It accepts CN..32. series inserts held in place by a combination clamp and screw system, providing rigid insert seating under interrupted and continuous cut conditions. The shank measures 0.75 inches wide by 0.75 inches tall with an overall length of 4.5 inches, making it a compact, direct-mount holder suited to standard square-shank tool blocks. Steel construction gives it the rigidity and wear resistance expected in production turning environments. Licensed machinists, toolroom operators, and CNC setup technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for external turning applications where a left-hand cutting direction is required, such as turning toward a shoulder or working a part chucked in a configuration that favors left-hand tool entry. The 5-degree lead angle influences chip flow and helps reduce radial cutting forces. With a head length of 1.0 inch and a back-of-bar to cutting edge distance of 1.0 inch, it positions the insert predictably within standard MCLN geometric tolerances. It is a single-use toolholder, not configured for multi-use setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand MCLN holder geometry with 5-degree lead angle for controlled chip direction\u003c\/li\u003e\n\u003cli\u003eAccepts CN..32. series inserts with a 3\/8-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eClamp and screw insert retention for secure seating under heavy cuts\u003c\/li\u003e\n\u003cli\u003eSquare shank: 0.75 inches wide by 0.75 inches tall, overall length 4.5 inches\u003c\/li\u003e\n\u003cli\u003eSteel toolholder body for rigidity and long service life\u003c\/li\u003e\n\u003cli\u003eNo coolant-through passages — external coolant application only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with CN..32. series indexable inserts, specifically CN.. 322 geometry.

Before mounting or changing inserts, power down the machine and confirm the spindle is fully stopped. Secure the toolholder in a clean, properly sized tool block pocket and torque the clamping hardware according to the machine tool manufacturer and insert supplier specifications. Handle indexable inserts with care — use an insert seating tool rather than bare fingers to avoid edge chipping and personal injury.\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\u003eInsert Compatibility\u003c\/strong\u003e: CN..32.
