Conforming to ISO code TPGT110204-MM4 WSM01, this insert features a triangular shape with a 60-degree included angle and a positive rake geometry at 7 degrees. The substrate is coated via PVD process with TiAlN, Al2O3, and ZrN layers under the proprietary WSM01 grade designation. Key cutting geometry includes a 0.4 mm corner radius, an 11 mm insert length, and a 6.35 mm inscribed circle. With three available cutting edges and a honed cutting edge style, this insert is suited for finishing and semi-finishing passes. Installation uses a screw-holding method.\u003c\/p\u003e\u003cp\u003eThis insert is optimized for primary use in stainless steel, superalloys, and titanium workpiece materials, corresponding to ISO material codes M and S. Secondary workpiece material compatibility covers steel, non-ferrous metals, and hard materials (ISO codes P, N, H). Applicable material grades are M10, S10, P10, N10, and H20. The MM4 chip breaker geometry supports turning, facing, and boring operations across these material groups. It is suited to high-value aerospace, medical, and industrial component machining where tool life and surface finish in difficult-to-machine alloys are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePVD-coated TiAlN, Al2O3, and ZrN multilayer coating under WSM01 proprietary grade for extended tool life in hard-to-machine alloys\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape (T) with 60-degree included angle and positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003e0.4 mm corner radius with honed cutting edge style for consistent surface finish\u003c\/li\u003e\n\u003cli\u003eThree cutting edges per insert maximizing cost-per-edge value\u003c\/li\u003e\n\u003cli\u003eMM4 chip breaker geometry supports turning, facing, and boring in a single insert\u003c\/li\u003e\n\u003cli\u003eScrew-holding method with 2.80 mm hole diameter for secure, repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eConforms to ANSI and ISO standards.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to seat the clamping screw to toolholder manufacturer specifications  -  do not overtighten, as carbide inserts are brittle and can crack under excess clamp force. Verify insert seating and edge orientation before resuming cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPGT110204-MM4 WSM01\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (T), 60-degree included angle\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, Al2O3, ZrN  -  PVD process, WSM01 grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MM4\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, 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.4 mm (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 6.35 mm (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.00 mm (0.4330 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 2.38 mm (0.0938 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 2.80 mm (0.1100 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 11.00 mm (0.4330 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium (M, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel, Non-Ferrous Metal, Hard Material (P, N, H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grades\u003c\/strong\u003e: M10, S10, P10, N10, H20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\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\u003eWeight\u003c\/strong\u003e: 0.007 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: WALTER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7021267\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":52056556798258,"sku":"7021267","price":384.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aaa5902804195a7161249be8c7087b4b.jpg?v=1790038290","url":"https:\/\/voomisupply.com\/products\/walter-7021267-tpgt110204-mm4-wsm01-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
