Allied 450H-.578 Spade Drill Insert 37/64 in Cobalt 132 Deg

Product Description

The ALLIED MACHINE AND ENGINEERING 450H-.578 is a spade drill insert designed for use in modular spade drilling systems. It features a 37/64-inch diameter, a 132-degree point angle, and is manufactured from Super Cobalt with an AM200 PVD coating. The AM200 coating improves wear resistance and heat tolerance, making this insert suitable for demanding drilling applications in ferrous and hard materials. Machinists, tool-and-die technicians, and CNC operators install this insert into compatible T-A spade drill holders as part of the GEN2 T-A system. At 0.125 inches thick and 0.1 pounds, it is a compact, precisely ground cutting tool intended for production drilling environments.

This insert is part of the GEN2 T-A series from Allied Machine and Engineering and is sized for Seat Size 0 holders. It is suited for drilling into a wide range of workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Typical applications include production machining on CNC machining centers and drill presses where consistent hole quality and tool life are critical. The fractional inch sizing system makes this insert straightforward to specify for inch-based machining setups.

Key Features

• 37/64-inch diameter with 132-degree point angle for reduced thrust in deep-hole drilling
• Super Cobalt substrate provides elevated heat and wear resistance compared to standard HSS
• AM200 PVD coating extends tool life in steel, stainless steel, cast iron, superalloys, titanium, and hard materials
• GEN2 T-A series design for compatibility with Allied T-A spade drill holders
• Seat Size 0 for use in corresponding holder seat configurations
• 0.125-inch thickness maintains precise seating geometry in the holder pocket

Compatibility

Designed for use with Allied Machine and Engineering GEN2 T-A series spade drill holders sized for Seat Size 0 inserts. Suitable for primary workpiece material codes P, M, K, S, and H as defined by ISO material classification.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always ensure the machine spindle is fully stopped and the machine is locked out before changing spade drill inserts. Seat the insert fully and evenly in the holder pocket before torquing the clamp screw; use the tooling manufacturer's recommended insert wrench and follow the holder manufacturer's clamping specifications. Inspect the seat and insert seating surfaces for chips or debris before each installation to prevent insert rocking or premature failure.
