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

Product Description

The ALLIED MACHINE AND ENGINEERING 150T-.515 is a spade drill insert engineered for high-performance hole-making in demanding industrial and metalworking applications. Sized at 33/64 inch in diameter with a 132-degree point angle, this insert is manufactured from T15 cobalt high-speed steel and finished with a Physical Vapor Deposition (PVD) TiN (titanium nitride) coating. The TiN coating reduces friction and increases surface hardness, extending tool life in abrasive cutting conditions. At 0.125 inch thickness, this insert fits Seat Size 0 holders in the T-A series system. It is designed for machinists and tooling specialists working in production drilling environments where consistent geometry and material compatibility are critical.

This insert is suited for drilling steel, stainless steel, cast iron, superalloys, and titanium. It carries primary workpiece material codes P, M, K, and S, covering a broad range of ferrous and high-temperature alloys commonly encountered in aerospace, oil and gas, and general metalworking shops. The T-A series modular design allows the insert to be replaced independently from the holder body, making it a cost-effective solution for high-volume drilling operations where insert changeover speed matters.

Key Features

• 33/64 inch diameter with 132-degree point angle for aggressive, self-centering entry
• T15 cobalt high-speed steel construction for toughness in difficult-to-machine alloys
• PVD TiN coating reduces wear and improves chip evacuation in ferrous materials
• Seat Size 0 insert fits T-A series spade drill holders for modular tooling systems
• Compatible with steel, stainless steel, cast iron, superalloys, and titanium workpieces
• Fractional inch measurement system for straightforward tool selection and documentation

Compatibility

Designed for use with T-A series Seat Size 0 spade drill holder bodies. Compatible with primary workpiece materials classified under codes P (steel), M (stainless steel), K (cast iron), and S (superalloys and titanium) per standard ISO material designation.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or tooling technician with the machine fully powered down and at a complete stop. Use the appropriate T-A series seat and fastener hardware specified by the holder manufacturer to secure the insert correctly. Inspect the seat pocket for debris or damage before seating a new insert. Follow the tooling manufacturer's feed and speed recommendations for the specific workpiece material being drilled.
