Allied Machine 7C218P-0025 Spade Drill Insert 25/32 in

Product Description

The ALLIED MACHINE AND ENGINEERING 7C218P-0025 is a solid carbide spade drill insert designed for high-performance hole making in demanding machining applications. Built to seat size 18 and measuring 25/32 inches in diameter, this insert features a 140-degree point angle and a height of 0.46 inches. It carries an AM300 PVD coating, which is Allied's proprietary coating formulation developed for extended tool life in difficult-to-machine materials. The insert belongs to the GEN3SYS XT series and is manufactured to a C2 (K20) carbide grade. Machinists and tool-and-die professionals working in production drilling environments are the primary users of this insert.

This spade drill insert is engineered for use across a broad range of workpiece materials, including stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium. It is suited to both CNC machining centers and manual drilling setups where a compatible GEN3SYS XT spade drill holder of seat size 18 is in use. The AM300 coating and solid carbide substrate make it particularly well-suited for interrupted cuts and applications where heat generation is a concern, such as drilling austenitic stainless steels or titanium alloys at production volumes.

Key Features

• Solid carbide construction at C2 (K20) material grade for rigidity and wear resistance
• AM300 PVD coating for thermal protection and extended cutting life
• 140-degree point angle reduces thrust force and improves chip formation
• Compatible with GEN3SYS XT seat size 18 spade drill holders
• Rated for stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium workpieces
• Height of 0.46 inches for precise seating in the holder pocket

Compatibility

Designed for use with Allied Machine and Engineering GEN3SYS XT series spade drill holders configured for seat size 18. Suitable for workpiece materials classified under ISO material groups M (stainless steel), K (cast iron), N (non-ferrous metals), and S (super-alloys and titanium).

Installation Notes

Installation is performed by machinists or tool crib personnel responsible for tooling setup on CNC or manual drilling equipment. Before seating the insert, ensure the holder pocket is clean and free of chips or debris that could affect seating accuracy. Use the manufacturer-specified torque wrench and insert screw for the GEN3SYS XT holder to secure the insert — do not use substitute fasteners. Verify insert seating and runout before beginning a cutting cycle.
