Built on the Kenclamp series platform, this toolholder features a -7 degree rake angle and a 27.5-degree lead angle, providing controlled chip formation and stable cutting geometry. The 1.25-inch by 1.25-inch steel shank offers rigid support during heavy interrupted cuts or continuous finish passes. It accepts DN..43. series inserts with a 0.50-inch inscribed circle diameter. A clamp-style insert holding method ensures secure seating and fast insert changes without removing the toolholder from the turret.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for external turning applications in production and job-shop environments where left-hand cutting direction is required. The DDQN geometry with negative rake is commonly applied when machining ferrous and hard materials where insert edge strength is a priority. Machinists and CNC programmers working on OD turning operations will find the 6.0-inch overall length and 1.38-inch head length appropriate for standard turret block setups. Coolant-through capability is not available on this model, so external coolant delivery applies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting orientation for DDQN-style external turning\u003c\/li\u003e\n\u003cli\u003eNegative rake at -7 degrees for increased insert edge strength\u003c\/li\u003e\n\u003cli\u003eClamp-style insert retention for fast, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eAccepts DN..43. inserts with a 0.50-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003e1.25-inch by 1.25-inch steel shank for rigid turret mounting\u003c\/li\u003e\n\u003cli\u003e27.5-degree lead angle geometry for controlled chip direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with DN..43. series indexable inserts (complete insert compatibility: DN.. 432) with a 0.50-inch inscribed circle diameter.

Power down and lock out the machine spindle before mounting or removing the toolholder from the turret. Verify insert seating and clamp torque according to your machine tool manufacturer specifications before beginning any cut. Do not exceed the rated shank dimensions of the turret pocket to maintain proper tool centerline height.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: DDQN\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\u003eRake Angle\u003c\/strong\u003e: -7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 27.5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DN..43.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Kenclamp\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: 2.65 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: 2273023\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727496249650,"sku":"2273023","price":266.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e0a57fce8d3af236e8ec6b60a8b2b95.jpg?v=1788678540","url":"https:\/\/voomisupply.com\/products\/kennametal-2273023-ddqn-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
