It features a 1 inch by 1 inch square shank with an overall length of 5 inches and a head length of 1.66 inches. The toolholder uses a clamp and screw insert holding method and accepts VN..33. series inserts with a 3\/8 inch inscribed circle. Constructed from steel, it delivers the rigidity needed for interrupted cuts and heavy stock removal on production turning operations. Licensed machinists and CNC operators working in job shop or production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for external turning operations requiring a left-hand cutting direction with a 3-degree lead angle. The MVJN style positions the insert at a negative rake angle, which increases cutting edge strength and is well matched to cast iron, hardened steel, and other difficult-to-machine materials. It fits standard OD turning setups on lathes with tool posts or turrets that accommodate a 1 inch square shank. The back of bar to cutting edge dimension is 1.25 inches, which governs centerline offset during setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand MVJN toolholder style with 3-degree lead angle for external turning\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry increases insert edge strength for interrupted or heavy cuts\u003c\/li\u003e\n  \u003cli\u003eClamp and screw insert retention provides secure seating under high cutting forces\u003c\/li\u003e\n  \u003cli\u003eAccepts VN..332 inserts with 3\/8 inch (0.3750 inch) inscribed circle\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity and dimensional stability in production use\u003c\/li\u003e\n  \u003cli\u003e1 inch by 1 inch shank fits standard OD turning tool posts and turrets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept VN..332 series indexable inserts with a 3\/8 inch inscribed circle.

Power down and lock out the machine before mounting or changing the toolholder or insert. Confirm shank seating and torque the clamp screw to the insert manufacturer specification using calibrated tooling. Verify cutting edge centerline height against spindle centerline before taking a first cut, using the 1.25 inch back-of-bar-to-cutting-edge dimension as a reference during setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Left 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..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\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\u003eWeight\u003c\/strong\u003e: 1.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Multi-Option\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1000193\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51751128432946,"sku":"1000193","price":356.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/796255db038196674994ba3eb469edd1.jpg?v=1788921780","url":"https:\/\/voomisupply.com\/products\/hertel-1000193-lh-mvjn-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
