Built from steel, it features a 1 inch by 1 inch square shank and an overall length of 6 inches. The toolholder uses a clamp-and-screw insert holding method, providing secure, repeatable seating for VN..43-series inserts with a 0.5 inch inscribed circle. It carries a 3-degree lead angle and is suited for general-purpose external turning where left-hand tool approaches are required. This is a professional-grade toolholder installed and maintained by machinists and CNC lathe operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe HERTEL 1000197 is intended for external turning applications on ferrous and non-ferrous workpieces where a left-hand cutting direction is specified. The MVJN style and negative rake geometry are well matched to interrupted cuts, hard materials, and high-feed roughing passes. The 2 inch head length and 1.25 inch back-of-bar to cutting edge dimension allow proper tool positioning in standard MVJN-compatible toolpost or turret stations. This toolholder is cataloged under the Multi-Option series and ships as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand MVJN toolholder style with negative rake geometry\u003c\/li\u003e\n\u003cli\u003e1 inch by 1 inch steel shank, 6 inches overall length\u003c\/li\u003e\n\u003cli\u003eClamp and screw insert holding method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eAccepts VN..43-series inserts with 0.5 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003e3-degree lead angle for positive chip control during external turning\u003c\/li\u003e\n\u003cli\u003eHead length of 2 inches with 1.25 inch back-of-bar to cutting edge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with VN..43-series negative rake turning inserts, specifically VN.. 432 geometry inserts with a 0.5 inch inscribed circle.

Secure the shank fully in the toolpost or turret pocket and confirm proper tool height alignment before resuming operation. Follow the machine manufacturer and insert manufacturer torque guidelines when tightening the clamp screw on the insert. Inspect the insert seat and clamp surfaces for chips or debris before each insert change to maintain accurate cutting edge positioning.\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: 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: 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 (VN.. 432)\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1000197\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51751213891890,"sku":"1000197","price":341.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88d9fd6a02a23681516206930fdf11ed.jpg?v=1788922282","url":"https:\/\/voomisupply.com\/products\/hertel-1000197-lh-mvjn-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
