Allied Machine 7C122P-.890 Spade Drill Insert 57/64 in

Product Description

The ALLIED MACHINE AND ENGINEERING 7C122P-.890 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. It features a 140-degree point angle and an AM300 PVD coating applied over a C1 (K35) carbide grade substrate. The insert measures 57/64 inches in diameter and fits a Seat Size 22 holder body. Part of the GEN3SYS XT series, this insert is engineered for precision hole-making in demanding production environments where tool life and dimensional accuracy are critical. Machinists and tooling specialists working in metalworking and manufacturing operations are the primary users.

This insert is suited for drilling operations in steel and hard workpiece materials in both light and heavy industrial settings. The GEN3SYS XT series is designed for modular spade drill systems where inserts are replaced independently from the holder body, reducing tooling cost per hole. The AM300 coating provides enhanced wear resistance and thermal stability during high-feed drilling applications.

Key Features

• Solid carbide construction in Manufacturer Grade C1 (K35) for rigidity and wear resistance
• AM300 PVD coating classification for improved tool life in steel and hard materials
• 140-degree point angle for reduced thrust force and accurate hole entry
• Seat Size 22 compatibility with GEN3SYS XT modular spade drill holder bodies
• 57/64 inch diameter for precise bore sizing without secondary operations
• Designed for primary workpiece materials coded P (steel) and H (hard materials)

Compatibility

Designed for use with GEN3SYS XT series Seat Size 22 spade drill holder bodies. Specific holder compatibility should be verified against Allied Machine and Engineering tooling system documentation before ordering.

Installation Notes

Insert installation and removal should be performed by a qualified machinist or tooling technician using the appropriate torque wrench and insert seat hardware specified by the holder manufacturer. Power down and lock out the machine spindle before changing inserts. Inspect the insert seat for debris or damage prior to seating the insert, as contamination in the seat can cause premature insert failure or dimensional runout. Follow the holder manufacturer's clamping procedure to ensure proper seating without over-torquing.
