Allied 150T-.515-FB Spade Drill Insert 33/64 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 150T-.515-FB is a spade drill insert engineered for high-performance hole-making in demanding machining applications. This insert measures 33/64 inches in diameter with a 0.125-inch thickness and features a 180-degree point angle for accurate, self-centering entry on flat or contoured workpiece surfaces. Manufactured from cobalt high-speed steel and finished with a Physical Vapor Deposition (PVD) titanium nitride (TiN) coating, it delivers extended cutting life and improved wear resistance compared to uncoated inserts. It belongs to the T-A Series, a widely used modular spade drill system designed for interchangeable insert replacement.

This insert is suited for production drilling operations in job shops, manufacturing facilities, and machining centers where operators need a reliable replacement insert for T-A Series spade drill holders. The cobalt substrate and TiN coating make it appropriate for cutting steel, stainless steel, cast iron, super-alloys, and titanium. Seat Size 0 designates the holder interface, and machinists should confirm their holder matches this seat size before installation. This item is sold individually but must be ordered in multiples of two per the manufacturer minimum order requirement.

Key Features

• 33/64-inch diameter with 180-degree point angle for flat-bottom entry and accurate hole location
• Cobalt high-speed steel construction provides toughness and heat resistance in difficult-to-machine materials
• PVD TiN coating extends cutting life and reduces built-up edge in ferrous and exotic alloys
• T-A Series Seat Size 0 interface for direct replacement in compatible modular spade drill holders
• 0.125-inch insert thickness for consistent seating and repeatable drilling depth
• Rated for steel (P), stainless steel (M), cast iron (K), and super-alloys and titanium (S) workpiece materials

Compatibility

Designed for use with T-A Series modular spade drill holders accepting Seat Size 0 inserts. Confirm holder seat size and insert diameter match before ordering.

Installation Notes

Spade drill insert replacement is performed by qualified machinists following established toolroom practices. Ensure the machine spindle is fully powered down and locked out before removing or installing any insert. Seat the insert fully against the holder pocket and torque the clamping screw according to the holder manufacturer specifications. Inspect the seat and clamping surfaces for chips or wear before installing a new insert to avoid seating errors that could affect hole quality or cause insert breakage.
