It is built for external turning operations on CNC lathes and manual turning centers. The toolholder accepts DNMG 432 inserts and uses a dual-clamp insert-holding method for secure, repeatable insert positioning. The 1-inch by 1-inch square shank seats firmly in standard toolpost and turret blocks. With a 93-degree lead angle and an overall length of 6 inches, this holder suits a wide range of turning profiles where left-hand cutting direction is required. Installation is performed by qualified machinists or CNC setup technicians.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for turning applications across a broad range of workpiece materials, including steel, stainless, cast iron, non-ferrous metals, high-temperature alloys, and other materials corresponding to ISO material codes H, K, M, N, P, and S. It is designed for production and job-shop environments where consistent insert indexing and rigid clamping are priorities. The 1.65-inch head length and 1.25-inch back-of-bar to cutting-edge dimension suit standard turning setups requiring moderate reach and positive clearance geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction with a -6 degree negative rake angle for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eDual-clamp insert-holding method provides rigid, repeatable seating of DNMG 432 inserts\u003c\/li\u003e\n\u003cli\u003e1-inch by 1-inch square shank fits standard lathe toolpost and turret block slots\u003c\/li\u003e\n\u003cli\u003e93-degree lead angle suits shoulder-turning and profiling passes\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility covers ISO codes H, K, M, N, P, and S\u003c\/li\u003e\n\u003cli\u003eSteel toolholder body provides durability under interrupted cuts and heavy feeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts DNMG 432 inserts with a 3\/8-inch inscribed circle.

Power down and lock out the machine spindle before changing inserts or mounting the holder in the turret. Ensure the shank seating surfaces and turret pocket are clean and free of chips before tightening. Follow the machine tool manufacturer torque guidance for turret clamping screws; do not use clamping force beyond the holder manufacturer recommendations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: DDJN\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\u003eRake Angle\u003c\/strong\u003e: -6 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DNMG 432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: DN43 \/ DN44\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 Holding Method\u003c\/strong\u003e: Dual Clamp\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: 1.65 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\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\u003eWeight\u003c\/strong\u003e: 1.64 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02569289\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558948077874,"sku":"02569289","price":190.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a403e31ec4f7347f0ed97229bf3d4ad9.jpg?v=1786423810","url":"https:\/\/voomisupply.com\/products\/seco-02569289-lh-ddjn-turning-toolholder-dnmg-432","provider":"Voomi Supply","version":"1.0","type":"link"}
