It carries an ANSI designation of TPET-321 and features an insert style of TPET with a positive rake geometry and an 11-degree relief angle. The inscribed circle diameter measures 0.3750 inches, thickness is 0.1250 inches, and the corner radius is 0.0156 inches (1\/64 inch). With three cutting edges on a single-sided configuration, this insert delivers consistent performance in milling applications where precision and tool longevity are critical. Installed by machinists and toolroom professionals in CNC and manual milling setups.\u003c\/p\u003e\u003cp\u003eThis insert is suited for milling steel in production and job-shop environments. It is designed as a screw-held, single-sided insert with a neutral hand orientation, making it straightforward to index and replace at the machine. The maximum depth of cut is 0.1250 inches, and the positive rake geometry helps reduce cutting forces on the workpiece. The TiN coating improves surface hardness and wear resistance, extending tool life in continuous and interrupted steel cutting applications. Compatible with HARVEY TOOL cutter series 81250 and 81260 as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiN coating for improved wear resistance on steel\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape (TPET style) with 60-degree included angle and positive rake geometry\u003c\/li\u003e\n\u003cli\u003eThree cutting edges, single-sided — indexes at the machine without removing the cutter body\u003c\/li\u003e\n\u003cli\u003e11-degree relief angle reduces rubbing and heat buildup during cut\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0156 inches (1\/64 inch) for controlled surface finish on steel workpieces\u003c\/li\u003e\n\u003cli\u003eScrew-held mounting method ensures secure clamping and repeatable edge positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with HARVEY TOOL cutter series 81250 and 81260.

Power down and lock out the spindle before indexing or replacing inserts. Use the correct torque driver or wrench for the clamping screw — do not overtighten, as carbide inserts are brittle and can crack under excessive clamping force. Inspect the insert pocket and seating surface for chips or debris before seating a new insert to ensure proper edge height and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPET\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: TPET-321\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\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\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 321\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.6500 inches\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\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Single Sided\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Common\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: 81250, 81260\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 60031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51736383684914,"sku":"60031","price":239.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4dcdafd5a7cb42df7da5d1ba0276e34d.jpg?v=1788777622","url":"https:\/\/voomisupply.com\/products\/harvey-tool-60031-solid-carbide-milling-insert-tin-tpet-321","provider":"Voomi Supply","version":"1.0","type":"link"}
