Sumitomo 1AHD072 Indexable Drill Insert WDXT15H ACK300

Product Description

The SUMITOMO 1AHD072 is a solid carbide indexable drill insert in the WDXT style, designed for use in indexable drill bodies requiring a parallelogram-shaped insert. It carries the ACK300 manufacturer grade and features a PVD-applied TiAlN and AlCrN dual coating for extended tool life across a wide range of workpiece materials. The inscribed circle measures 15 mm (0.5906 inches), the thickness is 0.2362 inches, and the corner radius is 0.0472 inches. This insert is installed by machinists and tool-room technicians in production drilling operations where repeatable hole quality and insert indexability are required.

The 1AHD072 is suited for universal application across multiple workpiece material categories, including cast iron (K), stainless and heat-resistant alloys (M), non-ferrous materials (N), steel (P), and superalloys (S). It is commonly used in CNC machining centers and drill press setups where indexable tooling systems replace solid drill assemblies to reduce tooling cost per hole. The H chipbreaker geometry supports chip control across these varied materials.

Key Features

• ACK300 grade carbide with PVD-applied TiAlN and AlCrN coating for wear resistance and thermal stability
• WDXT insert style in a parallelogram shape for secure seating in compatible drill bodies
• 15 mm inscribed circle (0.5906 inches) with insert size code 15
• H chipbreaker for effective chip evacuation across universal workpiece materials
• 0.0472-inch corner radius reduces edge stress at drill entry and exit
• Compatible with material codes K, M, N, P, and S covering a broad range of production applications

Compatibility

Designed for use in indexable drill bodies that accept WDXT-style parallelogram inserts with a 15 mm inscribed circle. Verify insert style, size code, and corner radius against the drill body specification before ordering.

Installation Notes

Insert replacement should be performed by a qualified machinist with the spindle locked and machine power isolated per shop safety procedures. Use the correct torque driver or insert clamp tool specified by the drill body manufacturer — do not overtighten the clamping screw, as this can fracture the carbide. Inspect the insert pocket and clamping mechanism for wear or debris before seating a new insert. Follow the drill body manufacturer guidelines for insert orientation and indexing sequence.
