Allied Machine 7C218P-0023 Spade Drill Insert 23/32 in

Product Description

The ALLIED MACHINE AND ENGINEERING 7C218P-0023 is a carbide spade drill insert designed for high-performance hole-making in demanding machining environments. Part of the GEN3SYS XT series, this insert measures 23/32 inches in diameter with a 140-degree point angle optimized for penetrating hard and abrasive workpiece materials. The AM300 PVD coating provides thermal resistance and extended edge life. At 0.005 pounds, the insert is lightweight but engineered for rigidity in seat size 18 spade drill holders. Machining professionals and tooling technicians install this insert as a direct replacement or fresh setup in production drilling operations requiring tight hole tolerances and consistent tool life.

This insert is suited for drilling stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its GEN3SYS XT series geometry and AM300 coating address the specific challenges of these material groups, including work hardening in stainless and superalloys, abrasive wear from cast iron, and galling from non-ferrous and titanium alloys. It is appropriate for CNC machining centers and drill presses operating in both job shop and high-volume production settings where consistent hole quality across difficult materials is required.

Key Features

• 23/32 inch diameter with 140-degree point angle for aggressive chip formation and accurate entry
• Carbide substrate rated at manufacturer grade C2 (K20) for hardness and wear resistance
• AM300 PVD coating provides oxidation resistance and reduces built-up edge on difficult materials
• GEN3SYS XT series geometry engineered for stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• Fractional inch seat size 18 for direct drop-in fit with compatible spade drill holders
• Single insert per package with a minimum order quantity of 1 for flexible tooling procurement

Compatibility

Designed for use with seat size 18 spade drill holders in the GEN3SYS XT system. Compatible with primary workpiece material codes M (stainless steel), K (cast iron), N (non-ferrous metal), and S (superalloys and titanium).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered down and locked out per applicable safety procedures. Ensure the seat and clamping surfaces of the holder are clean and free of chips or debris before seating the insert. Use the manufacturer-recommended torque driver for the clamping screw to avoid seat damage. Inspect insert seating and holder condition at each tool change interval.
