The holder features a 0.75 x 0.75 inch square shank and an overall length of 4.5 inches, placing the insert at a negative rake angle that improves edge strength and extends insert life in interrupted cuts and tough alloy materials. It accepts DN..332 series inserts. This toolholder is installed by machinists and CNC setup technicians in production and job shop turning environments.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for external turning applications on a range of workpiece materials where negative rake geometry is preferred for its durability under higher cutting loads. The MDJN style positions the insert to deliver stable, consistent chip control during roughing and semi-finishing passes. The square shank design provides rigid seating in standard OD turning tool blocks and quick-change turret stations commonly found in production turning setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand holder orientation for standard OD turning operations\u003c\/li\u003e\n\u003cli\u003eMDJN toolholder style with negative rake insert seating\u003c\/li\u003e\n\u003cli\u003eAccepts DN..332 series indexable inserts\u003c\/li\u003e\n\u003cli\u003e0.75 x 0.75 inch square shank for rigid turret and block mounting\u003c\/li\u003e\n\u003cli\u003e4.5 inch overall length for standard reach on most turning centers\u003c\/li\u003e\n\u003cli\u003ePart of the Multi-Option series for broad insert availability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept DN..332 series indexable inserts.

Power down and lock out the machine before mounting or removing the toolholder from the turret or tool block. Ensure the insert pocket and seating surface are clean and free of chips before indexing or replacing the DN..332 insert. Follow machine manufacturer torque guidelines for clamping screws and verify tool overhang is within the machine specification before resuming cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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..332\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches (114.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.315 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Multi-Option\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1002794\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755123769650,"sku":"1002794","price":328.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35f9b24bf670acd104ac6a6a94306de1_efb53dcf-b99b-4de7-967e-e2ffff4491f2.jpg?v=1788951369","url":"https:\/\/voomisupply.com\/products\/hertel-1002794-mdjn-negative-rake-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
