Accupro QA-2/K 3/8 Tapping Adapter 3/8 in Quick-change

Product Description

The ACCUPRO QA-2/K 3/8 is a quick-change tapping adapter designed for use with 3/8 inch taps in CNC machining and production tapping operations. It accepts a tap shank diameter of 0.381 inches and a tap square size of 0.286 inches, providing a secure, positive drive connection. The adapter features through-coolant capability, directing cutting fluid directly to the tap for improved chip evacuation and tool life. Belonging to the WE 2 KP series, this adapter is sized at Tap Adapter Size 2 and is intended for use by machinists and tooling setups requiring repeatable, fast tap changes without removing the holder from the spindle.

This tapping adapter is suited for use in vertical and horizontal machining centers where quick-change tooling systems are employed. It is appropriate for light-to-medium production tapping in ferrous and non-ferrous materials where coolant-through capability is needed to manage heat and chip load. The adapter carries a projection of 0.433 inches, a tap depth of 0.787 inches, and an overall length of 40.00 mm, making it compatible with standard WE 2 KP quick-change tooling setups in shop and production environments.

Installation Notes

Installation should be performed by a qualified machinist familiar with quick-change tooling systems. Ensure the machine spindle is powered down and the toolholder is fully seated and locked before initiating any tapping cycle. Verify that coolant-through connections are properly engaged and free of obstructions before use. Follow the machine tool manufacturer guidelines for torque and drawbar preload when mounting the holder assembly.
