Sumitomo 1AHB018 Indexable Drill Insert WDXT07L ACP300

Product Description

The SUMITOMO 1AHB018 is a solid carbide indexable drill insert designed for use in indexable drilling applications across a wide range of workpiece materials. Carrying the WDXT07L insert style designation, this insert features a 7 mm (0.2756 inches) inscribed circle, a thickness of 0.1378 inches, and a corner radius of 0.0236 inches. The parallelogram shape and WDXT-style geometry are engineered for the specific seat geometry of compatible indexable drill bodies. The ACP300 grade features a PVD coating process, delivering wear resistance and edge integrity suited for universal workpiece material categories. Right-hand cutting direction is standard. Installation and replacement are performed by machinists and tool crib technicians in production and job-shop environments.

This insert is rated for universal primary workpiece material compatibility, covering material codes K, M, N, P, and S. These codes correspond to cast iron, stainless steel, non-ferrous materials, steel, and heat-resistant superalloys respectively. The L chipbreaker geometry is suited for applications requiring controlled chip formation during drilling operations. Typical use scenarios include CNC machining centers and drill press setups where indexable drill tooling requires periodic insert rotation or replacement to maintain cutting performance and dimensional accuracy.

Compatibility

Designed for use in WDXT-style indexable drill bodies requiring the WDXT07L insert geometry. Confirm insert style, inscribed circle size, and seat configuration against the drill body specification before ordering. Specific compatible drill body model numbers were not provided in available product data.

Installation Notes

Insert replacement should be performed with the machine powered down and the spindle locked. Use the appropriate torx or hex key as specified by the drill body manufacturer when seating or removing the clamping screw. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert. Ensure the insert seats fully and flush in the pocket before returning the tool to service.
