Sumitomo 1AHD069 Indexable Drill Insert WDXT12H ACK300

Product Description

The SUMITOMO 1AHD069 is a solid carbide indexable drill insert designed for use in indexable drilling operations across a wide range of workpiece materials. Carrying the WDXT insert style and ACK300 manufacturer grade, this insert features a TiAlN and AlCrN PVD coating for extended tool life and thermal resistance. The inscribed circle measures 12 mm (0.4724 inches), with a thickness of 0.1969 inches and a corner radius of 0.0472 inches. The parallelogram shape and right-hand orientation make it a precision fit for compatible indexable drill bodies. Licensed tool and die machinists, CNC operators, and production machinists are the typical end users.

This insert is suited for universal application across multiple workpiece material categories, including cast iron (K), stainless steel (M), non-ferrous materials (N), steel (P), and heat-resistant superalloys (S). It is appropriate for both production and job-shop drilling environments where consistent hole quality and insert interchangeability are required. The H chipbreaker geometry supports chip control across this broad material range, making the insert versatile for high-volume drilling programs.

Compatibility

Designed as a replacement or spare indexable drill insert for WDXT-style insert seats with a 12 mm inscribed circle and right-hand orientation. Confirm seat geometry, clamping style, and insert pocket dimensions against the drill body specifications before ordering.

Installation Notes

Installation of indexable inserts should be performed by qualified machinists or tooling technicians following the drill body manufacturer's seating and torque guidelines. Ensure the spindle is fully stopped and the machine is in a locked-out, de-energized state before changing inserts. Clean the insert pocket thoroughly before seating the new insert to prevent improper contact and premature edge failure. Do not exceed the recommended cutting parameters for the ACK300 grade as published by SUMITOMO for the target workpiece material.
