Accupro 777849 DA300 Double Angle Collet Chuck 0.25 in

Product Description

The ACCUPRO 777849 is a double angle collet chuck designed for precision workholding in CNC machining and milling operations. Built on the DA300 collet system with a straight shank, it accepts collets ranging from 1/64 inch minimum to 1/4 inch maximum capacity. The 6.80 inch overall length and 1.31 inch projection provide the reach and rigidity needed for accurate tool positioning. Through-spindle coolant compatibility makes this chuck suitable for high-production environments where heat management is critical. Machinists and toolroom technicians install this chuck to secure small-diameter end mills, drills, and reamers in compatible spindles.

This collet chuck is suited for use in vertical and horizontal machining centers running the DA300 collet series. With a 1/2 inch shank diameter and 0.56 inch collet nut diameter, it fits standard DA300-compatible spindle bores. The straight shank design simplifies setup and alignment, making it appropriate for both production shops and job shops handling precision light-duty cutting operations with tooling up to 1/4 inch in diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before installing or removing the collet chuck. Ensure the shank bore and chuck surfaces are clean and free of chips or burrs before seating. Torque the collet nut using the appropriate DA300 spanner wrench to the machine or toolholder manufacturer guidelines.
