It is a single-sided, right-hand insert with a positive rake angle of 10 degrees and a 15-degree relief angle, designed for face and shoulder milling operations. The insert features a CVD-applied TiAlN and TiN dual coating for wear resistance and thermal stability under continuous cutting loads. With 4 cutting edges and a D57 chip breaker geometry, it is sized at an inscribed circle of 0.375 inches and a thickness of 0.156 inches. Installation is performed by qualified machinists or toolroom technicians using a screw-clamping method compatible with WALTER M4000 cutter bodies.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling of steel and cast iron workpieces across P and K material grade applications. The D57 chip breaker geometry is optimized for moderate to roughing depth-of-cut conditions, with a maximum depth of cut reaching 0.375 inches (9.52 mm). It is appropriate for use in production machining environments including CNC milling centers where consistent chip control and edge life are priorities. The M4000 cutter series compatibility makes it a straightforward drop-in selection for shops already running that platform.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiAlN and TiN dual coating for extended tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges per insert for improved cost-per-edge economy\u003c\/li\u003e\n  \u003cli\u003eD57 chip breaker geometry supports controlled chip formation across a range of feed rates\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (10 degrees) reduces cutting forces and heat generation\u003c\/li\u003e\n  \u003cli\u003e0.031-inch (0.80 mm) corner radius balances edge strength with surface finish capability\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method ensures secure, repeatable seating in M4000 cutter bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the WALTER M4000 cutter series.

Power down and de-energize the machine spindle before any insert change. Use the appropriate Torx or hex key to seat and torque the clamping screw into the M4000 pocket; follow the cutter body manufacturer torque specification for the screw size used. Inspect the insert pocket seat and screw threads for debris or damage before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SDMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: WKP35G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P35; K35\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; TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches (0.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (9.52 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.375 inches (9.52 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.375 inches (9.52 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.156 inches (3.97 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.375 inches (9.52 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 09T3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: D57\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel; Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: M4000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI; ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.007 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: WALTER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7170575\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":52108752617778,"sku":"7170575","price":320.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7d1ce605955110b3172d557fd4d8aa8.jpg?v=1790075103","url":"https:\/\/voomisupply.com\/products\/walter-7170575-milling-insert-sdmt09t3zdr-d57-wkp35g-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
