It features a negative rake angle of -5 degrees and a 75-degree lead angle, making it suited for heavy-duty interrupted and continuous cuts where insert stability and edge strength are priorities. The 1 inch by 1 inch square shank provides rigid clamping in standard toolpost and turret setups. Insert retention uses a combination clamp-and-pin method, which secures CN..43.. series inserts firmly under high cutting loads. Coolant-through capability is not included on this holder.\u003c\/p\u003e\u003cp\u003eThis toolholder is built for turning applications in production and job-shop environments, including OD turning of ferrous and non-ferrous materials on turret lathes, engine lathes, and machining centers with live tooling. It accepts CN..43.. inserts, with the compatible insert size code CNMG431-GN confirmed for this holder. The right-hand cutting direction suits standard spindle rotation for the majority of lathe setups. Overall holder length is 6 inches, and the head length is 1.25 inches, fitting most standard 1 inch shank toolpost positions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMCRN toolholder style with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eNegative rake angle of -5 degrees for improved insert edge strength\u003c\/li\u003e\n\u003cli\u003e1 inch by 1 inch shank cross-section, 6 inches overall length\u003c\/li\u003e\n\u003cli\u003eClamp-and-pin insert holding method for secure seating under load\u003c\/li\u003e\n\u003cli\u003eAccepts CN..43.. series inserts including CNMG431-GN\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept CN..43.. series inserts, with confirmed compatibility with the CNMG431-GN insert size code.

Ensure the machine spindle is fully stopped and the machine is in an energy-isolated state before changing inserts or mounting the toolholder. Secure the shank in a 1 inch toolpost, turret block, or boring bar holder to the toolpost manufacturer torque specification. Inspect insert seat and clamping pin for wear before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MCRN\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\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: 1.25 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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 3606515\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51731992412466,"sku":"3606515","price":179.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1bfbf4d4f4a1f383f9f20658da9f8dc0.jpg?v=1788737760","url":"https:\/\/voomisupply.com\/products\/iscar-3606515-turning-toolholder-right-hand-mcrn","provider":"Voomi Supply","version":"1.0","type":"link"}
