It accepts VN..332 series inserts and features a neutral hand orientation, making it suitable for straight turning and facing passes where insert geometry does the cutting work. The shank measures 0.75 inches wide by 0.75 inches tall with an overall length of 4.5 inches. Machinists and toolroom professionals use this holder in CNC and manual turning centers where consistent insert seating and repeatable tool life are required.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is applied in general-purpose external turning operations on ferrous and non-ferrous materials. The neutral hand design works equally well on lathes configured for right-hand or left-hand feed direction. Typical applications include roughing and semi-finishing passes on bar stock, shafts, and cylindrical workpieces. It is part of the HERTEL Multi-Option series, which standardizes insert platforms across a range of holder styles to reduce insert inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMVVN toolholder style with neutral hand orientation for versatile feed direction\u003c\/li\u003e\n  \u003cli\u003eNegative rake design for increased insert edge strength and longer tool life in interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eAccepts VN..332 series inserts for broad insert availability\u003c\/li\u003e\n  \u003cli\u003e0.75 inch x 0.75 inch square shank fits standard lathe tool blocks and quick-change holders\u003c\/li\u003e\n  \u003cli\u003e4.5 inch overall length provides adequate reach for most external turning setups\u003c\/li\u003e\n  \u003cli\u003ePart of the Multi-Option series for consolidated insert platform management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept VN..332 series indexable inserts.

Secure the shank fully in the toolpost block and confirm insert seating before taking a cut. Torque the insert clamp screw according to the insert manufacturer specification and inspect the insert pocket and clamp for wear or debris before each insert change. Verify tool centerline height relative to workpiece centerline after any holder change.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MVVN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: VN..332\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches (114.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.315 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Multi-Option\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1002859\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727345549618,"sku":"1002859","price":329.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25184110c82700b9dda1970ad6fae224.jpg?v=1788676558","url":"https:\/\/voomisupply.com\/products\/hertel-1002859-mvvn-indexable-turning-toolholder-3-4-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
