Allied Machine 7C122P-0028 Spade Drill Insert 7/8 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 7C122P-0028 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. It carries a 7/8-inch diameter cutting edge, a 140-degree point angle, and a Seat Size 22 designation for use in compatible spade drill holders. The insert is manufactured to Manufacturer Grade C1 (K35) and finished with an AM300 PVD coating, which reduces heat buildup and extends tool life in demanding cutting conditions. This is a precision cutting tool installed by machinists and tooling technicians in production and job-shop environments.

This insert is part of the GEN3SYS XT series, engineered for drilling into steel and hard materials in both CNC machining centers and manual drill press applications. The AM300 PVD coating is suited for ferrous workpiece materials including steels classified under material codes P and H. Typical installations involve high-feed, high-depth drilling operations where tool life and hole quality are critical. The insert seats into a matching Seat Size 22 spade drill body and is replaced as a consumable without removing the holder from the machine.

Key Features

• Solid carbide construction at Manufacturer Grade C1 (K35) for hardness and wear resistance
• AM300 PVD coating classification for extended tool life in steel and hard material applications
• 140-degree point angle suited for entry stability and chip control in ferrous materials
• 7/8-inch cutting diameter with Seat Size 22 for direct holder compatibility
• GEN3SYS XT series design for high-efficiency spade drilling operations
• Consumable insert format allows holder reuse and fast changeout at the machine

Compatibility

Designed for use in Seat Size 22 GEN3SYS XT spade drill holders. Primary workpiece materials are steel and hard materials, corresponding to material codes P and H.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Ensure the holder seat is clean and free of chips before installing the insert, as debris under the insert face can cause premature failure or poor hole geometry. Follow the toolholder manufacturer torque specifications for the insert clamping screw.
