Accupro 777842 DA180 Double Angle Collet Chuck 0.75 in

Product Description

The ACCUPRO 777842 is a double angle collet chuck designed for precision CNC milling and machining center applications. Built on the DA180 collet series, it accepts collets ranging from 3/64 inch minimum to 3/4 inch (0.75 inch) maximum capacity, making it suitable for a wide range of end mills, drills, and round-shank tooling. The chuck features a straight shank with a 1-1/4 inch shank diameter and an overall length of 5 inches. A through-spindle coolant design channels coolant directly to the cutting zone, supporting high-speed and high-precision operations. Weighing 1 pound, this chuck is intended for installation by machinists and toolroom technicians in production and job-shop environments.

This collet chuck is used in vertical and horizontal machining centers equipped with straight-shank spindle interfaces that accept the DA180 double angle collet system. It is suited for residential toolroom setups and commercial production floors alike. The 1.83 inch projection keeps tooling close to the spindle nose, reducing overhang and improving rigidity during cutting operations. The 1.44 inch collet nut diameter provides solid clamping force across the full collet capacity range.

Compatibility

Designed as an OEM-style toolholder for machining centers and milling machines configured with a straight-shank spindle interface that accepts DA180 series double angle collets.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before mounting or removing toolholders. Use a properly rated collet nut wrench to seat the collet nut to the manufacturer-specified engagement; do not use impact tools on collet nuts. Verify through-spindle coolant line integrity and confirm the chuck seats fully in the spindle before resuming operation.
