It carries a multilayer CVD coating — TiC, TiCN, and TiN — that provides a balance of wear resistance and toughness across a range of workpiece materials. The insert has a 3\/8 inch (0.3750 inch) inscribed circle, a 5\/32 inch (0.1563 inch) thickness, and a 3\/16 inch (0.1875 inch) corner radius. Its full-radius round shape distributes cutting forces evenly, reducing the risk of chipping on interrupted cuts. Licensed machinists and CNC setup technicians are the primary installers of this insert type.\u003c\/p\u003e\u003cp\u003eThis insert is suited for medium machining of steel and stainless steel as primary workpiece materials, with secondary application on cast iron and special or super alloys. The neutral hand orientation makes it compatible with both right-hand and left-hand tooling configurations. The RCMT32.5 ANSI code and RCMT097300 ISO code confirm broad international toolholder compatibility. The screw-on holding method provides positive insert retention under high cutting forces. Typical applications include external and internal turning, shoulder facing, and shallow boring passes at moderate depths of cut up to 0.0492 inch (1.25 mm).\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRound RCMT insert shape with full radius for even force distribution across 360 degrees\u003c\/li\u003e\n\u003cli\u003eKC850 grade with multilayer CVD TiC\/TiCN\/TiN coating for moderate wear resistance and high toughness\u003c\/li\u003e\n\u003cli\u003e4 usable cutting edges per insert with honed cutting edge style\u003c\/li\u003e\n\u003cli\u003ePositive rake and positive side clearance (clearance code C) for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method with 0.1732 inch hole diameter for secure toolholder engagement\u003c\/li\u003e\n\u003cli\u003eMulti-use application: turning, facing, and boring from a single insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for screw-on RCMT-style toolholders conforming to ANSI and ISO standards.

Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the toolholder pocket for chips or debris before seating the new insert, as contamination in the pocket will affect insert seating and surface finish. Do not overtighten the clamp screw beyond the toolholder manufacturer's specified torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: RCMT32.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: RCMT097300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: R - Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC850\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC, TiCN, TiN (CVD Multilayer)\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: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inch (1.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive (Code C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Common, Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K), Special and Super Alloys (S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\u003c\/strong\u003e: Turning, Facing, Boring\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 insert per package (minimum order quantity: 5)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0077 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: 1162412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732777861426,"sku":"1162412","price":132.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/597c987f7c1cc05ebb36be05d312bea4.jpg?v=1788746694","url":"https:\/\/voomisupply.com\/products\/kennametal-1162412-rcmt325-kc850-round-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
