Accupro QA-2 M18 Tapping Adapter M18 Tap Size 2 Adapter

Product Description

The ACCUPRO QA-2 M18 is a quick-change tapping adapter designed to connect M18 taps to compatible tapping chucks and holders in machine tool setups. Rated for a 14 mm tap shank diameter and an 11 mm tap square size, this adapter provides a secure, repeatable tap engagement in production tapping operations. It conforms to DIN 376 standards, ensuring dimensional consistency with tooling systems built to that specification. The adapter carries a 31 mm outside shank diameter, a 48 mm flange diameter, and an overall length of 46 mm. It is intended for use by machinists and toolroom technicians working on CNC machining centers, drill presses, and tapping machines.

This adapter is suited for metalworking environments where M18 threaded holes are tapped at volume. The quick-change feature allows fast tap swaps without removing the holder from the spindle, reducing cycle time in repetitive tapping applications. Typical installations include job shop and production floor settings handling medium-to-large threaded fastener applications in steel, cast iron, and similar materials. Coolant-through capability is not supported on this unit, so flood or mist coolant delivery at the tool perimeter is the standard approach. The Series WE 2 designation aligns this adapter with the WE 2 quick-change tapping system family.

Key Features

• Quick-change design allows fast tap exchanges without spindle removal
• DIN 376 compliant for dimensional interchangeability with compatible tooling systems
• 14 mm tap shank diameter and 11 mm tap square size sized for M18 taps
• 46 mm overall length with 11 mm projection and 30 mm tap depth
• 48 mm flange diameter and 31 mm outside shank diameter for stable chuck engagement
• Series WE 2 designation for system-level compatibility identification

Compatibility

Designed for use with M18 taps in the Series WE 2 quick-change tapping system. Conforms to DIN 376 standards. Specific chuck and holder compatibility should be verified against the WE 2 system specifications prior to installation.

Installation Notes

Installation and removal should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop lockout/tagout procedures. Verify that the tap shank diameter and square size match the adapter before seating the tap. Inspect the adapter seating surfaces for chips or wear before each use, as debris can affect tap concentricity and thread quality. Coolant-through is not available on this adapter, so ensure external coolant delivery is positioned appropriately for the application.
