Accupro QCK-2 St Dia 1 Inches Rigid Tapping Chuck Straight Shank

Product Description

The ACCUPRO QCK-2 ST DIA 1" is a rigid tapping chuck designed for precision tapping operations on CNC machining centers and other power-driven tapping setups. It features a 1-inch straight shank and a quick-change interface that allows fast adapter swaps without removing the chuck body from the spindle. The nose diameter measures 1.9685 inches, and the projection is 2.51 inches. Through-coolant capability directs cutting fluid directly to the tap for improved chip evacuation and tool life during deep or interrupted threading operations. Machinists and CNC operators working in production environments will find this chuck suited for high-cycle tapping work.

This rigid tapping chuck is used in machine shop environments where rigid tapping cycles are programmed into CNC controls and spindle synchronization handles thread pitch. It accepts a Size 2 tap adapter and covers a tap capacity range from 5/16 inch minimum to 7/8 inch maximum, making it suitable for a wide range of common thread sizes in ferrous and non-ferrous materials. Typical applications include production drilling and tapping cells in industrial, automotive, and general manufacturing settings.

Key Features

• Rigid tapping style for use with synchronized CNC spindle tapping cycles
• Quick-change design allows rapid tap adapter swaps at the machine
• Through-coolant capable for improved chip evacuation and tap longevity
• Tap capacity range: 5/16 inch minimum to 7/8 inch maximum
• Size 2 tap adapter interface for broad tooling compatibility
• Straight shank with 1-inch shank diameter for direct spindle mounting

Compatibility

Designed for use with Size 2 tap adapters on CNC machining centers equipped with rigid tapping capability and a straight-shank spindle connection accepting a 1-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or removing the chuck. Ensure the shank bore and collet surfaces are clean and free of chips or debris before seating the chuck. Verify through-coolant connections are properly sealed and torqued per the machine tool manufacturer specifications before running coolant under pressure.
