It accepts shell mills in the 4 to 5 inch cutting diameter range and features a 1.5 inch pilot diameter with a projection from flange to nose end of 2 inches. The holder delivers through-spindle and DIN flange coolant delivery, directing coolant directly to the cutting zone for improved chip evacuation and tool life. A total indicator runout (TIR) of 0.0002 inches supports tight tolerances in production milling operations. Installation is performed by qualified machinists or CNC setup technicians.\u003c\/p\u003e\n\u003cp\u003eThis shell mill holder is suited for use on CAT50-spindle vertical and horizontal machining centers in production and job shop environments. It is intended for face milling and shoulder milling applications where large-diameter shell mills are mounted and driven at the spindle interface. The lock screw thread size of 3\/4-16 is standard for this holder class. The dual coolant delivery options, through-spindle and DIN flange, provide flexibility depending on the machine tool configuration in use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT50 taper shank interface for positive spindle engagement and repeatable tool location\u003c\/li\u003e\n  \u003cli\u003ePilot diameter of 1.5 inches accommodates shell mills in the 4 to 5 inch cutting diameter range\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches supports precision milling with minimal runout\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle and DIN flange coolant delivery for versatile coolant routing\u003c\/li\u003e\n  \u003cli\u003e2 inch projection from flange to nose end for reach in standard milling setups\u003c\/li\u003e\n  \u003cli\u003eLock screw thread size 3\/4-16 for secure shell mill retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment shell mill holder for machining centers equipped with a CAT50 spindle interface, accepting shell mills with a 1.5 inch pilot bore in the 4 to 5 inch cutting diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC toolroom technician.
