Allied Machine 7C220P-0026 Spade Drill Insert 13/16 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 7C220P-0026 is a solid carbide spade drill insert designed for high-performance drilling in demanding industrial applications. Built to the GEN3SYS XT series standard, this insert features a 13/16 inch diameter, a Seat Size 20 designation, and a 140-degree point angle. The AM300 PVD coating provides enhanced wear resistance and thermal stability, extending tool life across aggressive cutting conditions. At 0.029 pounds, the insert is precision-machined to tight tolerances and seats securely in compatible GEN3SYS XT spade drill holders. Installation and use are typical for machining operations in production and job-shop environments.

This insert is suited for drilling stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium — material codes M, K, N, and S. The C2 (K20) carbide grade makes it appropriate for both interrupted and continuous cutting in these material families. Typical applications include production drilling on CNC machining centers, lathes, and drill presses where consistent hole quality and insert indexability are required. The GEN3SYS XT platform is engineered for through-coolant capable holders, making this insert a practical choice for deep-hole and high-feed drilling cycles.

Key Features

• Solid carbide construction in manufacturer grade C2 (K20) for hardness and thermal resistance
• AM300 PVD coating for improved wear life on difficult-to-machine materials
• 140-degree point angle suited for flat-bottom entry and reduced thrust force
• 13/16 inch diameter with Seat Size 20 for direct drop-in fit to GEN3SYS XT holders
• Compatible workpiece materials include stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium
• Lightweight at 0.029 pounds with compact geometry: 1.75 inches length, 1.63 inches width, 0.75 inches height

Compatibility

Designed for use with GEN3SYS XT series spade drill holders accepting Seat Size 20 inserts at 13/16 inch diameter. Verify holder seat size and insert diameter before installation.

Installation Notes

This insert is installed by a machinist or tooling technician into a compatible GEN3SYS XT spade drill holder. Always power down and lock out the machine spindle before seating or removing any drill insert. Use the correct insert screw and torque driver specified by the holder manufacturer — do not overtighten or substitute fasteners. Inspect the holder seat for chips or debris before seating the insert to ensure proper contact and runout accuracy.
