Part of the Kenclamp series, it accepts DN..33. negative-rake inserts and holds them securely via a top-clamp mechanism. The shank measures 0.75 inches wide by 0.75 inches tall, with an overall length of 4.5 inches. The head length is 1.25 inches, and the back-of-bar to cutting edge distance is 1.0 inch. The 3-degree lead angle geometry promotes controlled chip flow and reduces cutting forces. The toolholder body is machined from steel for rigidity under interrupted cuts and continuous turning passes. Installed by CNC machinists and toolroom technicians, this holder is suited for production turning applications requiring repeatable insert indexing.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for use in external turning operations where a negative-rake insert geometry is specified. The DDJN style positions the insert at a 3-degree lead angle, making it appropriate for straight turning and facing applications with moderate to heavy depth-of-cut requirements. The 0.75-inch square shank fits standard lathe tool posts and CNC turret stations sized for that cross-section. Coolant-through capability is not available on this holder, so flood or mist coolant delivery from an external source is the standard approach. The complete insert compatibility designation is DN.. 332, and the insert inscribed circle measures 0.375 inches (3\/8 inch).\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand DDJN toolholder style with 3-degree lead angle for controlled chip direction\u003c\/li\u003e\n\u003cli\u003eAccepts DN..33. negative-rake inserts; complete compatibility designation DN.. 332\u003c\/li\u003e\n\u003cli\u003e0.75-inch by 0.75-inch square steel shank fits standard turret and tool-post stations\u003c\/li\u003e\n\u003cli\u003eTop-clamp (Kenclamp) insert holding method for positive insert seating and quick indexing\u003c\/li\u003e\n\u003cli\u003eOverall length of 4.5 inches with a 1.25-inch head length\u003c\/li\u003e\n\u003cli\u003eNo coolant-through; compatible with external flood or mist coolant delivery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with DN..33. series negative-rake indexable inserts; complete insert compatibility designation is DN.. 332 with an insert inscribed circle of 0.375 inches.

Torque the clamping screws per the machine-tool manufacturer's specifications for the turret station size. Verify insert seating and clamp engagement before resuming cutting operations. Follow the machine tool manufacturer's guidelines and applicable shop-safety procedures for tool-change operations.\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: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Kenclamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DN..33.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Insert Compatibility\u003c\/strong\u003e: DN.. 332\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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\u003eShank Width\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.75 inches\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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.0 inch\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: 0.71 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2273014\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727821209906,"sku":"2273014","price":232.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b172f1bf55e6b779a172b56fa3ec2a8.jpg?v=1788683027","url":"https:\/\/voomisupply.com\/products\/kennametal-2273014-ddjn-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
