It features a 16mm x 16mm square shank and a 95-degree lead angle with negative rake geometry. The screw-clamp insert holding method provides rigid, repeatable seating for WNM-style inserts. Overall length is 100mm (3.94 inches) with a head length of 26mm (1.02 inches). Licensed machinists and CNC operators install this holder in production and job-shop turning applications where left-hand cutting direction is required.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for left-hand external turning on ferrous and non-ferrous materials in both roughing and finishing passes. The 95-degree lead angle supports longitudinal turning with positive cutting force direction. It is a non-coolant-through design, making it appropriate for flood or mist coolant environments where through-spindle coolant is not available. The Isoturn series is built to ISO 13399 standards, supporting digital tool assembly and presetter integration in modern CNC workflows.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction with DWLN toolholder style and negative rake geometry\u003c\/li\u003e\n\u003cli\u003e16mm x 16mm square shank for rigid setup in standard turning tool blocks\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003e95-degree lead angle suited to longitudinal external turning passes\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 tool data standards for digital tool management\u003c\/li\u003e\n\u003cli\u003eCompatible with a broad range of WNM insert grades and chipbreaker geometries\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts WNM-style inserts with a 0.375 inch inscribed circle.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the toolholder. Seat the shank fully in the tool block and torque the clamping screws according to the machine manufacturer's specifications for the block size. Insert clamping screw torque should follow ISCAR's published tooling guidelines for the WNM insert pocket.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: DWLN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\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\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: WNM\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\u003eShank Width\u003c\/strong\u003e: 16mm (0.63 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 16mm (0.63 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100mm (3.94 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 26mm (1.02 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 16mm (0.63 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.474 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3602587\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51753117810994,"sku":"3602587","price":155.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2a9b08e4b1d897b2a7d8cf62d85728e.jpg?v=1788932979","url":"https:\/\/voomisupply.com\/products\/iscar-3602587-dwln-indexable-turning-toolholder-16mm","provider":"Voomi Supply","version":"1.0","type":"link"}
