Part of the Isoturn series, it features a negative rake angle of -5 degrees and a 75-degree lead angle, providing stable cutting geometry for medium to heavy-duty turning. The toolholder accepts CN..43.. series inserts secured by a clamp and pin holding method, delivering reliable insert retention under aggressive cutting conditions. The 1 inch by 1 inch square shank and 6 inch overall length make it a standard-fit option for a wide range of machine tool turrets.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for production turning environments where consistent insert indexing and repeatable tool positioning are required. It is designed for right-hand cutting direction, making it appropriate for standard OD turning passes on lathes equipped with turret or gang tooling setups. Machinists and CNC operators working in job shops, production facilities, or maintenance machining applications will find this a direct-fit replacement or new-setup toolholder. It does not support coolant-through delivery and is intended as a single-application turning tool rather than a multi-use holder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMCKN toolholder style with negative rake geometry for stable chip formation\u003c\/li\u003e\n  \u003cli\u003eAccepts CN..43.. inserts including compatible size CNMG431-GN\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e1 inch x 1 inch square shank for standard turret compatibility\u003c\/li\u003e\n  \u003cli\u003e75-degree lead angle reduces radial cutting forces\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept CN..43.. series inserts, with a compatible insert size code of CNMG431-GN.

Ensure the machine spindle is fully stopped and the turret is de-energized before mounting or removing the toolholder. Confirm shank seating depth and turret clamping force meet machine tool manufacturer specifications. Insert indexing should follow insert manufacturer guidelines for torque on the clamping screw.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MCKN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 75 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CN..43..\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: CNMG431-GN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3600271\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748700881202,"sku":"3600271","price":160.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a385541c0bfb94a4635c618d6d7ddbf0.jpg?v=1788896969","url":"https:\/\/voomisupply.com\/products\/iscar-3600271-turning-toolholder-right-hand-mckn","provider":"Voomi Supply","version":"1.0","type":"link"}
