Sumitomo 1AHB021 Indexable Drill Insert WDXT07G ACP300

Product Description

The SUMITOMO 1AHB021 is a solid carbide coated indexable drill insert designed for use in indexable drilling tools. Manufactured to the WDXT07G insert style with an ACP300 grade coating, this parallelogram-shaped insert delivers consistent cutting performance across a broad range of workpiece materials. It features a 0.2953-inch inscribed circle, a thickness of 0.1378 inches, and a 0.0236-inch corner radius. The G chipbreaker geometry supports chip control during drilling operations. This insert is installed by machinists and toolroom technicians working with indexable drill bodies in CNC and manual machining environments.

This insert is suited for universal application across multiple workpiece material categories, including cast iron, stainless and heat-resistant alloys, non-ferrous metals, and general steels, as indicated by material codes K, M, N, P, and S. Right-hand cutting direction makes it compatible with standard right-hand drill bodies. Typical applications include production drilling in metalworking shops, job shops, and manufacturing facilities where consistent hole quality and tool life are priorities.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key as specified by the drill body manufacturer to secure the insert clamp screw to the correct seating torque. Inspect the insert pocket for chips or debris before installing a new insert to ensure proper seating and prevent premature edge failure.
