It uses a wedge clamping method to secure VNMG 332 inserts with a negative rake angle of -4 degrees, providing rigid, repeatable insert positioning under heavy cutting loads. The shank measures 3\/4 x 3\/4 inches (19.05 x 19.05 mm), and the overall length is 4.5 inches. The toolholder body is constructed from steel. Licensed machinists, CNC operators, and toolroom technicians specify this holder for precision turning setups where consistent tool geometry and secure insert retention are critical.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for facing applications on conventional and CNC turning equipment. The DVJNL style designates a left-hand cutting direction with a 93-degree lead angle, making it appropriate for straight turning and facing passes where workpiece approach and clearance constraints favor left-hand orientation. The wedge clamping system is a production-proven method used across high-volume turning cells as well as job shop environments. The 3\/4 x 3\/4 inch shank fits standard tool blocks and turrets sized for that shank cross-section. The multi-use designation indicates suitability across a range of workpiece materials when paired with the appropriate VNMG 332 insert grade.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDVJNL style left-hand toolholder for facing operations\u003c\/li\u003e\n  \u003cli\u003eWedge insert clamping method for rigid, repeatable VNMG 332 insert retention\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry at -4 degrees rake angle\u003c\/li\u003e\n  \u003cli\u003e3\/4 x 3\/4 inch (19.05 x 19.05 mm) shank for standard turret and tool block fitment\u003c\/li\u003e\n  \u003cli\u003e4.5 inch overall length with 1.83 inch head length\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production turning environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept VNMG 332 inserts with a 3\/8 inch inscribed circle.

Power down and lock out the machine spindle and turret before seating or removing the toolholder. Confirm the wedge clamp screw and insert seat are clean and free of chips before seating the VNMG 332 insert. Follow the machine tool manufacturer's torque recommendations for wedge clamp screws — do not exceed specified values to avoid insert or seat damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: DVJNL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: VNMG 332\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Wedge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -4 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Facing\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.83 inches (46.48 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 4.5 inches (114.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.375 inches\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: 0.81 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153308\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5732678\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51748488773938,"sku":"5732678","price":250.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb6e205ccaab37a14bce98ecab9dfa8d.jpg?v=1788894345","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5732678-dvjnl-turning-toolholder-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
