It features a 1-1\/4 inch by 1-1\/4 inch square shank and an overall length of 6 inches, providing rigid support for insert-based external turning, facing, and profiling work. This toolholder accepts CN..432 series inserts and is part of the HERTEL Multi-Option series. It is intended for use by machinists and tool-and-die professionals working in production turning environments where consistent insert indexing and secure clamping are required.\u003c\/p\u003e\u003cp\u003eThis toolholder is suited for external turning applications on metal lathes in both production shop and job shop settings. The left-hand orientation positions the cutting edge for specific approach angles and feed directions that right-hand holders cannot address. Negative rake geometry distributes cutting forces across the insert edge, making it appropriate for interrupted cuts and harder workpiece materials where edge strength is a priority. It is a fixed, non-adjustable, single-purpose holder with no multi-use capability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand (LH) MCLN toolholder style for specific approach and feed direction requirements\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry for improved insert edge strength and durability in demanding cuts\u003c\/li\u003e\n\u003cli\u003eAccepts CN..432 indexable insert style for broad insert availability\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch by 1-1\/4 inch square shank for rigid machine tool interface\u003c\/li\u003e\n\u003cli\u003e6 inch overall length providing reach and stability in standard lathe turrets\u003c\/li\u003e\n\u003cli\u003ePart of the Multi-Option series for consistent fitment across compatible tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept CN..432 series indexable inserts.

Ensure the lathe spindle is fully stopped and locked out before mounting or removing toolholders from the turret. Use appropriate torque tools to secure the shank in the tool block or turret pocket without over-clamping. Confirm insert seating and clamp screw torque per the insert manufacturer's guidelines before resuming cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MCLN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CN..432\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: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Multi-Option\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Tool\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.19 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: 1002811\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754589978930,"sku":"1002811","price":266.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c67e6b60101dd6295d438af5e413c73f_7915268c-9c79-4699-a55b-3419f704d787.jpg?v=1788946890","url":"https:\/\/voomisupply.com\/products\/hertel-1002811-lh-mcln-indexable-turning-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
