Allied Machine 180T-.609 Spade Drill Insert 39/64 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 180T-.609 is a cobalt spade drill insert designed for high-performance drilling in demanding industrial applications. Measuring 39/64 inches in diameter with a 132-degree point angle, this insert features a TiN (Titanium Nitride) PVD coating that extends tool life and reduces friction at the cutting edge. Seat Size 0 and T-A Series designation make it a direct-fit replacement for compatible T-A spade drill holders. Licensed machinists and tool-room professionals install this insert when drilling through tough workpiece materials where a standard HSS insert would wear prematurely.

This insert is engineered for use across a broad range of workpiece materials including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials — covering ISO material codes P, M, K, S, and H. It is suited for production drilling operations in job shops, aerospace, and heavy manufacturing environments where consistent hole quality and tool longevity are priorities. The T-A Series interchangeable insert system allows fast changeover without removing the drill body from the spindle, reducing downtime on the floor.

Key Features

• 39/64 inch cutting diameter with 132-degree point angle for aggressive chip formation
• Cobalt substrate provides increased heat and wear resistance versus standard HSS
• TiN PVD coating reduces built-up edge and extends insert service life
• Seat Size 0 T-A Series configuration for direct holder compatibility
• Compatible with steel, stainless steel, cast iron, super-alloys, titanium, and hard materials
• 0.125 inch insert thickness for consistent seating and rigidity in the holder

Compatibility

Designed for use with T-A Series Seat Size 0 spade drill holders. Compatible workpiece materials include steel (P), stainless steel (M), cast iron (K), super-alloys and titanium (S), and hard materials (H) per ISO designation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill body and spindle are fully de-energized and locked out before changing inserts. Seat the insert firmly and evenly in the holder pocket before securing the clamping screw — do not force or over-torque beyond the holder manufacturer specification. Inspect the insert seat for chips or debris before each installation to maintain accurate positioning and safe cutting performance.
