Sumitomo 1AHD020 Indexable Drill Insert WDXT06G ACK300

Product Description

The SUMITOMO 1AHD020 is a solid carbide indexable drill insert designed for use in indexable-style drilling tools on CNC machining centers and drill press setups. Featuring the WDXT06G insert style with an ACK300 manufacturer grade and a PVD coating process, this insert delivers consistent cutting performance across a broad range of workpiece materials. The inscribed circle measures 6.00 mm (0.2362 inches), the thickness is 0.1181 inches, and the corner radius is 0.0236 inches. The parallelogram shape and right-hand cutting direction make this insert a direct fit for compatible WDXT-style drill bodies. Machinists and tooling specialists working in job shops, production machining, or maintenance environments will find this a reliable replacement insert.

This insert is rated for universal primary workpiece material compatibility, covering material codes K, M, N, P, and S. That range spans cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys. It suits a wide variety of drilling applications in both light and moderate production environments. The G chipbreaker geometry supports chip control across these material groups. The insert ships individually but carries a minimum order quantity of 10 units, making it appropriate for tooling stock replenishment or scheduled insert changeout programs.

Compatibility

Designed as an OEM-style replacement insert for WDXT-style indexable drill bodies accepting a size 06 insert with a 6.00 mm inscribed circle. Confirm drill body manufacturer specifications before installation to ensure proper seating and torque requirements.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine locked out per facility lockout/tagout procedures. Use the appropriate insert clamp screw torque driver specified by the drill body manufacturer. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Do not force the insert into the pocket, as improper seating can cause insert fracture or tool body damage during operation.
