Allied Machine 433T-0115 Spade Drill Insert 1-15/32 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 433T-0115 is a high speed steel spade drill insert designed for use in modular spade drilling systems. This insert features a 1-15/32 inch diameter, a 132-degree point angle, and a physical vapor deposition (PVD) titanium nitride (TiN) coating applied over an M4 grade high speed steel substrate. The TiN coating reduces friction and improves wear resistance during high-feed drilling operations. It fits Seat Size 3 tool holders in the GEN2 T-A series platform. Licensed machinists and tool-and-die professionals install this insert in production drilling applications where consistent hole quality and extended tool life are required.

This insert is suited for drilling steel, cast iron, and non-ferrous metals, covering ISO material groups P, K, and N. It is a common choice in job shop and production machining environments where spade drill bodies are already in use. The GEN2 T-A series is a widely adopted modular platform, and this insert indexes directly into compatible Seat Size 3 holders without additional modification. Applications include through-hole and flat-bottom drilling in structural steel, gray iron castings, and aluminum alloys.

Key Features

• 1-15/32 inch diameter for precise hole sizing in modular spade drilling setups
• 132-degree point angle reduces thrust and improves chip evacuation in hard materials
• M4 high speed steel substrate provides toughness and resistance to thermal fatigue
• TiN PVD coating extends insert life by reducing built-up edge and abrasive wear
• Seat Size 3 indexing compatible with GEN2 T-A series spade drill bodies
• Rated for steel, cast iron, and non-ferrous metal workpiece materials

Compatibility

Designed for use with Seat Size 3 tool holders in the ALLIED MACHINE AND ENGINEERING GEN2 T-A spade drill series. Suitable for workpiece materials classified under ISO groups P (steel), K (cast iron), and N (non-ferrous metal).

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The machine spindle must be fully stopped and locked out before seating or removing the insert. Use the correct torx or hex key specified by the tool body manufacturer to secure the insert screw to the recommended seating torque range for the holder size. Inspect the insert seat and clamping screw for chips or damage before each insert change to ensure proper seating and runout control.
