Allied 7C218P-18CI Spade Drill Insert 18mm Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 7C218P-18CI is a solid carbide spade drill insert designed for high-performance drilling in cast iron and similar hard workpiece materials. Part of the GEN3SYS XT series, this insert features an 18 mm cutting diameter and a 140-degree point angle optimized for clean entry and chip control. The AM300 PVD coating improves wear resistance and extends tool life in demanding production environments. At 0.01 pounds, it is a compact, precision-ground insert intended for use with compatible spade drill bodies. Machinists, tool-and-die professionals, and CNC operators in metalworking and manufacturing applications are the primary installers and users.

This insert is suited for drilling operations in cast iron (material grade K, C2/K20) in both production machining and job-shop environments. It fits seat size 18 spade drill holders in the GEN3SYS XT series platform. Typical applications include through-hole and blind-hole drilling on vertical machining centers, horizontal boring mills, and CNC lathes where consistent hole quality and tool life are critical.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle locked. Use the correct torque wrench and manufacturer-specified insert screws when seating the insert into the drill body — do not substitute hardware. Inspect the seat and clamping pocket for chips or debris before mounting. Follow your facility's lockout/tagout procedures before any tooling change.
