The holder accepts a 3\/4 inch bore and provides a 3 inch projection, allowing clearance for a wide range of milling operations. It features through-spindle and DIN flange coolant compatibility, directing coolant directly to the cutting edge for improved chip evacuation and tool life. With a TIR of 0.0002 inches and a balance rating of 25,000 RPM, this holder is suited for high-speed, high-precision applications. Machinists and CNC setup technicians install this holder in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill holder is intended for use in CAT50-spindle CNC vertical and horizontal machining centers. The 3 inch projection suits applications where extended reach is needed, such as deep pocket milling or workholding clearance situations. The through-coolant design works with machines equipped with through-spindle coolant systems or DIN flange coolant delivery. It is appropriate for ferrous and non-ferrous milling operations where runout control and high-speed balance are critical requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT50 taper shank for compatibility with standard CAT50 spindle interfaces\u003c\/li\u003e\n\u003cli\u003e3\/4 inch bore diameter accommodates common end mill shank sizes\u003c\/li\u003e\n\u003cli\u003e3 inch projection provides extended reach for deep-pocket and clearance applications\u003c\/li\u003e\n\u003cli\u003eThrough-spindle and DIN flange coolant support for direct cutting-edge coolant delivery\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0002 inches for high-precision runout control\u003c\/li\u003e\n\u003cli\u003eBalanced to 25,000 RPM for high-speed machining applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers with a CAT50 spindle interface and through-spindle or DIN flange coolant capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before inserting or removing the tool holder. Use the appropriate CAT50 pull stud and a calibrated torque wrench when securing the drawbar.
