It features a 1 inch by 1 inch square steel shank and an overall length of 6 inches, providing rigid support for precision metal removal. The toolholder uses a negative rake geometry at a -10.5 degree primary rake angle, which improves insert edge strength and extends tool life in interrupted cuts and hard materials. It is compatible with VN..33. series inserts and conforms to ISO 13399 tooling data standards. Machinists and CNC technicians working in production turning environments are the primary installers.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for right-hand cutting direction turning applications in both production and job-shop environments. The MVJN style is commonly used for straight longitudinal turning and facing passes where a negative-rake insert provides the edge stability needed for consistent surface finish and dimensional control. The 1.69 inch head length and 1.25 inch back-of-bar to cutting edge dimension position the insert correctly for standard tool post and turret mounting configurations. No coolant-through feature is present, making it appropriate for flood or dry cutting setups where internal coolant delivery is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMVJN toolholder style with right-hand cutting direction and negative rake geometry\u003c\/li\u003e\n\u003cli\u003e1 inch by 1 inch square steel shank for rigid, stable clamping in standard tool posts and turrets\u003c\/li\u003e\n\u003cli\u003eCompatible with VN..33. series inserts, including VNMG331-F3M\u003c\/li\u003e\n\u003cli\u003e6 inch overall length with a 1.69 inch head length for consistent reach and clearance\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards for interoperability with CAM and tool management systems\u003c\/li\u003e\n\u003cli\u003ePart of the ISCAR Isoturn series, designed for reliable indexable turning performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with VN..33. series inserts, with confirmed compatibility with VNMG331-F3M insert geometry.

Power down and lock out the machine spindle before mounting or removing the toolholder from the turret or tool post. Ensure the shank seating surfaces are clean and free of chips or burrs before clamping to maintain proper cutting edge height. Torque clamp screws to the machine or turret manufacturer specifications only — do not use values not provided by the equipment manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MVJN\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: -10.5 degrees \/ -5.5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: VN..33.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: VNMG331-F3M\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: 1.69 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\u003eToolholder Material\u003c\/strong\u003e: Steel\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\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Turning\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: 3600665\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727296168242,"sku":"3600665","price":213.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/937c55e6a0ba2d81941b201078165472.jpg?v=1788676009","url":"https:\/\/voomisupply.com\/products\/iscar-3600665-mvjn-negative-rake-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
