Sumitomo 1AHD070 Indexable Drill Insert WDXT15G ACK300

Product Description

The SUMITOMO 1AHD070 is a solid carbide indexable drill insert in the WDXT style with a manufacturer grade of ACK300. It is designed for use in indexable drill systems where reliable, repeatable cutting performance is required. The insert features a parallelogram shape with a 15 mm (0.5906 inch) inscribed circle, a thickness of 0.2362 inches, and a corner radius of 0.0472 inches. The ACK300 grade is applied via a PVD coating process, producing a coated finish suited for a wide range of workpiece materials. Installation is handled by machinists and tooling specialists in production or job shop environments.

This insert is rated for universal primary workpiece material compatibility, covering material codes K, M, N, P, and S. That broad coverage makes it applicable to cast iron, steel, non-ferrous metals, heat-resistant superalloys, and stainless steel families. It is intended for right-hand cutting direction and carries a G chipbreaker designation. Typical applications include through-hole and blind-hole drilling operations on machining centers and CNC lathes where indexable drill tooling bodies are already in use.

Key Features

• WDXT insert style in a parallelogram shape for secure seating in compatible tooling bodies
• ACK300 PVD-coated solid carbide grade for wear resistance across universal workpiece materials
• 15 mm inscribed circle (0.5906 inches) with insert size code 15
• Corner radius of 0.0472 inches for controlled edge geometry
• Right-hand cutting direction
• G chipbreaker for effective chip evacuation across varied feed and depth conditions

Compatibility

Designed as an OEM-style replacement or direct-use insert for indexable drill tooling bodies that accept WDXT-style inserts with a 15 mm inscribed circle and parallelogram geometry.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine spindle fully stopped and the tooling body secured. Use the appropriate torx or hex key specified by the tooling body manufacturer to seat the insert clamp to proper engagement. Inspect the insert pocket and clamp for wear or damage before seating a new insert. Never force an insert into a pocket that does not accept it freely, as improper seating leads to premature edge failure or tooling body damage.
