Seco Tools is a world-leading precision cutting tools manufacturer supplying indexable turning inserts, milling inserts, turning toolholders, milling cutters, and solid carbide drills for CNC turning, milling, boring, and drilling operations in steel, stainless steel, cast iron, aluminium, titanium, and high-temperature alloys in engineering workshops and manufacturing environments across Australia. Seco indexable milling inserts — in carbide grades, chipbreaker geometries, and insert styles covering square shoulder milling, face milling, disc milling, parting, and profile milling — provide the cutting edge for Seco milling cutter bodies in machining steel, stainless steel, cast iron, aluminium, titanium, and non-ferrous materials. Where this product is used Seco milling insert products are used in CNC and manual machining operations in engineering workshops, tool rooms, and production manufacturing environments where Seco precision cutting tools are specified for metalcutting operations. Square shoulder, face mill, disc mill, and profile milling inserts providing the indexable cutting edge for Seco milling cutter bodies across a range of milling operations. Inserts in multiple carbide grades covering general steel, stainless steel, cast iron, aluminium, and titanium milling applications with chipbreakers optimised for face and shoulder milling conditions. Neutral and handed insert configurations (N, L, R) matched to the milling cutter body specification — confirm the insert style and chipbreaker suits the cutter body before ordering. Key specifications Specification Detail Designation F40M Selecting the right option Select Seco milling inserts by the cutter body designation — the insert style, size, and chipbreaker must match the cutter body specification exactly. Neutral (N), left (L), and right (R) handed versions are not interchangeable — confirm the correct version for the cutter body before ordering. Grade selection depends on workpiece material and cutting conditions — contact AIMS for Seco milling insert grade selection guidance or for quantities not listed.
