Allied 7C217P-0022CI Spade Drill Insert 11/16 in Carbide 140 Deg

Product Description

The ALLIED MACHINE AND ENGINEERING 7C217P-0022CI is a spade drill insert designed for high-performance drilling in cast iron and similar hard materials. Part of the GEN3SYS XT series, this insert measures 11/16 inches in diameter with a 140-degree point angle for aggressive material penetration and reduced thrust. The insert is manufactured from C2 (K20) grade carbide and features an AM300 PVD coating for extended tool life. At 0.005 pounds, it is a compact, precision-ground cutting tool intended for use with compatible spade drill bodies in metal fabrication and machining operations. Licensed machinists and tool-and-die professionals are the primary installers.

This insert is suited for drilling operations in cast iron workpieces across industrial machining environments. The GEN3SYS XT series is engineered for applications where consistent hole quality, dimensional accuracy, and insert-to-body repeatability are required. Seat Size 17 designates the compatible body seat interface. The fractional inch measurement system makes it straightforward to spec into inch-based machining programs. It is used in both production and job-shop settings where carbide spade tooling is the preferred approach over twist drills for its rigidity and chip control characteristics.

Key Features

• 11/16 inches diameter with Seat Size 17 body interface
• 140-degree point angle for reduced entry thrust and accurate hole starts
• C2 (K20) grade carbide substrate optimized for cast iron (K-material) applications
• AM300 PVD coating for improved wear resistance and longer insert life
• Part of the GEN3SYS XT series for consistent insert-to-body repeatability
• Fractional inch system for straightforward integration into inch-based tooling programs

Compatibility

Designed for use with GEN3SYS XT series spade drill bodies accepting a Seat Size 17 insert. Primary workpiece material classification is K (cast iron). Verify body compatibility using the Allied Machine and Engineering GEN3SYS XT tooling system specifications before installation.

Installation Notes

Insert installation should be performed by a qualified machinist following the drill body manufacturer's torque and seating procedures as specified in the GEN3SYS XT system documentation. Always ensure the drill body seat is clean and free of chips or debris before seating the insert. Confirm spindle speed and feed rate parameters are set per the recommended values for cast iron and carbide tooling before engaging the workpiece. Never force or hammer an insert into the seat, as this can damage the carbide substrate or the body pocket.
