapters. Verify that the tap shank and square dimensions match the adapter specifications before seating the tap. Consult the toolholder manufacturer guidelines for proper engagement and retention torque procedures specific to the toolholding system in use.
