It carries the KC735M manufacturer grade and features a Physical Vapor Deposition (PVD) titanium nitride (TiN) coating applied over a solid carbide substrate. The insert is square in shape with a 90-degree included angle, a neutral hand orientation, and four usable cutting edges. Each edge is ground to a sharp cutting edge style with a flat-top chip breaker and a positive rake geometry. The 20-degree relief angle and 1.00 mm corner radius make this insert suitable for general-purpose face milling and shoulder milling of steel and stainless steel workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in steel and stainless steel applications across both roughing and semi-finishing milling operations. The KC735M grade is optimized for primary workpiece materials classified under ISO material groups P (steel) and M (stainless steel). It is held in the cutter body by a screw-type clamping method. The insert seats in compatible SEHW-series indexable milling toolholders and is sized to a 0.5 inch inscribed circle. Typical installers are CNC machinists and toolroom technicians working with indexable milling cutters in production or job-shop environments. The maximum depth of cut reaches 0.5000 inch under appropriate cutting conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiN coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tool life and lower cost-per-edge\u003c\/li\u003e\n\u003cli\u003eSharp cutting edge style with flat-top chip breaker and positive rake geometry\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with right-hand and left-hand cutter bodies\u003c\/li\u003e\n\u003cli\u003e20-degree relief angle supports reduced cutting forces in ferrous milling\u003c\/li\u003e\n\u003cli\u003eScrew-type insert holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in SEHW-series indexable milling toolholders that accept a 0.5 inch inscribed circle square insert with a screw-type clamping method.

Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket and seating surfaces for chips or debris before seating the new insert. Do not exceed the cutter body's rated maximum depth of cut or spindle speed for the insert grade in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SEHW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SEHW1204AFN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SEHW43A6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\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: KC735M\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\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\u003eCutting Edge Style\u003c\/strong\u003e: Sharp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.00 mm (0.0394 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inches (0.22 mm)\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0168 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: 1157811\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732582826290,"sku":"1157811","price":233.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b37e1be561678258a13b1519467d2701.jpg?v=1788744660","url":"https:\/\/voomisupply.com\/products\/kennametal-1157811-milling-insert-sehw1204afn-kc735m-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
