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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21 mm cutting diameter with a 140-degree point angle for aggressive chip formation and self-centering entry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction in C1 (K35) grade for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAM300 PVD coating classification provides thermal and abrasion resistance, extending tool life in steel and hard material applications\u003c\/li\u003e\n  \u003cli\u003eGEN3SYS XT series platform designed for high-penetration-rate drilling in production environments\u003c\/li\u003e\n  \u003cli\u003eSeat Size 20 interface for compatibility with corresponding spade drill holder bodies\u003c\/li\u003e\n  \u003cli\u003eHeight of 0.49 inches for precise seating depth in compatible holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Seat Size 20 spade drill holder bodies in the GEN3SYS XT series.
