It carries a TiN coating applied via PVD process, which improves surface hardness and wear resistance during cutting operations. The insert measures 0.3126 inches wide, 0.0937 inches thick, and features an inscribed circle of 0.3752 inches. The neutral hand orientation and 11-degree relief angle suit it to a range of milling applications. Licensed machinists and toolroom technicians typically specify this insert for ferrous and non-ferrous material removal operations requiring consistent tool life.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling operations on materials falling under C2, C3, and C4 material grades, covering a broad range of cast irons, non-ferrous alloys, and general-purpose steels. The RPGB series geometry with a round insert shape provides a large cutting edge contact area, making it appropriate for both light and moderate depth-of-cut passes. Maximum depth of cut reaches 0.3808 inches. The ISO designation is RPGB070200, and the insert is held in place by a screw-type clamping method within compatible tool bodies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD TiN coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eRound insert shape (RPGB series) provides continuous cutting edge geometry\u003c\/li\u003e\n  \u003cli\u003e11-degree relief angle supports clean chip clearance during milling\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting method ensures secure, repeatable insert positioning\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.3808 inches suits a range of milling passes\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard RPGB tool body configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard service insert for milling tool bodies accepting RPGB-series round inserts with a screw-type holding method.

Use the correct torx or hex key specified by the tool body manufacturer when seating the clamping screw — do not overtighten. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Handle solid carbide inserts carefully to avoid chipping the cutting edge prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RPGB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\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\u003eISO Code\u003c\/strong\u003e: RPGB070200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3126 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3752 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3808 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1402 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 2.51.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0794 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1157540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748821565746,"sku":"1157540","price":223.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5e02cbba78b9ff29214c9ad4f217b14.jpg?v=1788899008","url":"https:\/\/voomisupply.com\/products\/kennametal-1157540-milling-insert-rpgb070200-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
