It features a 2-inch pilot diameter and a 6-inch projection from flange to nose end, placing the cutter well clear of the spindle for deep-reach applications. The nose diameter measures 4.88 inches, and the holder is balanced to 30,000 RPM, making it suitable for high-speed machining environments. A 1-14 lock screw thread retains the shell mill. Weighing 20 pounds, this is a heavy-duty tooling component intended for professional machine shop use.\u003c\/p\u003e\n\u003cp\u003eThis holder is used in horizontal and vertical CNC machining centers equipped with CAT50 spindle interfaces. It accommodates shell mill cutting diameters ranging from 5-1\/2 to 6 inches, making it appropriate for wide-face milling passes on structural components, fixtures, and large workpieces. The 6-inch projection allows clearance for setups where standard-length holders would create interference. Through-coolant is not supported by this holder. It is a direct-mount tooling solution installed by CNC machinists and tooling setup technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT50 taper shank for compatibility with CAT50 spindle interfaces\u003c\/li\u003e\n  \u003cli\u003e2-inch pilot diameter with 4.88-inch nose diameter for large-diameter shell mills\u003c\/li\u003e\n  \u003cli\u003e6-inch flange-to-nose projection for extended-reach setups\u003c\/li\u003e\n  \u003cli\u003eBalanced to 30,000 RPM for high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches for precise runout control\u003c\/li\u003e\n  \u003cli\u003eLock screw thread size 1-14 using lock screw 20LS\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with shell mill cutting diameters in the 5-1\/2 to 6 inch range.

Ensure the machining center spindle is powered down and locked out before mounting or removing the holder. Clean the CAT50 taper interface on both the holder and the spindle to remove chips and debris before seating. Verify torque on the retention knob and lock screw per the machine tool manufacturer specifications before running.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 4.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection Flange to Nose End\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShell Mill Cutting Diameter Range\u003c\/strong\u003e: 5-1\/2 to 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To RPM\u003c\/strong\u003e: 30,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Thread Size\u003c\/strong\u003e: 1-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw\u003c\/strong\u003e: 20LS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 20 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARLEC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C50-20SM6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":51971409150258,"sku":"C50-20SM6","price":325.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80c84c9c4e10ac7fd0ed9bf2bfc35cec.jpg?v=1789957005","url":"https:\/\/voomisupply.com\/products\/parlec-c50-20sm6-shell-mill-holder-cat50-2-inch-pilot","provider":"Voomi Supply","version":"1.0","type":"link"}
