It uses a clamp screw holding method to secure the insert firmly during external turning operations. The shank measures 1 inch wide by 1 inch high, with an overall length of 6 inches. Compatible inserts seat on a 3\/8-inch (0.3750-inch) inscribed circle. This toolholder is manufactured from steel and is intended for installation and use by machinists and CNC turning professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 1096255 is suited for external turning applications where a left-hand MDJN-style holder is required. The MDJN toolholder style positions the insert at a negative rake angle, making it appropriate for heavier interrupted cuts and general-purpose turning on ferrous and non-ferrous materials. The Kenloc clamping system provides rigid insert retention, which is important in applications with interrupted cuts or higher feed rates. This holder fits standard square-shank toolpost setups commonly found on manual and CNC turning equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand MDJN toolholder style for external turning operations\u003c\/li\u003e\n\u003cli\u003eClamp screw insert holding method for secure, repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry supports heavier cuts and improved edge strength\u003c\/li\u003e\n\u003cli\u003e1 inch x 1 inch square shank fits standard toolpost configurations\u003c\/li\u003e\n\u003cli\u003eCompatible with DN-style inserts on a 3\/8-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eSteel construction provides rigidity and resistance to deflection under load\u003c\/li\u003e\n\u003cli\u003eNo coolant-through feature; relies on external coolant delivery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with DN.. 332 series inserts (complete insert compatibility: DN.. 332) with a 3\/8-inch inscribed circle.

Ensure the machine spindle is fully stopped and the machine is placed in a safe, locked-out state before changing the toolholder or insert. Secure the shank in the toolpost to the appropriate clamping torque specified by the toolpost manufacturer. Follow the insert manufacturer's guidelines for insert seating, clamping screw torque, and indexing intervals to avoid premature insert failure or toolholder damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MDJN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Kenloc\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DN.. 332\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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: 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.2500 inches\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: 1.68 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153308\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1096255\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738560987442,"sku":"1096255","price":247.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73db2eede192b8644b6b32c2dfc00958.jpg?v=1788801023","url":"https:\/\/voomisupply.com\/products\/kennametal-1096255-indexable-turning-toolholder-mdjnl163d","provider":"Voomi Supply","version":"1.0","type":"link"}
