Built from steel with a 3\/4 inch square shank, this toolholder accepts DN..43. series inserts secured by a clamp-and-screw holding method. At 4.5 inches overall length with a head length of 1.38 inches and a back-of-bar to cutting edge distance of 1 inch, it provides a rigid, repeatable setup for right-hand turning passes. Licensed machinists and CNC programmers will recognize the MDJN designation as a 3-degree lead angle geometry suited to moderate depth-of-cut applications.\u003c\/p\u003e\n\u003cp\u003eThe 1000110 is intended for right-hand turning operations in production and job-shop environments. The negative rake geometry reduces insert edge chipping on interrupted cuts and harder workpiece materials. It is well-suited to steel and cast iron turning where insert edge strength matters more than cutting force reduction. The clamp-and-screw retention keeps the insert seated securely under high feed rates. No coolant-through capability is present, so external coolant delivery is required when flood cooling is used.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMDJN style with 3-degree lead angle for right-hand turning passes\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry for stronger insert edge on interrupted cuts and harder materials\u003c\/li\u003e\n  \u003cli\u003eClamp-and-screw insert holding method for secure, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch square shank compatible with standard lathe tool blocks and quick-change posts\u003c\/li\u003e\n  \u003cli\u003eAccepts DN..43. inserts with 1\/2 inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eSteel toolholder body for rigidity and durability in production turning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept DN..43. series inserts with a 1\/2 inch inscribed circle.

Ensure the machine spindle is fully stopped and the turret or tool post is locked out before changing the toolholder or insert. Torque the clamp screw to the insert manufacturer's specification using the appropriate Torx or hex key. Verify tool centerline height with a reference gauge before commencing the first cut, as MDJN geometry is sensitive to height offset errors.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MDJN\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\u003eInsert Compatibility\u003c\/strong\u003e: DN..43.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\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\u003eShank Width\u003c\/strong\u003e: 0.7500 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.7500 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5000 inches (4-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.3800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1.0000 inches\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: 0.75 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: 1000110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737845662002,"sku":"1000110","price":321.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/442e61687ab55675ae2e3837198e1bef.jpg?v=1788794240","url":"https:\/\/voomisupply.com\/products\/hertel-1000110-mdjn-indexable-turning-toolholder-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
