Accupro QCLK-3/1-1/2 Inchesss Tapping Chuck 1-1/2 in Straight Shank

Product Description

The ACCUPRO QCLK-3/1-1/2"SS is a tension and compression tapping chuck designed for precision tapping operations in machining environments. It features a 1-1/2 inch straight shank and accommodates a maximum tap capacity of 1-3/8 inches (M33 metric equivalent). The chuck uses a quick-change system with a Size 3 adapter and has a projection of 3.818 inches and a nose diameter of 3.07 inches. It is intended for use in CNC machining centers and production tapping applications where consistent thread quality and float compensation are required. Installation and operation are handled by skilled machinists and toolroom professionals.

This tapping chuck is suited for production and job-shop environments running both standard and pipe tapping operations. The minimum tap capacity is 13/16 inch, and the minimum pipe tap capacity is 1-3/8 inches, making it appropriate for a wide range of threading tasks on ferrous and non-ferrous materials. The quick-change interface allows for fast adapter swaps between operations, reducing downtime on the spindle. It is compatible with machining centers that accept a 1-1/2 inch straight shank toolholder.

Compatibility

Designed for use with machining centers and tapping machines that accept a 1-1/2 inch straight shank toolholder and Size 3 tapping adapters. Supports taps from 13/16 inch minimum up to 1-3/8 inch maximum capacity, including pipe taps up to 1-3/8 inch.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the chuck. Verify shank diameter compatibility and proper adapter size before securing the toolholder. Follow the machine tool manufacturer guidelines for drawbar torque and retention force when seating straight shank toolholders.
