Allied 7C120P-20.5 Spade Drill Insert 20.5mm Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 7C120P-20.5 is a solid carbide spade drill insert engineered for high-performance drilling in demanding metal-cutting applications. Part of the GEN3SYS XT series, this insert features a 20.5 mm cutting diameter, a 140-degree point angle, and an AM300 PVD coating for extended tool life and heat resistance. The C1 (K35) carbide grade provides the hardness and wear resistance required for steel and hard material workpieces. It is installed and serviced by machinists and tooling specialists in production, job shop, and maintenance environments.

This insert is designed for use in GEN3SYS XT spade drill holders with a Seat Size 20 seat. Typical applications include through-hole and blind-hole drilling in steel and hard materials on CNC machining centers, lathes, and drill presses. The AM300 PVD coating makes it well suited for dry or minimal-lubrication cutting conditions where heat buildup is a concern. It is commonly used in automotive, aerospace, and general metalworking production settings where consistent hole quality and insert longevity are priorities.

Key Features

• 20.5 mm cutting diameter with Seat Size 20 compatibility for GEN3SYS XT holders
• 140-degree point angle reduces thrust and improves chip formation in steel
• Solid carbide C1 (K35) grade delivers hardness and resistance to abrasive wear
• AM300 PVD coating classification extends edge life in steel and hard material cutting
• Compact insert geometry: 1.75 inches length, 1.63 inches width, 0.75 inches height
• Lightweight at 0.03 pounds for easy handling and fast changeover

Compatibility

Designed for use with GEN3SYS XT spade drill holders accepting a Seat Size 20 insert. Primary workpiece materials are steel and hard materials (material codes P and H).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill holder and machine spindle are fully de-energized and locked out before inserting or removing the spade drill insert. Use the correct insert screw torque procedure specified by the holder manufacturer and verify the insert is fully seated before resuming operation. Follow applicable shop safety standards and manufacturer tooling guidelines when setting cutting parameters.
