Built on a 1 x 1 inch square shank with an overall length of 6 inches, this toolholder uses a clamp-lock holding method to secure CN-series inserts rigidly during interrupted and continuous turning passes. The steel construction provides the rigidity needed for heavy stock removal. Coolant-through capability is not included. This holder is installed by machinists and CNC lathe operators working in production and job-shop turning environments.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for external turning operations where a left-hand cutting direction is required. The DCKN geometry positions the insert at a negative rake angle, which increases edge strength and makes it well-suited for harder workpiece materials and higher feed rates. The 1.3 inch head length and 1.25 inch back-of-bar to cutting-edge dimension allow for precise tool positioning. It accepts CN-type inserts with a 1\/4 inch inscribed circle, making insert sourcing straightforward across multiple manufacturers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eLeft-hand DCKN toolholder style with negative rake geometry for increased insert edge strength\u003c\/li\u003e\n\u003cli\u003eClamp-lock insert holding method for secure, repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003e1 x 1 inch square shank fits standard OD turning toolpost pockets\u003c\/li\u003e\n\u003cli\u003e6 inch overall length with 1.3 inch head length for reach and clearance in most lathe setups\u003c\/li\u003e\n\u003cli\u003eCompatible with CN-series inserts featuring a 1\/4 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity under heavy cutting loads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eAccepts CN.. 43.. series inserts including CNGA, CNGP, CNMA, CNMG, CNMM, and CNMP styles with a 1\/4 inch (0.2500 inch) inscribed circle.

Power down and lock out the machine spindle before seating or changing inserts. Ensure the shank is fully engaged and clamped in the toolpost or turret block to the depth recommended by the machine manufacturer. Follow standard shop safety practices when handling indexable inserts, as cutting edges are sharp.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: DCKN\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\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: 1.3 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\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp Lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CN.. 43..
