Accupro 777712 Milling Chuck Collet 0.625 in Id 0.75 in Od

Product Description

The ACCUPRO 777712 is a milling chuck collet designed to hold cutting tools securely in milling chuck toolholders. With an inside diameter of 0.625 inches and an outside diameter of 0.75 inches, this collet seats into compatible chuck bodies to grip end mills, drills, and other shanked tooling during machining operations. The overall length of 2.1 inches provides standard reach for typical milling setups. Weighing 0.1 pounds, it is a compact, precision-ground component. Machinists and tool-and-die professionals install and swap these collets as part of routine tool changes on vertical and horizontal milling machines.

This collet is suited for use in machine shop environments where milling chuck toolholding systems are in service. It is appropriate for both light finishing cuts and moderate material removal passes where secure tool retention and concentricity are required. The 0.625-inch bore accepts standard fractional shank tooling, making it a common size on production and job-shop floors. Installation is performed by machinists during tool setup and changeover procedures.

Installation Notes

Installation is performed by a qualified machinist. Power down and lock out the machine spindle before inserting or removing any collet. Inspect the collet bore and chuck body for chips or debris before seating; contamination will affect runout and tool retention. Do not over-torque the retention nut beyond the chuck manufacturer specification.
