It features a 0.75 inch square shank (0.75 inches wide by 0.75 inches tall) and an overall length of 4.5 inches. The toolholder uses a clamp-and-screw insert holding method and is engineered to accept TN..33. series inserts with a 0.375 inch inscribed circle. Built from steel, it delivers the rigidity required for interrupted cuts and high-feed roughing passes. Installed by machinists and toolroom technicians, this holder is a standard fit for production turning applications.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for external turning operations in both job-shop and production environments. The neutral hand orientation makes it adaptable to a range of toolpost and turret configurations without favoring a particular cut direction. The head length of 1.16 inches and the back-of-bar to cutting-edge distance of 0.375 inches position the insert for consistent tool geometry across standard turning setups. It is part of the HERTEL Multi-Option series, which is designed to provide tooling flexibility across varying material and depth-of-cut requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNeutral hand orientation for flexible turret and toolpost mounting\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle of -10 degrees for strength in heavy and interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eClamp-and-screw insert holding method for secure seating under high cutting loads\u003c\/li\u003e\n  \u003cli\u003eAccepts TN..33. series inserts (TN.. 332 complete compatibility) with 0.375 inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity and durability in production turning\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through channels, simplifying setup on standard turning centers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept TN..33. series inserts, with complete insert compatibility listed as TN.. 332.

Power down and lock out the machine before mounting or removing the toolholder from the turret or toolpost. Ensure the shank seating surfaces are clean and free of chips before tightening the clamping bolts to the machine manufacturer's specified torque. Confirm insert and toolholder compatibility before placing the tool in cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MTEN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TN..33.
