Manufactured from uncoated ceramic with a bright finish, this triangular insert features a 7\/32 inch (0.2190 inch) inscribed circle, a 1\/64 inch (0.0156 inch) corner radius, and a 60-degree included angle. The positive rake geometry and 11-degree relief angle reduce cutting forces and support stable chip formation at elevated cutting speeds. It belongs to ISCAR's Isoturn series and is held in place by a clamp-style toolholder. Licensed machinists and CNC operators in production and job-shop environments are the primary installers of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for turning cast iron workpieces, where ceramic cutting materials excel due to their hardness and thermal resistance at high surface speeds. It carries an H and K primary workpiece material code per ISO 13399, covering grey cast iron and other cast iron grades. The Isoturn series designation indicates compatibility with standard TPG clamp-style toolholders. With a maximum depth of cut of 1.50 mm (0.0590 inch) and an insert length of 9.60 mm (0.3780 inch), it is suited to finishing and light-to-medium roughing passes where dimensional accuracy and surface finish are the priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUncoated ceramic insert material for high-speed cast iron turning without coolant-dependent performance\u003c\/li\u003e\n  \u003cli\u003eTPG insert style with positive rake for reduced cutting forces and clean chip evacuation\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular shape provides three usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003e1\/64 inch corner radius balances edge strength with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eClamp holding method compatible with standard TPG toolholder pockets\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 for tooling data interchange and CAM system integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in clamp-style TPG toolholders with a matching 60-degree triangular insert pocket.

Part of the ISCAR Isoturn series; consult ISCAR Isoturn toolholder documentation for confirmed holder pairings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert installation and indexing should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Use the correct clamp screw and torque tool specified by the toolholder manufacturer — do not over-tighten or substitute hardware. Inspect the insert pocket seat for debris or damage before seating the insert. Ceramic inserts are brittle; avoid interrupted cuts or conditions that produce high mechanical shock unless the application has been confirmed suitable by the toolholder and insert manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IN22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 7\/32 inch (0.2190 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 9.60 mm (0.3780 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch (0.0938 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.50 mm (0.0590 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Codes H, K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.94 inches L x 1.69 inches W x 0.47 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.033 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5791517\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51732709572914,"sku":"5791517","price":173.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d0d8937d42f5a58f077284921db51bd.jpg?v=1788745925","url":"https:\/\/voomisupply.com\/products\/iscar-5791517-tpg731t-ceramic-turning-insert-7-32-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
