Allied Machine 452H-34 Spade Drill Insert 34mm Cobalt GEN2 T-a

Product Description

The ALLIED MACHINE AND ENGINEERING 452H-34 is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. Built to GEN2 T-A series specifications, this insert features a 132-degree point angle and an AM200 PVD coating that extends tool life and maintains edge integrity under heavy cutting loads. At 0.1875 inches thick, the insert seats into a Seat Size 2 holder and is engineered for consistent positioning and repeatable hole quality. It is suited for use in CNC machining centers, lathes, and drilling machines where rigid setups and high metal-removal rates are required.

This insert is intended for use in industrial and production machining environments. It is rated for drilling into a broad range of workpiece materials including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The AM200 PVD coating provides thermal and wear resistance across these material categories, making this insert a versatile option for job shops and production facilities running varied material stock. Installation is performed by machinists and tooling technicians maintaining spade drill tooling assemblies.

Compatibility

Designed for use with ALLIED MACHINE AND ENGINEERING GEN2 T-A series spade drill holders accepting a Seat Size 2 insert. Verify holder seat size and series before installation.

Installation Notes

Installation and insert changes should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked. Use the appropriate torque wrench and insert screw specified for the T-A series holder to secure the insert without over-tightening. Inspect the insert seat for chips, debris, or wear before seating the new insert, as contamination affects positioning accuracy and can damage the holder. Follow the holder manufacturer guidelines for insert torque sequence and coolant setup before returning the assembly to service.
