Allied 7C218P-18AS Spade Drill Insert 18mm 140pt GEN3SYS Xt

Product Description

The ALLIED MACHINE AND ENGINEERING 7C218P-18AS is an 18 mm diameter solid carbide spade drill insert designed for high-performance hole-making in demanding materials. Built to GEN3SYS XT series standards, this insert features a 140-degree point angle that promotes accurate entry and efficient chip evacuation. The AM300 PVD coating provides thermal resistance and wear protection, extending tool life in production environments. Seat Size 18 ensures precise seating in compatible spade drill bodies. This insert is installed by machinists and toolroom technicians working on CNC machining centers, manual lathes, and drill presses where consistent bore quality is required.

This insert is engineered primarily for stainless steel applications, classified under workpiece material code M, which covers austenitic and ferritic stainless grades. The GEN3SYS XT platform is suited to both light production and high-volume drilling operations in metalworking facilities, job shops, and aerospace or medical component manufacturing environments. The solid carbide construction with C2 (K20) manufacturer grade delivers the hardness and edge retention needed to maintain dimensional consistency across repeated drilling cycles.
