Built from steel, it accepts RN..64. series inserts held in place by a clamp and screw clamping method. The toolholder features a -5 degree rake angle and a 15-degree lead angle, providing stable, predictable cutting geometry suited for general-purpose turning of ferrous and non-ferrous materials. At 6 inches overall length with a 1.5 inch by 1.5 inch square shank, it fits standard tool blocks and quick-change holders common in production turning environments. Licensed machinists and CNC operators are the primary installers of this toolholder.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for use in production turning centers, engine lathes, and turret lathes where negative-rake insert geometry is preferred for heavier cuts and longer tool life. The MRGN style is commonly used in both roughing and finishing operations where controlled chip formation and insert rigidity are priorities. The 3\/4 inch insert inscribed circle supports a substantial cutting edge engagement suitable for moderate to heavy stock removal. The absence of coolant-through capability makes this toolholder appropriate for external turning applications where flood or mist coolant is applied conventionally.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand cutting orientation for standard OD turning setups\u003c\/li\u003e\n\u003cli\u003eNegative rake angle of -5 degrees with 15-degree lead angle for stable chip control\u003c\/li\u003e\n\u003cli\u003eClamp and screw insert retention system for secure, repeatable insert seating\u003c\/li\u003e\n\u003cli\u003e1.5 inch by 1.5 inch square steel shank fits standard tool block stations\u003c\/li\u003e\n\u003cli\u003eCompatible with RN..64. series round inserts with 3\/4 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003e6 inch overall length with 1.31 inch head length for rigid overhang characteristics\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept RN..64. series round indexable inserts with a 3\/4 inch inscribed circle.

Secure the toolholder in the tool block or turret station according to machine manufacturer torque guidelines before engaging the spindle. Ensure the machine is fully powered down and the spindle is locked before changing inserts or repositioning the holder. Follow shop safety protocols and applicable OSHA machine guarding requirements when working on turning equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MRGN\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\u003eRake Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1.5 inches\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: 1.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: RN..64.\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\u003eWeight\u003c\/strong\u003e: 0.38 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1000120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740959899954,"sku":"1000120","price":324.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2451193547499da0920a80b8a54e09d7.jpg?v=1788828609","url":"https:\/\/voomisupply.com\/products\/hertel-1000120-mrgn-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
