Allied 7C222P-.921AS Spade Drill Insert 59/64 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 7C222P-.921AS is a solid carbide spade drill insert designed for high-performance drilling in demanding machining applications. With a 59/64 inch diameter and a 140-degree point angle, this insert delivers precise entry geometry and efficient chip evacuation. It carries a C2 (K20) carbide grade and an AM300 PVD coating, making it well-suited for cutting stainless steel and other difficult workpiece materials. This insert fits Seat Size 22 toolholders in the GEN3SYS XT series. Machinists and tooling technicians working in production or job-shop environments install this insert as a direct replacement or initial setup component.

This insert is intended for use in the GEN3SYS XT modular spade drill system. It is engineered primarily for stainless steel (Material Grade M) but the C2 carbide substrate and PVD coating provide durability across a range of ferrous and non-ferrous alloys in both CNC turning center and machining center setups. Typical applications include deep-hole drilling in precision components where tool life and hole quality are critical. Package quantity is 1 insert per unit.

Key Features

• 59/64 inch cutting diameter with 140-degree point angle for clean entry and reduced thrust
• Solid carbide construction with C2 (K20) material grade for wear resistance and edge stability
• AM300 PVD coating classification provides heat resistance and extended tool life in stainless steel
• Seat Size 22 interface for direct fit into compatible GEN3SYS XT spade drill bodies
• Optimized for stainless steel (Primary Workpiece Material Code M) applications

Compatibility

Designed for use with Seat Size 22 GEN3SYS XT series spade drill holders from ALLIED MACHINE AND ENGINEERING.

Installation Notes

Installation is performed by machinists or tooling technicians. Before replacing the insert, ensure the machine spindle is fully stopped and the tool is secured in a vise or holder. Seat surfaces on the drill body should be inspected and cleaned before seating the new insert to ensure proper contact and accurate runout. Follow the toolholder manufacturer's torque and clamping specifications for the Seat Size 22 interface.
