Built on the Kenclamp clamping platform, it accepts DN..43. series inserts and holds them securely via a top-clamp mechanism. The shank measures 1 inch wide by 1 inch tall, with an overall length of 6 inches and a head length of 1.25 inches. The 3-degree lead angle positions the insert for efficient cutting on standard OD turning passes. Constructed from steel, this toolholder delivers the rigidity required for productive metal removal with negative-rake insert geometries. Licensed HVAC techs and plumbers are not the audience here — this part is specified and installed by machinists, CNC programmers, and tool-crib managers in metal-cutting production environments.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for right-hand OD turning applications in both production and job-shop environments. The DDJN style accommodates DN..43. inserts with a 0.5-inch inscribed circle, making it compatible with a common family of negative-rake diamond inserts used in general-purpose steel and cast-iron turning. It is not configured for coolant-through delivery, so external coolant supply or flood coolant at the turret is the expected setup. Typical applications include facing, straight turning, and shoulder work where the 3-degree lead angle provides adequate chip clearance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDDJN toolholder style with right-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry for use with standard DN..43. series inserts\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert retention for secure holding under interrupted or heavy cuts\u003c\/li\u003e\n  \u003cli\u003e1 x 1 inch square shank fits standard OD turning turret stations\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 1.25-inch head length for reach flexibility\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity and resistance to deflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eAccepts DN..43. series indexable inserts with a 0.5-inch (1\/2 inch) inscribed circle.

The machine spindle must be stopped and the turret fully de-energized before seating or changing the toolholder. Torque the turret clamping bolts to the machine manufacturer specification — do not use values from this listing. Verify insert seating and clamp engagement before resuming cutting operations, and confirm tool offset entry in the CNC control matches the head length and cutting-edge position.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eRake\u003c\/strong\u003e: Negative\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\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\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: 1.25 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\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Kenclamp\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: 1.702 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: 1875136\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732461224242,"sku":"1875136","price":221.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ee32cf6568898bf9d1a5c7e5715866f.jpg?v=1788743025","url":"https:\/\/voomisupply.com\/products\/kennametal-1875136-ddjn-turning-toolholder-1x1-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
