Allied Machine 180A-.578 Spade Drill Insert 37/64 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 180A-.578 is a spade drill insert designed for high-performance hole-making in a wide range of demanding workpiece materials. Manufactured from cobalt high-speed steel and finished with a TiAlN (Titanium Aluminum Nitride) PVD coating, this insert delivers improved heat resistance and extended tool life compared to uncoated alternatives. It features a 132-degree point angle suited for consistent entry geometry and reduced thrust on harder materials. The insert measures 0.125 inches in thickness and carries a seat size of 0, placing it in the T-A series product family. It is sold individually and is installed by machinists and tooling technicians in production and job-shop environments.

This insert is designed for use in T-A series spade drill bodies with a seat size 0 designation. It is rated for drilling into multiple primary workpiece material categories including steel, stainless steel, cast iron, super-alloys and titanium, and hard materials, making it suitable for aerospace, energy, heavy equipment, and general metalworking applications. The TiAlN coating provides oxidation resistance at elevated cutting temperatures, which is particularly relevant when drilling super-alloys and titanium at higher surface speeds.

Key Features

• 37/64 inch diameter cobalt spade drill insert for aggressive material removal
• 132-degree point angle for controlled entry and reduced axial thrust
• TiAlN PVD coating for elevated heat and wear resistance
• Rated for steel, stainless steel, cast iron, super-alloys, titanium, and hard materials
• T-A series, seat size 0 — mates with compatible Allied T-A spade drill holders
• 0.125 inch insert thickness for consistent seating in the drill body pocket

Compatibility

Designed for use with Allied Machine and Engineering T-A series spade drill bodies requiring a seat size 0 insert. Consult the T-A series tooling guide to confirm holder compatibility before installation.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the drill body pocket and clamping screw are clean and free of chips before seating the insert, as debris under the insert can cause premature failure or runout. Use the correct torque driver and manufacturer-specified screw for the seat size to avoid stripping the clamping interface. Power down and lock out the machine spindle before performing any insert change.
