Built from steel with a 0.75 inch square shank and an overall length of 4.5 inches, this toolholder accepts TN..33. series inserts secured by a clamp and pin holding method. The Multiple Lock series design provides rigid clamping and repeatable insert positioning. A negative rake angle of -10 degrees suits harder workpiece materials and interrupted cuts where edge strength is critical. Licensed machinists and CNC turning specialists are the primary installers of this toolholder.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for universal turning applications across a broad range of workpiece materials, including steel, stainless steel, cast iron, nonferrous alloys, aluminum, and superalloys — corresponding to ISO material groups P, M, K, N, H, and S. It is appropriate for both roughing and finishing passes in production turning environments where consistent insert seating and neutral cutting geometry are required. The 0.375 inch back-of-bar to cutting edge dimension allows straightforward tool-height setup on most standard turning tool posts and quick-change systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNeutral hand orientation for flexible use on both OD and face turning setups\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry (-10 degrees) for improved edge strength on hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003eClamp and pin insert holding for secure, repeatable seating of TN..33. inserts\u003c\/li\u003e\n\u003cli\u003e0.75 inch x 0.75 inch square shank fits standard turning tool post blocks\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across ISO groups H, K, M, N, P, and S\u003c\/li\u003e\n\u003cli\u003eSteel toolholder body for durability under continuous cutting loads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept TN..33. series indexable inserts with a 0.375 inch inscribed circle (insert size code TN33).
