Sumitomo 1AHD067 Indexable Drill Insert WDXT12G ACK300

Product Description

The SUMITOMO 1AHD067 is a solid carbide indexable drill insert in WDXT12G style with ACK300 manufacturer grade, designed for use in indexable drill bodies requiring a parallelogram-shaped insert. The insert measures 0.4882 inches inscribed circle diameter and 0.1969 inches thick, with a 0.0472 inch corner radius. The ACK300 grade features a PVD-applied coating for improved wear resistance and thermal stability. Intended for right-hand cutting operations, this insert is suited for machining centers and CNC drilling applications where insert geometry and grade consistency are critical to hole quality and tool life.

The 1AHD067 carries a universal primary workpiece material designation, covering ISO material groups K, M, N, P, and S. This broad compatibility makes it suitable for drilling cast iron, steel, stainless, non-ferrous alloys, and high-temperature alloys in production environments. The G chipbreaker geometry supports chip control across this range of materials. Typical users include CNC machinists and tooling specialists in job shops, production facilities, and aerospace or general metalworking operations.

Installation Notes

Insert installation should be performed by a qualified machinist or tooling technician. Ensure the drill body and insert seat are clean and free of chips or debris before seating the insert. Use the correct torque driver or insert screw specified by the drill body manufacturer — do not overtighten. Inspect the insert seat and clamping screw for wear when replacing inserts to maintain proper cutting geometry and runout.
