Built on the Clamp Lock series, it uses a top-clamp insert holding method to secure TN..33.. family inserts at a negative rake angle of -6 degrees, providing strong edge support when machining a wide range of workpiece materials. The steel shank measures 0.75 inches wide by 0.75 inches tall with an overall length of 4.5 inches. Installation is handled by machinists and CNC toolroom technicians setting up turning applications requiring left-hand cutting direction.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for general-purpose turning in both production and job-shop environments. The 90-degree lead angle and negative rake geometry make it appropriate for roughing and semi-finishing passes across universal workpiece material categories including steel, stainless, cast iron, non-ferrous, and superalloys. The 3\/8-inch insert inscribed circle and 1.18-inch head length position the cutting edge 1 inch back from the bar centerline, giving clearance in common gang-tool and turret setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction with DTGN toolholder style and 90-degree lead angle\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry (-6 degrees) for strong insert edge support during interrupted or heavy cuts\u003c\/li\u003e\n\u003cli\u003eClamp Lock top-clamp holding method secures inserts rigidly without set-screw interference\u003c\/li\u003e\n\u003cli\u003eCompatible with TN..33.. insert family including TNGA, TNMA, TNMG, TNMM, and TNMP styles\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity and durability in standard turning center toolposts and turrets\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility covering steels, stainless, cast iron, non-ferrous, and high-temp alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts TN..33.. series inserts including TNGA, TNMA, TNMG, TNMM, and TNMP with a 3\/8-inch inscribed circle.
