Part of the Kenloc series, it features a clamp-and-screw insert holding method that provides rigid, repeatable insert positioning under heavy cutting loads. The toolholder accepts DN..43. style inserts with a 0.5000-inch inscribed circle, making it suited for steel, cast iron, and other ferrous materials where negative rake geometry is preferred for edge strength and insert longevity. The 3\/4-inch square shank and 4.5-inch overall length are standard for most tool turrets in this size class.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is intended for use in production turning environments including job shops, contract machining operations, and maintenance facilities running general-purpose turning programs. The left-hand orientation positions the cutting edge for specific tool station assignments on multi-turret or gang-tooled lathes. A 3-degree lead angle provides controlled chip direction and is commonly specified for shoulder turning and medium-depth facing passes. Licensed machinists and CNC programmers specify this style for applications requiring consistent tool nose geometry with quick insert changes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand MDJN toolholder style with negative rake for increased insert edge strength\u003c\/li\u003e\n  \u003cli\u003eKenloc clamp-and-screw holding method for rigid insert seating and repeatability\u003c\/li\u003e\n  \u003cli\u003eAccepts DN..43. inserts with a 0.500-inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch square shank fits standard tool turret pockets in this size class\u003c\/li\u003e\n  \u003cli\u003e4.5-inch overall length with a 1.38-inch head length for compact turret clearance\u003c\/li\u003e\n  \u003cli\u003eSteel toolholder construction for durability in continuous and interrupted cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept DN.. 432 style inserts as specified by the manufacturer.

Power down and lock out the machine spindle before mounting or removing the toolholder from the turret. Torque the turret clamping screws to the machine manufacturer's specification, not to a generic value. Insert seating surfaces should be clean and free of chips before installing a new insert to maintain proper tool nose radius alignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MDJN\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\u003eSeries\u003c\/strong\u003e: Kenloc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DN..43. \/ DN.. 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\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.75 inches\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: 4.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.38 inches (34.93 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.0000 inches (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7796 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1096253\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738489585970,"sku":"1096253","price":240.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93cd6fcfdadafce19ea0aa0376c3d02d.jpg?v=1788800209","url":"https:\/\/voomisupply.com\/products\/kennametal-1096253-lh-mdjn-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
