Manufactured from solid carbide and finished with a PVD-applied TiAlN and TiN coating, this insert delivers thermal resistance and edge durability in demanding drilling operations. It carries a manufacturer grade of T400D and an insert size code of 08, with a chipbreaker designation of 86. The 80-degree trigon shape provides a stable cutting geometry, while the 7-degree relief angle reduces cutting forces at the tool tip. A corner radius of 1.2 mm helps distribute load and resist chipping during entry and exit. Licensed HVAC techs, machinists, and toolroom professionals handling multi-material drilling applications will find this insert a reliable consumable for production and maintenance work.\u003c\/p\u003e\u003cp\u003eThis insert is rated for universal primary workpiece material compatibility, covering material groups H, K, M, N, P, and S. That range includes cast iron, non-ferrous alloys, steel, stainless steel, heat-resistant superalloys, and general-purpose steels. It is suited for both light-production and high-volume drilling scenarios in CNC machining centers and dedicated drill presses where indexable tooling is standard. The inscribed circle measures 12.70 mm and the overall cutting length is 8.14 mm (0.32 inches), making it a compact insert appropriate for moderate-diameter hole drilling applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWCMX insert style with 80-degree trigon geometry for stable, low-force drilling\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiAlN and TiN dual coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e1.2 mm corner radius reduces chipping risk during entry and breakthrough\u003c\/li\u003e\n\u003cli\u003e7-degree relief angle minimizes rubbing and cutting-edge heat buildup\u003c\/li\u003e\n\u003cli\u003eUniversal material grade compatibility covering H, K, M, N, P, and S workpiece groups\u003c\/li\u003e\n\u003cli\u003eChipbreaker designation 86 optimized for chip control across varied feed conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement-style WCMX0886 indexable drill insert compatible with indexable insert drill bodies that accept WCMX-style inserts in size code 08.

Ensure the machine spindle is fully stopped and locked out before changing inserts. Inspect the insert pocket for chips, burrs, or seat damage before seating the new insert. Use only the drive key or torx driver specified by the tool body manufacturer to avoid stripping the clamp screw.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WCMX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Trigon, 80 degrees included angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: T400D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.70 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Length\u003c\/strong\u003e: 8.14 mm (0.32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: 86\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 08\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 080412\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 02506646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558061015346,"sku":"02506646","price":305.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23e8181be60018c28b0562e4e1d375fe.jpg?v=1786402248","url":"https:\/\/voomisupply.com\/products\/seco-02506646-wcmx0886-t400d-indexable-drill-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
