Sumitomo 1AHD065 Indexable Drill Insert WDXT04H ACK300

Product Description

The SUMITOMO 1AHD065 is a solid carbide indexable drill insert designed for use in indexable-style drilling tools. Manufactured to the WDXT04H insert specification with Sumitomo ACK300 grade, this insert features a TiAlN and AlCrN dual-coating applied via PVD process, delivering strong wear resistance and thermal stability across a wide range of workpiece materials. With a 4 mm (0.1575 inch) inscribed circle and a 0.0157-inch corner radius, this parallelogram-shaped insert is suited for precision boring and drilling operations. It is typically installed by machinists and tooling technicians working in CNC or manual machining environments.

This insert is rated for universal workpiece material compatibility, covering material codes K, M, N, P, and S, which span cast iron, stainless steel, non-ferrous materials, steel, and heat-resistant superalloys. The WDXT04H form factor with the H chipbreaker geometry makes it appropriate for through-hole and blind-hole drilling applications across both light and moderate cutting conditions. It is sold individually with a minimum order quantity of one.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the drill body is fully de-energized and secured before changing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified seating procedure and verify insert seating is flush and secure before resuming cutting operations. Do not exceed the cutting parameters specified by the toolholder manufacturer for this insert size and grade.
