Allied Machine 7C218P-0024 Spade Drill Insert 3/4in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 7C218P-0024 is a solid carbide spade drill insert designed for high-performance through-tool or modular spade drilling operations. Part of the GEN3SYS XT series, it features a 3/4 inch cutting diameter, a 140-degree point angle, and an AM300 PVD coating that improves wear resistance and tool life in demanding applications. The C2 (K20) carbide grade supports aggressive feed rates in a range of workpiece materials. Seat Size 18 indexes directly into compatible GEN3SYS XT spade drill holders. This insert is used by machinists and toolroom professionals in production drilling applications where close-tolerance hole quality and extended tool life are required.

The 7C218P-0024 is suited for drilling stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium — covering ISO material groups M, K, N, and S. The GEN3SYS XT platform is commonly deployed in CNC machining centers, lathes with live tooling, and dedicated drilling machines in job shop and production manufacturing environments. The AM300 coating helps reduce built-up edge when cutting non-ferrous materials and provides oxidation resistance when machining super-alloys and titanium. Typical applications include hole-making in aerospace components, hydraulic manifolds, pump housings, and general industrial parts.

Key Features

• 3/4 inch cutting diameter with Seat Size 18 for direct indexing into GEN3SYS XT holders
• 140-degree point angle reduces thrust force and improves chip formation at entry
• Solid carbide construction, grade C2 (K20), for rigidity and edge integrity at high feeds
• AM300 PVD coating extends tool life across stainless steel, cast iron, non-ferrous, and super-alloy workpieces
• Covers ISO material groups M, K, N, and S in a single insert geometry
• Part of the GEN3SYS XT series for consistent insert-to-holder repeatability

Compatibility

Designed for use with GEN3SYS XT series spade drill holders accepting Seat Size 18 inserts. Suitable for primary workpiece materials including stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium (ISO groups M, K, N, S).

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the tool holder is secured before seating or removing the insert. Use the correct torx or insert-seating key specified for the GEN3SYS XT holder to achieve proper clamping torque — refer to the holder manufacturer documentation for fastener specifications. Inspect the insert seat for chips or debris before indexing; contamination in the seat will affect hole position and insert seating integrity.
