Allied Machine 4C1ZP-.453 Spade Drill Insert 29/64 in

Product Description

The ALLIED MACHINE AND ENGINEERING 4C1ZP-.453 is a solid carbide spade drill insert designed for high-performance hole-making in ferrous and hard materials. Part of the GEN2 T-A series, this insert features a 132-degree point angle and an AM300 PVD coating that extends tool life in demanding cutting conditions. It is sized at 29/64 inches in diameter with a Seat Size Z designation, making it a direct-fit replacement for compatible T-A spade drill holders. Machinists and tooling specialists in metalworking, fabrication, and machining operations are the primary users of this insert.

This insert is suited for drilling steel and hard materials in both production and maintenance machining environments. The GEN2 T-A series is a widely used platform in CNC machining centers, drill presses, and manual lathes where spade-style drilling is preferred for deep-hole or large-diameter applications. The AM300 coating provides improved wear resistance when cutting ferrous workpieces classified under material grades P and H. This insert ships individually and is intended for use in a compatible T-A series spade drill holder body.
