Accupro QA-1/K 8 Tapping Adapter Size 8 Quick-change

Product Description

The ACCUPRO QA-1/K #8 is a quick-change tapping adapter designed to hold Number 8 taps in compatible toolholding systems. It features a tap shank diameter of 0.168 inches and a tap square size of 0.131 inches, providing a precise, rigid connection between the tap and the holder. Through-coolant capability directs cutting fluid directly to the cutting zone, helping control heat and extend tap life during production tapping operations. Machinists and CNC operators working in metalworking, job shop, and production environments install this adapter when setting up tapping cycles on machining centers or drill presses equipped with quick-change tooling.

This adapter suits applications where repeatable, fast tap changes are required on production runs. The WE 1 KP series designation identifies the toolholding standard this adapter is built to. Through-coolant support makes it a practical choice for tapping harder materials or deeper holes where heat buildup and chip evacuation are concerns. It is sold individually and is appropriate for shops running Number 8 tapping operations that demand consistent tap alignment and quick changeover between setups.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or removing the tapping adapter. Confirm the tap shank seats fully and the tap square engages the drive slot before starting the spindle. Follow the toolholder manufacturer instructions for torque and retention when securing the tap in the adapter.
