It features a negative rake geometry and accepts VN..33. series inserts secured by a clamp and screw holding method. The shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches, making it a standard square-shank toolholder suited to a wide range of lathe turret sizes. Licensed machinists and CNC operators install this toolholder in production and job-shop turning applications where insert indexability reduces downtime and maintains consistent cutting geometry.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is intended for left-hand turning passes where the tool cuts from left to right relative to the workpiece. The MVJN style with its 3-degree lead angle suits finishing and light roughing cuts on steel, cast iron, and similar materials. The 1-inch square shank fits standard ANSI tool blocks and turret stations commonly found on mid-size CNC lathes. The back of bar to cutting edge distance is 1.25 inches, and the head length is 1.66 inches, allowing predictable tool offset entry 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 and negative rake geometry\u003c\/li\u003e\n  \u003cli\u003eAccepts VN..33. series inserts (3\/8 inch inscribed circle) via clamp and screw retention\u003c\/li\u003e\n  \u003cli\u003e1 inch x 1 inch square shank fits standard ANSI lathe turret tool blocks\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides reach for typical OD turning setups\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity and resistance to cutting forces\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through capability — external coolant delivery required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept VN..33. series indexable inserts, specifically the VN.. 332 insert style.

Power down and lock out the lathe spindle before mounting or removing the toolholder from the turret. Torque the insert clamp screw according to the insert manufacturer specifications and inspect the insert seat for chips or debris before seating a new insert. Verify tool offset and edge height to centerline after installation before taking a cut.\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\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\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. \/ 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\u003eSeries\u003c\/strong\u003e: Multi-Option\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.6 pounds\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: 1000196\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728584212786,"sku":"1000196","price":332.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bb6c6673a189cc2dc80438d39c7cd5e.jpg?v=1788693635","url":"https:\/\/voomisupply.com\/products\/hertel-1000196-lh-mvjn-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
