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

Product Description

The ALLIED MACHINE AND ENGINEERING 7C218P-0024CI is a solid carbide spade drill insert designed for high-performance drilling applications in metal cutting and machining operations. Measuring 3/4 inch in diameter with a 140-degree point angle, this insert mounts to compatible spade drill holders via a Seat Size 18 interface. The AM300 PVD coating reduces heat buildup and extends tool life in demanding materials. At 0.005 pounds, it is a precision cutting component installed and changed out by machining professionals and tool-room technicians. It belongs to the GEN3SYS XT series, engineered for aggressive feed rates and consistent hole geometry.

This insert is suited for drilling cast iron workpieces, classified under material grade K (ISO K20 / C2). It is commonly used in production machining environments including CNC machining centers and manual drill presses where spade drill tooling is specified. The GEN3SYS XT series targets applications requiring tight tolerances and reliable chip evacuation in ferrous and abrasive materials. Seat Size 18 compatibility limits holder selection to matching tooling within the GEN3SYS XT platform.

Key Features

• Solid carbide construction for rigidity and wear resistance in cast iron and abrasive materials
• AM300 PVD coating extends cutting edge life and reduces built-up edge formation
• 140-degree point angle optimizes entry and reduces thrust force
• Seat Size 18 interface for precise, repeatable insert indexing
• GEN3SYS XT series design supports high feed-rate drilling operations
• 0.46 inch insert height supports compact holder profiles

Compatibility

Designed for use with GEN3SYS XT series spade drill holders accepting Seat Size 18 inserts. Primary workpiece material is cast iron (ISO K, material grade C2 / K20).

Installation Notes

Insert seating and torquing should be performed by a qualified machinist or tooling technician following the holder manufacturer's clamping specifications. Power down and lock out the machine spindle before changing inserts. Inspect the seat pocket for chips or debris before installing a new insert, as contamination can affect seating accuracy and cause premature insert failure. Handle solid carbide inserts with care to avoid chipping the cutting edges prior to use.
