Allied 7C222P-0028CI Spade Drill Insert 7/8 in Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 7C222P-0028CI is a solid carbide spade drill insert designed for high-performance drilling in cast iron workpieces. Carrying a 7/8 inch diameter and a 140-degree point angle, this insert is engineered for the GEN3SYS XT series spade drill system. The AM300 PVD coating provides wear resistance suited for the abrasive nature of cast iron machining. The C2 (K20) carbide grade targets cast iron, non-ferrous materials, and other K-category workpiece materials. Machinists, tool-and-die shops, and precision machining operations use this insert where consistent hole geometry and extended tool life in ferrous materials are required.

This insert fits Seat Size 22 holders in the ALLIED GEN3SYS XT spade drill platform. It is intended for production drilling in cast iron components, making it suitable for automotive, heavy equipment, and general industrial machining environments. The 7/8 inch cutting diameter and solid carbide construction support aggressive feed rates without sacrificing hole quality. Licensed machinists and CNC operators are the primary installers in shop environments operating vertical or horizontal machining centers and CNC lathes.

Installation Notes

Insert installation should be performed by a qualified machinist following the tool holder manufacturer's seating and clamping procedure. Ensure the holder and machine spindle are fully stopped and locked out before changing inserts. Use the correct torx or hex key as specified by the holder manufacturer for the clamping screw. Inspect the holder seat for chips or debris before seating the insert to prevent improper seating and premature failure.
