Designed for screw-on toolholders, it features a 55-degree diamond insert shape with a positive rake geometry and neutral hand orientation. The inscribed circle measures 3\/8 inch (0.375 inches), the insert length is 0.4579 inches (11.63 mm), and the corner radius is 1\/64 inch (0.016 inches). The HC210 grade designation indicates a fine-grain carbide substrate suited to a range of turning applications. Licensed machinists and CNC operators install this insert in compatible screw-on toolholder systems for precision turning operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning operations on stainless steel, non-ferrous metals, and superalloys, corresponding to ISO workpiece material categories M, N, and S as primary materials, and cast iron (category K) as a secondary material. The maximum depth of cut is 0.0492 inches (1.25 mm), making this insert appropriate for finishing and light semi-finishing passes. It is used in production and job-shop environments on CNC lathes and manual turning centers where consistent surface finish and dimensional accuracy are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiN coating for wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (DPMT style) with positive rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eHC210 grade suitable for stainless, non-ferrous, and superalloy workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.016 inches supports fine surface finish on finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on DPMT-style toolholders accepting a 3\/8-inch inscribed circle diamond insert.

Ensure the machine spindle is fully stopped and the toolholder is removed or the turret is indexed to a safe position before changing inserts. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder manufacturer's specified method without overtightening, which can crack the carbide. Inspect the insert seat and shim for debris or damage before seating the new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DPMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HC210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4579 inches (11.63 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.016 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: M, N, S (ISO categories)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: K (ISO category)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1000456\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749088067890,"sku":"1000456","price":391.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e8b205631103ba33551a446ecbd857c.jpg?v=1788901953","url":"https:\/\/voomisupply.com\/products\/hertel-1000456-turning-insert-dpmt3251lf-hc210-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
