It features a negative rake angle of -6 degrees and accepts WNMG 432 inserts, secured via a dual clamp holding method for rigid, repeatable positioning. The shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches, making it a standard square-shank toolholder suited for a range of lathe tool post and turret setups. Licensed machinists and CNC turning specialists are the primary installers of this toolholder.\u003c\/p\u003e\u003cp\u003eThis toolholder is built for turning applications across a wide range of workpiece materials, including steel, cast iron, stainless steel, aluminum, non-ferrous metals, and high-temperature alloys, reflected by its universal material compatibility codes H, K, M, N, P, and S. It is used in both production and job-shop environments where consistent insert positioning and dependable clamping are required. The left-hand cutting direction suits specific tool path orientations common in facing and turning passes where right-hand tooling is not practical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction with DWLN toolholder style for specific lathe orientation requirements\u003c\/li\u003e\n\u003cli\u003eNegative rake angle of -6 degrees for improved edge strength on harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eDual clamp insert holding method provides secure, vibration-resistant clamping of WNMG 432 inserts\u003c\/li\u003e\n\u003cli\u003e1 inch x 1 inch square shank for compatibility with standard lathe tool posts and turret stations\u003c\/li\u003e\n\u003cli\u003eUniversal primary workpiece material compatibility covers ferrous, non-ferrous, and superalloy materials\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design simplifies setup in standard non-coolant-fed tool stations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts WNMG 432 inserts with a 0.5 inch inscribed circle.
