Sumitomo 1AHD025 Indexable Drill Insert WDXT09H ACK300

Product Description

The SUMITOMO 1AHD025 is a solid carbide indexable drill insert in the WDXT09H style, finished with an ACK300 PVD coating for extended wear resistance and thermal stability. This parallelogram-shaped insert features a 9 mm (0.3543 inch) inscribed circle, a 0.1575-inch thickness, and a 0.0315-inch corner radius. The H chipbreaker geometry is engineered for efficient chip evacuation in through-hole and spot-drilling applications. Licensed machinists and toolroom technicians install this insert into compatible indexable drill bodies as a direct replacement tip, minimizing downtime and maintaining consistent bore quality.

This insert is suited for a wide range of workpiece materials, carrying a universal primary workpiece material rating that spans ISO material codes K, M, N, P, and S. That coverage includes cast iron, stainless steel, non-ferrous alloys, carbon and alloy steels, and heat-resistant super alloys. Typical applications include production drilling on CNC machining centers and lathes in both job-shop and high-volume manufacturing environments. Right-hand cutting direction is standard.

Key Features

• ACK300 grade solid carbide substrate with PVD coating for wear and heat resistance
• WDXT insert style in parallelogram shape with H chipbreaker geometry
• 9 mm (0.3543 inch) inscribed circle for precise seating in compatible drill bodies
• 0.0315-inch corner radius reduces edge chipping on entry and exit
• Universal workpiece material compatibility across ISO codes K, M, N, P, and S
• Right-hand cutting direction; sold individually (minimum order quantity of 10 units)

Compatibility

Designed as a direct replacement indexable drill insert for WDXT-style insert seats with a 9 mm inscribed circle and 09 insert size designation. Confirm seat geometry and clamping style in the drill body before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before removing or seating any indexable insert. Use the appropriate torx or hex key at the manufacturer-specified torque range for the drill body to ensure the insert is fully seated without cracking the carbide. Inspect the insert pocket for chips or debris before installing a new insert, and verify cutting direction matches the spindle rotation of the application.
