Built with a 1 inch x 1 inch square steel shank and an overall length of 5 inches, it accepts VN..33. series inserts held in place by a clamp and screw insert-holding method. The negative rake geometry is suited for heavier interrupted cuts and harder workpiece materials where edge strength is critical. The 3-degree lead angle and 1.66-inch head length position the insert precisely for controlled chip flow and consistent depth of cut. This toolholder is used by machinists and CNC operators working in production turning environments.\u003c\/p\u003e\u003cp\u003eThis toolholder fits standard square-shank tool blocks and turrets sized for 1 inch x 1 inch shanks. It is part of the Multi-Option series and is intended for use with VN..332 complete insert configurations. Typical applications include roughing and semi-finishing passes on steel, cast iron, and similar machinable materials in job shop and production machine shop settings. The back-of-bar to cutting edge dimension is 1.25 inches, which assists in tool offset setup and turret positioning.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMVJN toolholder style with negative rake for edge strength on demanding cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand orientation for standard OD turning applications\u003c\/li\u003e\n\u003cli\u003e1 inch x 1 inch square steel shank for rigid, low-deflection tool holding\u003c\/li\u003e\n\u003cli\u003eClamp and screw insert retention for secure insert indexing\u003c\/li\u003e\n\u003cli\u003eCompatible with VN..33. series inserts including VN..332\u003c\/li\u003e\n\u003cli\u003e5 inch overall length with 1.25 inch back-of-bar to cutting edge offset\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts VN..33. series inserts, with complete insert compatibility confirmed for VN..332.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the toolholder. Torque insert clamp screws to the insert manufacturer's recommendation using the appropriate Torx or hex key. Verify tool offset and cutting edge height at centerline before running the first part.\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: 5 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\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: VN..33.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Insert Compatibility\u003c\/strong\u003e: VN..332\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\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: Multi-Option\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.35 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: 1000194\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730597118258,"sku":"1000194","price":329.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60621ea4157f3f2532fa53265efc6638.jpg?v=1788720120","url":"https:\/\/voomisupply.com\/products\/hertel-1000194-mvjn-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
