Built to insert style P284 and graded WK40, this square-shaped insert features a 96-degree included angle and four cutting edges, maximizing the number of usable edges per insert before replacement. At 0.3800 inches in both width and length, it conforms to ANSI and ISO standards and carries ISO code P2840S-3N-E67 WK40. Licensed machinists, tool-and-die technicians, and CNC operators working in high-mix production environments are the primary installers and end users.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for primary application in non-ferrous metals, superalloys, and titanium, making it well-suited for aerospace, medical device, and precision-machined-component manufacturing. The WK40 carbide grade is selected for its balance of wear resistance and toughness in these challenging workpiece categories. It is sized to insert size code 28 and fits drilling tool bodies designed to accept P284-style square inserts. Both ANSI and ISO conformance broadens its compatibility across globally sourced tooling systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in manufacturer grade WK40 for wear resistance in superalloy and titanium cutting\u003c\/li\u003e\n  \u003cli\u003eSquare shape with 96-degree included angle and four cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eWidth and length of 0.3800 inches for precision fit in size code 28 tool bodies\u003c\/li\u003e\n  \u003cli\u003ePrimary workpiece material codes N and S cover non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eDual ANSI and ISO compliance for broad tooling system compatibility\u003c\/li\u003e\n  \u003cli\u003eISO code P2840S-3N-E67 WK40 for exact cross-reference and procurement matching\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for indexable insert drill bodies that accept P284-style square inserts at insert size code 28, conforming to ANSI and ISO standards.

Ensure the machine spindle is fully stopped and the tool is secured in a vise or tool holder before seating or removing inserts. Use the correct torx or hex key at the manufacturer-specified procedure for the tool body clamp screw  -  do not overtighten, as carbide inserts are brittle and can crack under excessive clamping force. Inspect the insert pocket seat 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: P284\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: WK40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 96 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3800 inches (9.52 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.3800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: P2840S-3N-E67 WK40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal, Superalloy, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: N, S\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: 0.03 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: 7487733\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":52085404762418,"sku":"7487733","price":235.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0e3733def81fa7a3b1cebbd078db85f.jpg?v=1790058946","url":"https:\/\/voomisupply.com\/products\/walter-7487733-indexable-drill-insert-square-wk40-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
