It accepts TN..332 triangular inserts held by a combination clamp-and-screw method, providing rigid, repeatable insert location during turning passes. The toolholder features a negative rake geometry with a rake angle of -7 degrees, which is well-suited for interrupted cuts and harder workpiece materials where edge strength is a priority. The 0.5 x 0.5 inch shank mounts in standard OD turning tool posts and quick-change holders. Machinists and toolroom technicians are the primary installers of this toolholder in production and job-shop turning environments.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is part of the HERTEL Multi-Option series and is configured for neutral hand, meaning the cutting edge is centered and the holder can be used approaching from either direction without a left- or right-hand offset. It is intended for external turning operations on CNC and manual lathes. The 4.5-inch overall length and 1.13-inch head length suit standard tool-post clearances on small to mid-size turning centers. Compatible inserts are TN..332 triangular indexable inserts with a 0.375-inch inscribed circle diameter. The toolholder does not include coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNeutral hand MTCN toolholder style — no left or right offset required\u003c\/li\u003e\n  \u003cli\u003eAccepts TN..332 triangular indexable inserts with a 0.375-inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eNegative rake at -7 degrees for improved edge strength on harder materials\u003c\/li\u003e\n  \u003cli\u003eClamp and screw insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e0.5 x 0.5 inch shank fits standard OD turning tool posts\u003c\/li\u003e\n  \u003cli\u003eSteel toolholder body for rigidity and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TN..332 triangular indexable inserts (insert inscribed circle: 0.375 inches).
