Techniks 16312 ER16 Collet Chuck BT30 Taper Shank

Product Description

The TECHNIKS 16312 is an ER16 collet chuck designed for precision toolholding in CNC milling and machining centers. It accepts ER16 collets with a capacity range from 1/16 inch up to 0.406 inches, making it suitable for a wide variety of end mills, drills, and reamers within that range. The chuck features a BT30 taper shank for direct mounting in compatible spindles. With an overall length of 6.63 inches and a 120 mm projection, it provides the reach and rigidity needed for standard machining applications. Weighing 1.65 pounds, it is a compact, straightforward toolholder for production or job-shop environments.

This collet chuck is intended for use in CNC vertical and horizontal machining centers equipped with BT30 spindle interfaces. It is a common toolholder choice in light-duty to medium-duty milling operations where ER16 collet versatility is required. Machinists, CNC setup technicians, and toolroom professionals typically specify this chuck when a balanced, general-purpose ER collet solution is needed at the BT30 taper size.
