It features a 1 x 1 inch square shank and an overall length of 6 inches, making it suitable for a wide range of turning center setups. The toolholder uses a clamp-and-pin (Multiple Lock) insert holding method and accepts VN..33.. style inserts with a 3\/8 inch inscribed circle. A negative rake angle of -12.8 degrees and a -3 degree lead angle are built into the geometry. The body is constructed from steel for rigidity under heavy cutting loads. Licensed machinists and CNC setup technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for right-hand turning operations across a broad range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous alloys, and superalloys — corresponding to material codes H, K, M, N, P, and S. The -3 degree lead angle suits general-purpose external turning where controlled chip direction and consistent insert engagement are required. It is well suited to production turning environments where repeatable tool offsets and quick insert indexing are priorities. The back-of-bar to cutting edge distance is 1.25 inches, which must be accounted for during tool offset entry.\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\u003eMultiple Lock insert retention system using clamp and pin for secure insert seating\u003c\/li\u003e\n\u003cli\u003eAccepts VN..33.. inserts (compatible insert size code VN33, 3\/8 inch inscribed circle)\u003c\/li\u003e\n\u003cli\u003e1 x 1 inch square steel shank with 6 inch overall length\u003c\/li\u003e\n\u003cli\u003eRake angle of -12.8 degrees; lead angle of -3 degrees\u003c\/li\u003e\n\u003cli\u003eUniversal primary workpiece material compatibility (H, K, M, N, P, S material codes)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts VN..33.. style indexable inserts with a compatible insert size code of VN33 and a 3\/8 inch inscribed circle.

Before mounting or indexing inserts, ensure the machine spindle is locked and all axes are at a safe position. Verify that the toolholder shank seats fully and squarely in the turret pocket or tool block before tightening. Follow the machine tool manufacturer torque specifications for the turret clamping hardware; do not rely on feel alone when securing the toolholder.\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\u003eInsert Compatibility\u003c\/strong\u003e: VN..33..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: VN33\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin (Multiple Lock Series)\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: -12.8 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -3 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: 1.66 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Catalog Number\u003c\/strong\u003e: MVJNR163D\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00071714\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558284886322,"sku":"00071714","price":227.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45993e99c97470adad8107c10824d836.jpg?v=1786408485","url":"https:\/\/voomisupply.com\/products\/seco-00071714-mvjn-negative-rake-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
