Allied 7C116P-.640 Spade Drill Insert 41/64 in Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 7C116P-.640 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. It features a 140-degree point angle and an AM300 PVD coating, which improves wear resistance and extends tool life in demanding applications. Sized at 41/64 inches in diameter with a Seat Size 16, this insert fits the GEN3SYS XT platform. It is installed by machinists and toolroom technicians working on CNC machining centers and drill presses where consistent hole quality and insert interchangeability are required.

This insert is suited for production drilling in ferrous metals, including steel and hard workpiece materials. The GEN3SYS XT series is a modular spade drilling system, and this insert is selected when the application demands a carbide cutting edge over high-speed steel alternatives. Typical use cases include through-hole and blind-hole drilling operations in job shop, aerospace, and general manufacturing environments where material hardness and tool longevity are primary concerns.

Key Features

• 41/64 inch diameter, Seat Size 16, compatible with GEN3SYS XT spade drill holders
• Solid carbide construction — Manufacturer Grade C1 (K35) — for rigidity and wear resistance
• AM300 PVD coating for improved performance in steel and hard material drilling
• 140-degree point angle reduces thrust and improves chip formation on entry
• 0.4 inch insert height provides consistent seating geometry in modular holders
• Single-insert packaging with a minimum order quantity of 1

Compatibility

Designed for use with GEN3SYS XT series spade drill holders requiring a Seat Size 16 insert. Rated for primary workpiece materials classified as Steel (P) and Hard Material (H) per ISO material group codes.

Installation Notes

Spade drill insert replacement is performed by machining technicians. Before changing an insert, power down the spindle and confirm the machine is in a safe, locked-out state per applicable machine guarding procedures. Seat the insert flush against the holder pocket and secure with the retaining screw using the appropriate Torx or hex key driver — do not over-tighten or substitute fasteners. Inspect the holder seat for chips or debris before installing a new insert to ensure proper seating and runout.
