Carrying the KCSM40 manufacturer grade, this insert features a dual PVD coating of TiAlN and TiN applied over a solid carbide substrate. The round RPPT insert shape provides 4 cutting edges with a neutral hand orientation, a positive rake angle of 18 degrees, and a chamfered and honed cutting edge style. It measures 0.187 inches thick with an inscribed circle of 0.472 inches. Insert holding is via screw, making it compatible with standard round-insert milling bodies designed for RPPT-style tooling.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for milling steel, stainless steel, superalloys, and titanium, covering ISO material groups P, M, and S. Its GDX chip breaker geometry is suited for moderate to aggressive cutting conditions where chip control and edge stability are critical. The 11-degree relief angle and positive rake geometry reduce cutting forces and heat generation at the insert edge. Typical install scenarios include face milling, shoulder milling, and circular milling operations on CNC machining centers in industrial manufacturing environments. The insert is single-sided and sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCSM40 solid carbide grade with PVD-applied TiAlN and TiN dual coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eRound RPPT insert shape with 4 cutting edges and neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eGDX chip breaker geometry optimized for steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 18 degrees reduces cutting forces and thermal load\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style improves edge integrity and reliability\u003c\/li\u003e\n\u003cli\u003eScrew-mount insert holding for secure, repeatable seating in compatible milling bodies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the Kennametal 7713VR12 cutter series.

Always index or replace inserts with the spindle powered down and the machine in a locked-out state per facility LOTO procedures. Inspect the insert pocket and clamping screw for wear or contamination before seating a new insert. Do not exceed the cutter body manufacturer's recommended speed and feed parameters for the RPPT insert pocket design.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCSM40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RPPT\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\u003eCoating\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GDX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 18 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.187 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.472 inches (12.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (0.17 mm nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1204\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: RPPT1204M0SGDX4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: RPPT1204M0SGDX4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01215 pounds\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: 6194540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740140175666,"sku":"6194540","price":38.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8ae7113508509c011268e39091f93b27.jpg?v=1788822798","url":"https:\/\/voomisupply.com\/products\/kennametal-6194540-kcsm40-round-milling-insert-rppt","provider":"Voomi Supply","version":"1.0","type":"link"}
