Accupro QA-1/K 3/8 Tapping Adapter 3/8 Inch Through Coolant

Product Description

The ACCUPRO QA-1/K 3/8 is a quick-change tapping adapter designed for use with 3/8 inch taps in machine tool tapping operations. It accepts a tap shank diameter of 0.381 inches and a tap square size of 0.286 inches, providing a secure, accurate drive connection. The adapter features through-coolant capability, allowing coolant delivery directly to the cutting zone to reduce heat and extend tap life. With a projection of 0.276 inches and a tap depth of 0.512 inches, it is engineered for compact, precise tap positioning. Machinists and toolroom professionals install this adapter in CNC machining centers and tapping machines where quick-change tooling systems are used.

This tapping adapter is suited for production and job-shop environments running 3/8 inch taps on vertical machining centers, drill-tap machines, or dedicated tapping heads. The quick-change design reduces setup time between tap changes, making it practical for high-mix or high-volume tapping operations. It is part of the WE 1 KP series, with an overall length of 25.50 mm and a flange diameter of 30.00 mm, fitting the standard WE 1 KP quick-change system interface.
