Allied Machine 150A-.609 Spade Drill Insert 39/64 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 150A-.609 is a spade drill insert designed for high-performance hole-making in metal cutting applications. This insert features a cobalt substrate with a TiAlN (titanium aluminum nitride) PVD coating, which improves wear resistance and heat tolerance during aggressive drilling cycles. With a 39/64 inch diameter, a 132-degree point angle, and a Seat Size 0 classification, this insert fits into the T-A spade drill holder system. At 0.125 inches thick and weighing 0.1 pounds, it is a compact, precision-ground component used by machinists and tooling technicians in production and job-shop environments.

This insert is intended for drilling operations across a broad range of workpiece materials, including steel, stainless steel, cast iron, super-alloys, and titanium. These material categories correspond to ISO classifications P, M, K, and S. It is suited for use in CNC machining centers, drill presses, and turning centers where a replaceable spade drill insert system is employed. The 132-degree point geometry is appropriate for general-purpose drilling into solid stock and is a common choice for through-hole and blind-hole applications in ferrous and exotic-alloy materials.

Key Features

• 39/64 inch cutting diameter with 132-degree point angle for general-purpose drilling

• TiAlN PVD coating enhances wear resistance and thermal stability
• Seat Size 0 fits T-A series spade drill holder bodies
• 0.125 inch insert thickness for precise seating and rigidity
• Compatible with steel, stainless steel, cast iron, super-alloys, and titanium workpieces

Compatibility

Designed for use with Allied Machine and Engineering T-A series Seat Size 0 spade drill holders. Suitable for workpiece materials classified under ISO material groups P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before removing or seating the insert. Ensure the holder pocket and clamping screw are clean and free of chips before seating the insert, as debris under the insert can cause premature failure or dimensional drift. Follow the holder manufacturer's clamping torque guidelines and inspect the insert for seating contact before resuming cutting operations.
