It is designed for external and internal turning operations on CNC lathes and turning centers. The insert features a triangular shape (60-degree included angle) with a positive rake geometry and a neutral hand orientation. The inscribed circle measures 3\/8 inch (0.3750 inch), insert length is 16.50 mm (0.6496 inch), and the corner radius is 1\/64 inch (0.0160 inch). Installation uses a screw-on holding method. This insert is used by machinists and CNC operators performing precision turning on a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning operations on stainless steel (M), non-ferrous metals (N), superalloys and high-temperature materials (S), and cast materials (K) as secondary application. The HC210 grade with TiN PVD coating provides wear resistance and edge stability at moderate to high cutting speeds. The maximum depth of cut is 1.25 mm (0.0492 inch). The TCMT32 series is commonly found in production turning environments, job shops, and aerospace or medical component machining where controlled chip formation and surface finish are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiN PVD coating for wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eHC210 manufacturer grade, material grades C2 and C4\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular insert shape with positive rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method for secure, repeatable indexing\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 1\/64 inch (0.0160 inch) for detail turning and controlled surface finish\u003c\/li\u003e\n  \u003cli\u003eT chip breaker geometry for effective chip control across primary workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw-on replacement for TCMT3251LF-style toolholders accepting a 3\/8-inch inscribed circle triangular insert with a clearance code C and tolerance code M.

Ensure the machine spindle is fully stopped and the tool is secured in a safe position before indexing or replacing inserts. Use the appropriate torque driver for the screw-on clamp screw to avoid over-tightening, which can crack the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before seating a 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: TCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HC210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eChip Breaker\u003c\/strong\u003e: T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.50 mm (0.6496 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0160 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch (4.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 32.51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: M (Stainless Steel), N (Non-Ferrous), S (Superalloys)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: K (Cast Materials)\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: 0.1 pounds\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: 1001140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746450669874,"sku":"1001140","price":356.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/245e3828155d688bba9a83bba079833d.jpg?v=1788870373","url":"https:\/\/voomisupply.com\/products\/hertel-1001140-turning-insert-tcmt3251lf-hc210-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
