Allied Machine 7C120P-21 Spade Drill Insert 21mm Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 7C120P-21 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. It features a 21 mm cutting diameter, a 140-degree point angle, and an AM300 PVD coating applied to a C1 (K35) carbide grade substrate. This insert seats into Seat Size 20 compatible spade drill holders and is part of the GEN3SYS XT series, a platform engineered for improved penetration rates and tool life in demanding production environments. Machinists, tooling engineers, and CNC operators in manufacturing and job shop settings are the primary installers and users of this insert.

The 7C120P-21 is suited for drilling operations in steel and hard workpiece materials across both light and heavy production applications. The GEN3SYS XT series is designed for through-coolant compatible holders and is commonly used in CNC machining centers and drill presses where consistent hole geometry and tool life are priorities. The AM300 coating provides enhanced wear resistance and thermal stability, making this insert appropriate for interrupted cuts and high-feed applications in ferrous materials.

Key Features

• 21 mm cutting diameter with a 140-degree point angle for aggressive chip formation and self-centering entry
• Solid carbide construction in C1 (K35) grade for rigidity and wear resistance in hard and abrasive materials
• AM300 PVD coating classification provides thermal and abrasion resistance, extending tool life in steel and hard material applications
• GEN3SYS XT series platform designed for high-penetration-rate drilling in production environments
• Seat Size 20 interface for compatibility with corresponding spade drill holder bodies
• Height of 0.49 inches for precise seating depth in compatible holders

Compatibility

Designed for use with Seat Size 20 spade drill holder bodies in the GEN3SYS XT series. Primary workpiece material compatibility includes steel and hard materials as specified by material codes P and H.

Installation Notes

This insert is installed and serviced by machinists or tooling technicians in CNC or manual drilling operations. Ensure the spindle is fully stopped and the machine is locked out before changing inserts. Use the manufacturer-specified torque driver and insert screw for the GEN3SYS XT holder to avoid seat damage or insert movement during cutting. Inspect the holder seat for chips or debris before seating the insert to maintain accurate positioning and tool life.
