Allied Machine 180A-17.5 Spade Drill Insert 17.50mm Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 180A-17.5 is a spade drill insert designed for high-performance drilling in demanding metalworking applications. Built from premium cobalt with a PVD-applied TiAlN coating, this insert resists heat and wear during extended cutting cycles. The 132-degree point angle provides aggressive, self-centering entry into the workpiece. At 0.125 inches thick and 17.50 mm in diameter, it fits Seat Size 0 T-A series spade drill holders. Licensed machinists and tooling specialists install this insert in CNC turning centers, machining centers, and drill presses where consistent hole quality and insert longevity are priorities.

The 180A-17.5 is suited for drilling operations in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The TiAlN coating performs well in dry or minimal-lubrication cutting environments where surface temperatures are elevated. This insert is part of the T-A series, a modular spade drilling system that separates the blade from the holder, allowing individual insert replacement without discarding the full tool assembly. It is used in production and job-shop environments where material variety demands a versatile, coated cobalt insert.

Installation Notes

Spade drill insert replacement is performed by qualified machinists or tooling technicians. Before replacing the insert, ensure the machine is fully powered down, the spindle is locked, and all energy is isolated per LOTO procedures. Seat the insert flush against the holder pocket and torque the clamping screw to the holder manufacturer specification — do not substitute generic torque values. Inspect the holder seat for wear, chips, or debris before seating the new insert to ensure proper blade support and runout.
