Part of the Kennametal Kenloc series, this toolholder accepts CN inserts with a 1\/2-inch inscribed circle and is built for external turning operations on CNC lathes and manual turning centers. The shank measures 3\/4 inch wide by 3\/4 inch tall with an overall length of 4 inches. Constructed from steel, it delivers rigid insert clamping and repeatable edge positioning in high-volume production or job-shop turning applications. Licensed machinists and CNC setup technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for external longitudinal and facing operations on ferrous and non-ferrous workpieces. The MCLN style positions the insert at a negative rake angle, making it a practical choice for interrupted cuts, heavy roughing passes, and applications where insert security under cutting load is a priority. The clamp screw holding method provides a positive mechanical lock on the insert without requiring a top clamp that could interfere with chip flow in tight clearance situations. It fits standard square-shank tool blocks and quick-change toolpost systems that accept 3\/4-inch square shanks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMCLN toolholder style with right-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eClamp screw insert holding method for positive mechanical retention\u003c\/li\u003e\n  \u003cli\u003eAccepts CN-style inserts with a 1\/2-inch (0.5000 inch) inscribed circle\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry suited for interrupted cuts and heavy roughing\u003c\/li\u003e\n  \u003cli\u003e3\/4 x 3\/4 inch steel shank, 4 inches overall length\u003c\/li\u003e\n  \u003cli\u003eKenloc series construction for consistent insert seating and repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CN-style inserts, complete insert compatibility designation CN.. 432.

Ensure the machine spindle is fully stopped and the turret is in a safe indexed position before changing toolholders or inserts.
