The insert features a 60-degree triangular shape with a positive rake angle and an 11-degree relief angle, delivering a combination of edge sharpness and flank wear resistance suited to finishing and semi-finishing operations. At 0.25 inches inscribed circle and 11 millimeters in length, this is a compact, screw-on style insert designed for use in compatible TPMT-style toolholders. Installation and use are handled by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning operations on steel and stainless steel workpiece materials, corresponding to ISO P and M material groups. The HC335 grade and CVD multilayer coating make it well suited for continuous and light interrupted cuts at moderate to higher cutting speeds. The T-style chip breaker geometry supports controlled chip formation during finishing passes. The screw-on holding method provides secure clamping in standard TPMT-compatible toolholders used on CNC lathes and manual turning centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiC, TiCN, and TiN multilayer coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular insert shape with positive rake and 11-degree relief angle for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eT-style chip breaker for controlled chip evacuation during finishing and semi-finishing cuts\u003c\/li\u003e\n  \u003cli\u003eScrew-on mounting method for positive insert retention in TPMT-style toolholders\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.0492 inches (1.25 mm) suitable for finishing pass parameters\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0156 inches (1\/64 inch) for fine surface finish applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw-on replacement insert for TPMT-style toolholders compatible with the TPMT21.51 insert size code.

Use the appropriate Torx or hex key as specified by the toolholder manufacturer to seat and torque the clamping screw — do not overtighten, as carbide inserts are brittle and can crack under excessive clamp force. Inspect the toolholder pocket and seating surface for chips or debris before installing a new insert. Verify insert orientation and chip breaker direction before returning the machine to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HC335\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC, TiCN, TiN (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4331 inches (11 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 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\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\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: P (Steel)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: M (Stainless Steel)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0002 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: 1000697\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727139995954,"sku":"1000697","price":251.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bd4b34eda6e4480c912bcc6ab29cc11.jpg?v=1788673923","url":"https:\/\/voomisupply.com\/products\/hertel-1000697-turning-insert-tpmt2151lf-hc335-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
