It features a rectangular shape with a 90-degree included angle, a positive rake geometry of 10 degrees, and a T-Land cutting edge style. The insert is PVD-coated with TiAlN and TiN layers for wear resistance across a range of workpiece materials. With 2 cutting edges, a corner radius of 2.00 mm, and a maximum depth of cut of 0.5512 inches, this insert is suited for demanding milling operations on steel, cast iron, stainless steel, non-ferrous metals, and superalloys including titanium. It is installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is designed for face milling and shoulder milling applications where consistent edge life and chip control are required. The M13 chip breaker geometry manages chip formation across primary workpiece materials coded P, K, and S, making it appropriate for both roughing and semi-finishing passes. It is held in the cutter body via a screw-clamping method and is a single-sided, right-hand insert. Compatible cutter series include R217.21-LP09 and R220.21-LP09 as specified by the manufacturer. Typical applications span aerospace, general machining, and automotive component manufacturing where mixed material runs are common.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide fine-grain substrate with PVD TiAlN and TiN dual coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eM13 chip breaker geometry supports steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 10 degrees with T-Land cutting edge reduces cutting forces\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert with a corner radius of 2.00 mm\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.5512 inches with a cutting edge effective length of 0.5512 inches\u003c\/li\u003e\n\u003cli\u003eScrew-held single-sided right-hand insert conforming to ISO standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with SECO cutter series R217.21-LP09 and R220.21-LP09 as stated by the manufacturer.

The machine spindle must be fully stopped and the machine locked out before changing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer when seating the clamping screw — do not overtighten, as this can fracture the carbide insert. Inspect the cutter body pocket and screw for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LPKT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: LPKT09T420TR-M13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LPKT09T420TR-M13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 09T420\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: F40M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide Fine Grain\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\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: 10 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: T-Land\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 2.00 mm (0.0787 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4.76 mm (0.1874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 9.50 mm (0.3740 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 14.00 mm (0.5512 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3740 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1772 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5512 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.5512 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R217.21-LP09 and R220.21-LP09\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\u003eStandard\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.012 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03212688\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560690188594,"sku":"03212688","price":33.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e37c50f86e08fc6a827af595a0aed4d.jpg?v=1786455782","url":"https:\/\/voomisupply.com\/products\/seco-03212688-milling-insert-lpkt09t420tr-m13-f40m-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
