It carries the TPCB2201 insert style designation with the KC5010 manufacturer grade, a micrograin carbide substrate with a PVD-applied Titanium Nitride (TiN) coating. The 60-degree triangular geometry provides a reliable cutting edge profile suited for finishing and semi-finishing passes. With a corner radius of 0.002 inches and an inscribed circle diameter of 0.25 inches, this insert is built for tight-tolerance bore work where surface finish and dimensional accuracy are critical. Machining professionals and toolroom technicians install this insert in compatible TPCB-style boring bar holders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal boring applications on ferrous and non-ferrous materials where a sharp, wear-resistant edge is required. The TiN coating extends tool life by reducing friction and resisting built-up edge, making it effective on steel and cast iron workpieces in both production and job-shop environments. The 11-degree relief angle reduces rubbing along the bore wall, supporting clean cuts at moderate depths of cut. It is typically used in small-diameter boring bars on CNC turning centers, manual lathes, and dedicated boring machines handling precision component work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for high hardness and edge integrity\u003c\/li\u003e\n  \u003cli\u003eKC5010 grade with PVD Titanium Nitride coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003e60-degree triangle (TPCB2201) geometry for multi-edge efficiency\u003c\/li\u003e\n  \u003cli\u003e0.002 inch corner radius for fine-finish boring applications\u003c\/li\u003e\n  \u003cli\u003e11-degree relief angle minimizes bore wall contact and reduces deflection\u003c\/li\u003e\n  \u003cli\u003e0.25 inch inscribed circle diameter fits standard small-bore toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TPCB-style insert boring bar holders that accept a 1\/4 inch inscribed circle triangular insert with a 0.096 inch thickness and a 0.130 inch hole diameter.

Ensure the machine spindle is fully stopped and the turret or boring bar is secured before changing inserts. Inspect the pocket seat and clamp for wear or debris before seating the insert, as contamination affects insert stability and bore accuracy. Follow the toolholder manufacturer torque guidelines for clamping screws to avoid insert fracture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPCB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 2201\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0960 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\u003eHole Diameter\u003c\/strong\u003e: 0.1300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1937568\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729580196146,"sku":"1937568","price":158.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b54a9e94517448a4b9a7d60618c0f82.jpg?v=1788706351","url":"https:\/\/voomisupply.com\/products\/kennametal-1937568-boring-insert-tpcb2201-kc5010-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
