Allied 150T-0018-FB Spade Drill Insert 9/16 in Cobalt Tin 180 Pt

Product Description

The ALLIED MACHINE AND ENGINEERING 150T-0018-FB is a spade drill insert designed for high-performance drilling in demanding metalworking applications. With a 9/16 inch diameter, a 180-degree point angle, and a cobalt substrate with a TiN (titanium nitride) PVD coating, this insert delivers extended tool life and heat resistance in tough materials. At 0.125 inches thick and rated for Seat Size 0, it mounts into compatible T-A series spade drill holders. It is installed and used by machinists, toolroom technicians, and production drilling operations requiring consistent hole quality across a range of workpiece materials.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, and titanium, making it a versatile choice for job shops and production environments handling mixed-material workloads. The T-A series is a widely used modular spade drilling system that separates the cutting insert from the holder body, allowing insert changes without removing the holder from the machine. Typical applications include through-hole and blind-hole drilling on CNC machining centers, lathes, and drill presses where precise diameter and point geometry are critical.

Key Features

• 9/16 inch diameter with a 180-degree point angle for flat-bottomed and standard through-hole drilling
• Cobalt substrate provides increased hardness and heat resistance compared to standard HSS inserts
• TiN PVD coating reduces friction, improves wear resistance, and extends cutting life
• Seat Size 0 fits T-A series spade drill holders for quick insert changeout
• 0.125 inch insert thickness maintains rigidity during high-feed drilling operations
• Rated for primary workpiece materials including steel, stainless steel, cast iron, super-alloys, and titanium

Compatibility

Designed for use with T-A series Seat Size 0 spade drill holders. Compatible primary workpiece material classifications include P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium) per ISO material coding standards.

Installation Notes

Insert replacement should be performed with the machine fully powered down and the spindle locked. Use the appropriate torque screwdriver or insert key specified for the T-A series holder to seat the insert securely without over-torquing the retention screw. Inspect the holder pocket and seating surfaces for chips or debris before installing a new insert. Follow the machine tool manufacturer and cutting tool guidelines for recommended speeds and feeds based on workpiece material.
