It features a negative rake geometry and a 15-degree lead angle, making it well-suited for heavy interrupted cuts and general-purpose external turning operations. The toolholder accepts SN..43. series inserts and uses a clamp-and-screw insert holding method for secure, repeatable seating. The square shank measures 0.75 inches wide by 0.75 inches tall, with an overall length of 4.5 inches. Construction is steel throughout. Machinists and CNC operators working in production and job-shop environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for external turning applications on lathes and turning centers where a left-hand cutting orientation is required. The negative rake configuration performs reliably with carbide inserts on ferrous and non-ferrous materials. The 15-degree lead angle helps direct cutting forces toward the chuck, reducing deflection on slender workpieces. It is a single-purpose, non-coolant-through tool suited to dry or flood-coolant setups using external nozzles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting orientation for operations requiring reverse tool travel\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry for improved edge strength on carbide inserts\u003c\/li\u003e\n\u003cli\u003eClamp and screw insert retention for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eAccepts SN..43. series inserts with a 0.5 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity and durability in production environments\u003c\/li\u003e\n\u003cli\u003eNon-coolant-through design compatible with external flood-coolant delivery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept SN..432 series indexable inserts with a 0.5 inch inscribed circle.

Ensure the lathe or turning center is fully powered down and the spindle is locked before mounting or removing the toolholder. Seat the toolholder squarely in the tool post or turret and torque the clamping bolts to the machine manufacturer specifications. Insert installation should follow the insert manufacturer torque guidelines for the clamping screw to avoid cracking the insert or damaging the pocket.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MSKN\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\u003eLead Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1 inch\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\u003eInsert Compatibility\u003c\/strong\u003e: SN..43.\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\u003eSeries\u003c\/strong\u003e: Multi-Option\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 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: 1000137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735768432946,"sku":"1000137","price":251.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45c7b6b0c8784e86c071e516a22f3cd2.jpg?v=1788774043","url":"https:\/\/voomisupply.com\/products\/hertel-1000137-lh-mskn-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
