Manufactured to TDHB500 style specifications with grade KT315, this triangular insert features a 60-degree included angle, a 5\/32-inch inscribed circle, and a 0.002-inch corner radius suited for fine finishing cuts. The 15-degree relief angle reduces rubbing and supports cleaner chip evacuation in tight bore geometries. At 3\/64 inches thick, this insert fits standard TDHB-style boring bar pockets. It is sold individually but requires a minimum order of 5 units. Machinists and toolroom professionals working with ferrous materials in production environments are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis boring insert is applied in internal diameter finishing and light roughing operations on ferrous workpieces including cast iron and hardened steels. The KT315 cermet grade is appropriate for applications requiring smooth surface finishes and tight dimensional tolerances at moderate to high cutting speeds. Typical install scenarios include production turning cells and job shop boring operations where consistent tool geometry and wear resistance are critical. The C3, C7, and C8 material grade classifications indicate suitability across a range of cast iron, heat-resistant alloy, and steel finishing applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTDHB500 insert style with KT315 cermet grade for wear-resistant finishing performance\u003c\/li\u003e\n\u003cli\u003e60-degree triangular geometry provides three usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003e0.002-inch corner radius supports fine surface finish requirements\u003c\/li\u003e\n\u003cli\u003e15-degree relief angle reduces flank rubbing in small-diameter boring applications\u003c\/li\u003e\n\u003cli\u003e5\/32-inch inscribed circle (0.1600 inches) for standard TDHB pocket compatibility\u003c\/li\u003e\n\u003cli\u003eCermet substrate suitable for C3, C7, and C8 material classifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for TDHB-style boring bar tool holders accepting a 500-series triangular insert with a 5\/32-inch inscribed circle and 3\/64-inch seat thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Ensure the boring bar and machine spindle are fully stopped and the machine is locked out before seating or replacing the insert. Use the appropriate torx or hex key to secure the insert clamp to the manufacturer-specified feel-tight condition without over-torquing the retention screw. Inspect the insert pocket for chips or debris before seating the new insert to ensure full contact and correct geometry presentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TDHB500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KT315\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C7, C8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Triangle\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: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.1600 inches (5\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0470 inches (3\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.0950 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1937534\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750736625970,"sku":"1937534","price":177.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/faf19837270ccc6b8b96c7da180a85e7.jpg?v=1788919150","url":"https:\/\/voomisupply.com\/products\/kennametal-1937534-boring-insert-tdhb500-kt315-cermet","provider":"Voomi Supply","version":"1.0","type":"link"}
