Product Description

The ALLIED MACHINE AND ENGINEERING 7C217P-17.5CI is a solid carbide spade drill insert designed for high-performance drilling in cast iron and similar K-category workpiece materials. It features a 140-degree point angle optimized for controlled entry and clean hole geometry in hard, abrasive materials. The insert carries an AM300 PVD coating applied over a C2 (K20) carbide grade substrate, providing wear resistance and extended tool life in production drilling environments. This insert is part of the GEN3SYS XT series and is sized to Seat Size 17, making it a precision-ground replacement or spare for compatible spade drill holders. Machinists and toolroom professionals install this insert in CNC machining centers and drill presses.

This insert is suited for drilling operations in cast iron components across general machining, automotive, and industrial manufacturing applications. The 17.5 mm diameter and Seat Size 17 designation match it to GEN3SYS XT series spade drill holders. It is intended for use where a PVD-coated, solid carbide insert is specified for K-category workpiece materials such as gray cast iron, nodular iron, and similar materials. The single-insert packaging supports toolroom restocking or direct line replacement without overstocking.
