Built from steel with a 1 x 1 inch square shank and an overall length of 6 inches, it accepts DN..54. series inserts secured by a clamp and screw holding method. The 3-degree lead angle and 1.47-inch head length position the insert for stable, repeatable cuts on ferrous and non-ferrous materials. Licensed machinists and CNC operators specify this holder for production turning where consistent insert indexing and rigid clamping are required.\u003c\/p\u003e\u003cp\u003eThis toolholder suits external turning applications in both job shop and production environments where a left-hand approach angle is dictated by the setup. The MDJN style is a common configuration for straight and shoulder turning passes. The 5\/8-inch (0.625 inch) insert inscribed circle and DN..54. insert compatibility make it a standard choice for medium to heavy stock removal on conventional and live-tooling lathe setups. It is not configured for coolant-through delivery and is intended as a single-application, non-multi-use holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand MDJN toolholder style with 3-degree lead angle for directional turning control\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry reduces cutting forces on rigid, stable workpiece setups\u003c\/li\u003e\n\u003cli\u003e1 x 1 inch square steel shank provides strong clamping surface in standard tool blocks\u003c\/li\u003e\n\u003cli\u003eClamp and screw insert retention ensures secure indexing under interrupted and continuous cuts\u003c\/li\u003e\n\u003cli\u003eAccepts DN..54. series inserts with a 5\/8-inch inscribed circle for broad insert availability\u003c\/li\u003e\n\u003cli\u003eBack-of-bar to cutting edge distance of 1.25 inches for predictable tool offset entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with DN..54. series inserts (DN.. 543 complete insert compatibility).

Ensure the machine spindle is fully stopped and all energy is locked out before mounting or adjusting the toolholder in the turret or tool post. Secure the shank firmly in the tool block to the machine manufacturer's clamping specification before indexing any insert. Inspect insert seating and clamp screw torque each time an insert is indexed to maintain dimensional accuracy and safe operation.\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: Left 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: 1.47 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: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DN..54.\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\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 1.8 pounds\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: 1000113\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749272650034,"sku":"1000113","price":295.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bf12f5a8d09120af64e66a04a45f91a.jpg?v=1788903872","url":"https:\/\/voomisupply.com\/products\/hertel-1000113-lh-mdjn-negative-rake-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
