It features a 1 inch pilot diameter and a 2.25 inch nose diameter, with a projection from flange to nose end of 4 inches. Balanced to 30,000 RPM, this holder suits high-speed spindle applications where runout control is critical. Total indicated runout (TIR) is rated at 0.0002 inches, supporting tight tolerances on finish milling passes. The lock screw thread is 1\/2-20, using the included 10LS lock screw. Installation is performed by qualified machinists or CNC tooling specialists.\u003c\/p\u003e\n\u003cp\u003eThis shell mill holder is suited for use on CAT50-spindle VMCs and HMCs running shell mills in the 2.25 inch to 2.75 inch cutting diameter range. Typical applications include face milling of large flat surfaces on ferrous and non-ferrous workpieces in production and job-shop environments. The CAT50 taper provides the rigidity required for heavier depth-of-cut operations common in roughing and semi-finishing cycles. No through-coolant capability is present, so coolant delivery must be handled externally or via flood coolant at the work zone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT50 taper shank for direct mount in CAT50-spindle machining centers\u003c\/li\u003e\n  \u003cli\u003e1 inch pilot diameter with 2.25 inch nose diameter for shell mill retention\u003c\/li\u003e\n  \u003cli\u003eBalanced to 30,000 RPM for high-speed spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches for consistent runout control during finish milling\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 lock screw thread with 10LS lock screw included\u003c\/li\u003e\n  \u003cli\u003eAccepts shell mills in the 2.25 inch to 2.75 inch cutting diameter range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style shell mill holder for CAT50 taper spindle machining centers accepting shell mills with a 1 inch pilot bore and cutting diameters from 2.25 inches to 2.75 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or removing the holder.
