It uses a C6 modular connection shank, allowing fast, repeatable tooling changes on compatible interfaces. The chuck grips cutting tools through a 12 mm hole diameter and delivers a 142 mm projection from the spindle face, making it suited for deep-reach operations. Hydraulic clamping provides consistent, even gripping force around the tool shank, reducing runout and improving surface finish. The unit supports through-coolant delivery and is balanced for operation up to 20,000 RPM. Installation and tool changes are performed by qualified CNC machinists or tooling technicians.\u003c\/p\u003e\n\u003cp\u003eThis chuck is intended for use in high-speed machining environments where runout control and tool stability are critical. The 142 mm projection accommodates setups that require extended reach into deep cavities or past workpiece fixtures. Through-coolant capability directs cutting fluid directly to the tool tip, improving chip evacuation and extending tool life in demanding materials. The 36 mm clamping depth and 22 mm nose diameter are suited to standard tooling shanks within the 12 mm bore range. Typical applications include aerospace, die and mold, and precision part machining where consistent performance across high spindle speeds is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eC6 modular connection shank for fast, repeatable tooling changes\u003c\/li\u003e\n  \u003cli\u003e12 mm hole diameter with 36 mm clamping depth for secure tool grip\u003c\/li\u003e\n  \u003cli\u003e142 mm projection for extended-reach machining setups\u003c\/li\u003e\n  \u003cli\u003eBalanced to 20,000 RPM for high-speed spindle operation\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs fluid to the cutting zone\u003c\/li\u003e\n  \u003cli\u003e22 mm nose diameter with overall length of 180 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CNC machining centers equipped with a C6 modular tooling interface.
