It accepts a 0.75 inch pilot diameter and features a 1.77 inch nose diameter, providing a rigid connection between the spindle and shell mill cutter. The holder supports through-spindle coolant delivery, directing coolant directly to the cutting zone for improved chip evacuation and tool life. It is balanced to 15,000 RPM, making it suitable for high-speed face milling and surfacing operations. Machinists and CNC setup technicians install this holder in production and job shop environments where repeatable tooling setups are required.\u003c\/p\u003e\u003cp\u003eThis shell mill holder is used in horizontal and vertical machining centers equipped with HSK63 spindle interfaces. Typical applications include face milling, shoulder milling, and high-feed milling operations on ferrous and non-ferrous materials. The through-spindle coolant capability makes it well-suited for operations where flood coolant alone is insufficient for heat management or chip control. The 0.669 inch projection from flange to nose end supports compact setups where spindle clearance is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHSK63 taper shank interface for high-rigidity, repeatable spindle connection\u003c\/li\u003e\n\u003cli\u003e0.75 inch pilot diameter accepts standard shell mill arbors\u003c\/li\u003e\n\u003cli\u003eThrough-spindle coolant delivery directs fluid to the cutting zone\u003c\/li\u003e\n\u003cli\u003eBalanced to 15,000 RPM for high-speed machining applications\u003c\/li\u003e\n\u003cli\u003e1.77 inch nose diameter accommodates larger-diameter shell mill bodies\u003c\/li\u003e\n\u003cli\u003eCompact 0.669 inch flange-to-nose projection for tight clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in machining centers with HSK63 spindle interfaces that support through-spindle coolant.

Use the appropriate HSK clamping tool and torque wrench as specified by the machine manufacturer — do not use improvised methods to seat or unseat the holder. Verify through-coolant passages are clear and that the machine coolant system is compatible before use. Inspect the HSK taper and holder bore for contamination or damage before each setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: HSK63 Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.77 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection Flange to Nose End\u003c\/strong\u003e: 0.669 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Through-Spindle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 15,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4502101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51736164827442,"sku":"4502101","price":328.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f1c372c8a178307aaf5f02431bff3cb.jpg?v=1788776280","url":"https:\/\/voomisupply.com\/products\/iscar-4502101-shell-mill-holder-hsk63-0-75-inch-pilot","provider":"Voomi Supply","version":"1.0","type":"link"}
