It features a 1.5-inch pilot diameter and a 10-inch overall length, with a 6-inch projection from flange to nose end. Through-spindle and DIN flange coolant delivery are both supported, making it suitable for demanding milling operations where chip evacuation and tool cooling are essential. A TIR of 0.0002 inches ensures precise tool positioning. Licensed machinists and CNC setup technicians install and maintain this toolholder in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis shell mill holder is suited for horizontal and vertical machining centers using the CAT50 taper standard. It accepts shell mills in the 4-inch to 5-inch cutting diameter range, covering a broad set of face milling and shoulder milling applications. The dual contact taper shank engages both the taper and the spindle face for increased rigidity compared to standard single-contact CAT toolholders, making it a preferred choice in high-speed or heavy-duty milling setups. Balanced to 10,000 RPM, it is appropriate for modern high-speed spindle applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT50 dual contact taper shank for enhanced spindle rigidity and reduced vibration\u003c\/li\u003e\n\u003cli\u003e1.5-inch pilot diameter accommodates shell mills in the 4-inch to 5-inch cutting diameter range\u003c\/li\u003e\n\u003cli\u003eThrough-spindle and DIN flange coolant delivery for effective chip control and tool cooling\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0002 inches for precise tool runout and repeatable positioning\u003c\/li\u003e\n\u003cli\u003eBalanced to 10,000 RPM for compatibility with high-speed machining centers\u003c\/li\u003e\n\u003cli\u003eLock screw thread size of 3\/4-16 for secure shell mill retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CAT50 dual contact spindle configurations on CNC machining centers.
