The toolholder features a 1 x 1 inch square shank and an overall length of 6 inches, making it a standard-size choice for facing operations on CNC lathes and manual turning centers. It carries a negative rake angle of -6 degrees, which suits the geometry of DNMG-series inserts and promotes stable cutting forces during interrupted or continuous cuts. The steel construction provides the rigidity required for consistent insert indexing and repeatable tool life. Weighing 1.71 pounds, it fits standard toolpost and turret setups without special adapters in most cases.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is intended for facing applications in production turning environments, including both job shops and high-volume machining cells. It is compatible with DNMG 432 inserts with a 0.5 inch inscribed circle. The multi-use designation means it can be applied across a range of workpiece materials when paired with the appropriate DNMG insert grade. Machinists and CNC lathe operators working with steel, cast iron, and similar materials will find this holder a direct fit for standard OD turning and facing passes. The head length measures 1.55 inches, and the back-of-bar to cutting edge distance is 6 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDDJNR toolholder style with right-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eWedge clamping method secures DNMG 432 inserts for rigid, repeatable positioning\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle of -6 degrees suits DNMG insert geometry for facing and turning\u003c\/li\u003e\n  \u003cli\u003e1 x 1 inch square shank fits standard lathe turrets and toolposts\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides high rigidity for interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003eMulti-use designation supports a range of turning and facing applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with DNMG 432 inserts with a 0.5 inch inscribed circle.

Ensure the insert pocket and clamping wedge are clean and free of chips before seating a new DNMG 432 insert. Do not exceed the insert manufacturer's recommended cutting parameters for the insert grade selected. Torque the wedge clamp screw according to the insert manufacturer's specification found in the tooling documentation supplied with the insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: DDJNR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DNMG 432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Wedge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5 inches\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: 1.55 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 6 inches\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: -6 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Facing\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: 1.71 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153308\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5731066\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51730795954482,"sku":"5731066","price":222.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b3590289ed243e1a09db4a384ccfecc.jpg?v=1788722986","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5731066-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
