Manufactured to the CDHB insert style in an 80-degree diamond shape, it carries the KT315 grade designation, which places it in the C3, C7, and C8 material grade categories. The insert measures 5\/32 inches inscribed circle (0.156 inches decimal), 0.040 inches thick, with a 0.007-inch corner radius and a 15-degree relief angle. These geometry characteristics make it well-suited for finishing and semi-finishing passes where dimensional accuracy and surface finish are the primary objectives. Cermet construction provides a hard, wear-resistant cutting edge that maintains sharpness longer than standard carbide grades in certain steel and cast iron applications.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in boring bars and boring heads configured for the CDHB insert style. It is typically applied in production and job-shop environments where close-tolerance bores are required in ferrous materials including medium-carbon steels, alloy steels, and hardened steels within the appropriate hardness range for cermet grades. The compact inscribed circle size of 0.156 inches suits small-bore applications where tool access is limited. Machinists and toolroom technicians working on tight-tolerance components will find this insert appropriate for light finishing depths of cut.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCDHB insert style with 80-degree diamond shape for rigid, low-vibration cutting geometry\u003c\/li\u003e\n\u003cli\u003eKT315 cermet grade rated for C3, C7, and C8 material categories\u003c\/li\u003e\n\u003cli\u003e0.007-inch corner radius suited for fine surface finish on finish boring passes\u003c\/li\u003e\n\u003cli\u003e15-degree relief angle reduces rubbing and supports clean bore wall contact\u003c\/li\u003e\n\u003cli\u003e0.156-inch inscribed circle for small-bore tooling setups\u003c\/li\u003e\n\u003cli\u003e0.040-inch insert thickness provides a compact profile in tight boring bar pockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for boring bars and holders configured to accept the CDHB insert style with a Series C designation.

Use the appropriate torque wrench and insert-seating tool recommended by the boring bar manufacturer to seat and secure the insert without over-torquing the clamping screw. Inspect the insert pocket for chips or debris before seating the new insert. Cermet inserts are brittle compared to carbide; avoid interrupted cuts, heavy feeds, or hammering the insert into the pocket.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CDHB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 120605\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KT315\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C7, C8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/32 inches (0.156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.083 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.007 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 1937511\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753997730098,"sku":"1937511","price":193.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e1e7b7456c3ea47d95f243b433cef4.jpg?v=1788942706","url":"https:\/\/voomisupply.com\/products\/kennametal-1937511-boring-insert-cdhb120605-kt315-cermet","provider":"Voomi Supply","version":"1.0","type":"link"}
