Techniks 22245 ER25 Collet Chuck CAT40 Taper Shank

Product Description

The TECHNIKS 22245 is an ER25 collet chuck with a CAT40 taper shank, designed for use in CNC machining centers and milling applications. It accepts ER25 collets and provides a 4-inch projection from the spindle face, giving machinists clearance for deep-reach or fixture-heavy setups. The overall length is 6.68 inches. Collet capacity ranges from 3/32 inch minimum to 3/4 inch maximum, covering a wide range of cutting tool shank sizes. This chuck is installed by machinists and toolroom personnel setting up vertical or horizontal machining centers.

The TECHNIKS 22245 is suited for production and job-shop environments running CNC machining centers equipped with CAT40 spindles. The 4-inch projection makes it appropriate for workholding setups that require additional clearance between the spindle and the workpiece or fixture. It is commonly used with end mills, drills, reamers, and other round-shank cutting tools within the ER25 collet capacity range. Both production machinists and tool crib technicians will encounter this chuck in standard tooling inventories.
