Built from steel, it features a 1 x 1 inch square shank and an overall length of 6 inches. The toolholder uses a clamp-and-screw insert holding method to secure VN..43-series inserts with a 0.5-inch inscribed circle. Negative rake geometry suits heavy interrupted cuts and harder workpiece materials. Licensed machinists and CNC setup technicians are the primary installers of this toolholder in production and job-shop turning applications.\u003c\/p\u003e\u003cp\u003eThis toolholder fits standard OD turning applications on lathes with a tool post or turret that accepts a 1 x 1 inch shank. The 3-degree lead angle and MVJN pocket geometry position the insert for general-purpose external turning. It is suited for both roughing and finishing passes when paired with the correct VN..43-series insert grade and geometry. The back-of-bar to cutting edge dimension is 1.25 inches, allowing predictable centerline setup. No coolant-through capability is provided, so external coolant delivery must be used when flood or mist cooling is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMVJN toolholder style with negative rake geometry for heavy-duty turning\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction\u003c\/li\u003e\n\u003cli\u003e1 x 1 inch square steel shank for rigid setup\u003c\/li\u003e\n\u003cli\u003eClamp-and-screw insert holding method for secure, repeatable insert seating\u003c\/li\u003e\n\u003cli\u003eAccepts VN..43-series inserts with 0.5-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003e6-inch overall length with 2-inch head length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with VN..43-series indexable inserts (complete insert compatibility: VN.. 432) with a 0.5-inch inscribed circle.

Before mounting or changing inserts, ensure the lathe is powered down, the spindle is locked, and all moving parts have come to a complete stop. Seat the shank fully in the tool post or turret and torque the clamping screws per the machine tool manufacturer's specifications. Handle indexable inserts with care — edges are sharp and can cause injury during handling and installation.\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\u003eRake\u003c\/strong\u003e: Negative\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: 2 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 Inscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: VN..43.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\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\u003eSeries\u003c\/strong\u003e: Multi-Option\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1000199\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752614035762,"sku":"1000199","price":329.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2dbb9ae5efb633338ef33a499a470f5f.jpg?v=1788929376","url":"https:\/\/voomisupply.com\/products\/hertel-1000199-mvjn-negative-rake-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
