Built from steel with a 0.75 inch square shank and an overall length of 4.5 inches, it uses a clamp-lock insert holding method to secure negative-rake CN-style inserts at a rake angle of -6 degrees. A 95-degree lead angle positions the cutting edge for stable, chatter-resistant cuts. Licensed HVAC techs, plumbers, and machinists working in metalworking trades will recognize this as a workhorse toolholder suited for medium to heavy turning passes across a broad range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is intended for turning applications on a wide range of workpiece materials, including steels, stainless steels, cast irons, non-ferrous metals, heat-resistant superalloys, and other universal material groups. The left-hand cutting direction makes it the correct choice for applications that require right-to-left tool travel. It accepts CN..43. family inserts, giving shops flexibility in insert grade and geometry selection for roughing, semi-finishing, and finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cutting direction with 95-degree lead angle for stable entry and exit\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry at -6 degrees for increased insert edge strength on interrupted or heavy cuts\u003c\/li\u003e\n  \u003cli\u003eClamp-lock insert holding method for secure, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch x 3\/4 inch square steel shank fits standard lathe tool blocks and quick-change systems\u003c\/li\u003e\n  \u003cli\u003eCompatible with CN..43.. insert family including CNGA, CNGP, CNMA, CNMG, CNMM, and CNMP geometries\u003c\/li\u003e\n  \u003cli\u003eUniversal primary workpiece material rating covering material groups H, K, M, N, P, and S\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\/2 inch inscribed circle.
