Built on the Kenclamp series platform, it features a 1 inch by 1 inch steel shank, a 6 inch overall length, and a -7 degree rake angle. The clamp-style insert holding method secures DN..43. series inserts with a 0.5 inch inscribed circle. This toolholder is used by machinists and toolroom technicians performing precision turning, facing, and profiling operations where insert indexability and rigid clamping are required.\u003c\/p\u003e\u003cp\u003eThe 2273021 is suited for use on engine lathes, CNC turning centers, and multi-axis machines requiring a left-hand toolholder orientation. Its 27.5-degree lead angle and 1.38 inch head length position the cutting edge 1.25 inches back from the bar, making it appropriate for general-purpose turning of ferrous and non-ferrous workpieces. No coolant-through capability is present, so external flood or mist coolant delivery should be used when required by the application.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDDQN toolholder style with left-hand orientation for correct insert presentation in left-hand turning setups\u003c\/li\u003e\n\u003cli\u003e-7 degree negative rake angle provides strong edge support for interrupted cuts and harder workpiece materials\u003c\/li\u003e\n\u003cli\u003e1 inch by 1 inch shank cross-section for rigid machine tool post or turret mounting\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method accepts DN..43. series inserts with 0.5 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003e6 inch overall length with 1.38 inch head length and 1.25 inch back-of-bar to cutting edge dimension\u003c\/li\u003e\n\u003cli\u003eSteel construction through Kennametal Kenclamp series for durability under continuous cutting loads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts DN..43. series indexable inserts with a 0.5 inch (1\/2 inch) inscribed circle; complete insert compatibility reference is DN.. 432.
