It features a 1 x 1 inch square shank and an overall length of 6 inches, making it a standard-size holder suited for common lathe turret positions. The holder accepts TN..33. series triangular inserts secured by a combination clamp and screw holding method, providing rigid clamping force and repeatable insert positioning. Constructed from steel, this toolholder is built for production turning environments where insert changes and consistent edge presentation are a regular part of the workflow. Licensed machinists and CNC operators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is intended for external turning applications on steel, cast iron, and similar ferrous workpieces where a negative rake insert geometry is preferred for edge strength and tool life. The MTJN style provides a 3-degree lead angle, which helps control chip direction and reduces radial cutting forces in straight turning and facing passes. It is well suited for both roughing and finishing passes depending on the insert grade selected. The holder does not support coolant-through delivery, so flood or mist coolant must be applied externally at the cutting zone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard lathe setups\u003c\/li\u003e\n  \u003cli\u003eMTJN toolholder style with 3-degree lead angle for controlled chip flow\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry for increased insert edge strength\u003c\/li\u003e\n  \u003cli\u003eAccepts TN..33. triangular indexable inserts (3\/8 inch inscribed circle)\u003c\/li\u003e\n  \u003cli\u003eClamp and screw insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity in production turning environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept TN..33. series triangular indexable inserts with a 3\/8 inch (0.3750 inch) inscribed circle, specifically compatible with complete insert designation TN.. 332.

Before mounting or removing the holder, ensure the lathe spindle is fully stopped and the machine is in a safe, locked-out state per your facility lockout\/tagout procedure. Torque the turret clamp bolts evenly and confirm the shank is fully seated in the turret pocket before operation. Do not exceed the insert manufacturer's recommended depth of cut or feed rate for the selected insert grade.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MTJN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TN..33.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Multi-Option\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1000190\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731917013298,"sku":"1000190","price":229.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2994958768b41ca5065c64e7ff00d44.jpg?v=1788736566","url":"https:\/\/voomisupply.com\/products\/hertel-1000190-mtjn-indexable-turning-toolholder-1x1-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
