Built on a 1 inch by 1 inch steel shank with a 6 inch overall length, this toolholder features a 5-degree lead angle and accepts CN..43. series inserts secured by a clamp and screw holding method. It is intended for production turning environments where consistent insert indexing and rigid tool holding are required. The Series Multi-Option designation indicates broad insert interchangeability within the CN format family. Licensed machinists and CNC programmers working in job shop or production settings are the primary users.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for external turning applications on ferrous and non-ferrous workpieces where a negative rake cutting geometry is appropriate. The left-hand orientation positions it for specific spindle direction and approach configurations. The 1.2 inch head length and 1.25 inch back-of-bar to cutting edge dimension make it compatible with standard square-shank tool posts and quick-change tool blocks used in most engine lathe and turning center setups. No coolant-through capability is present, so external coolant delivery should be used when cutting conditions require it.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand MCLN toolholder style with 5-degree lead angle\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry for increased edge strength on harder materials\u003c\/li\u003e\n\u003cli\u003eAccepts CN..43. inserts held by clamp and screw method for positive retention\u003c\/li\u003e\n\u003cli\u003e1 inch by 1 inch steel shank for rigid setup in standard tool posts\u003c\/li\u003e\n\u003cli\u003e6 inch overall length with 1.2 inch head length\u003c\/li\u003e\n\u003cli\u003eBack of bar to cutting edge: 1.25 inches for predictable tool offset setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept CN..43. series indexable inserts, specifically compatible with CN.. 432 inserts as noted by the manufacturer.

The machine spindle must be stopped and the tool post or turret locked before mounting or indexing inserts. Clamp and screw insert retention components should be inspected for wear at each insert change. Follow the machine tool manufacturer's torque and clamping guidelines for the specific tool post or quick-change system in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MCLN\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\u003eLead Angle\u003c\/strong\u003e: 5 degrees\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: 1.2 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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CN..43.
