The ALLIED MACHINE AND ENGINEERING 452H-29.5 is a cobalt spade drill insert engineered for high-performance drilling in demanding industrial applications. Sized at 29.5 mm diameter with a Seat Size 2 designation, this insert features a 132-degree point angle and an AM200 PVD coating that extends tool life when cutting through hard, abrasive, or heat-generating workpiece materials. At 0.04 pounds and 0.1875 inches thick, it is a compact, precision-ground component designed for use in compatible T-A style spade drill holders. Machinists and tool-crib professionals in production and job-shop environments rely on this insert for repeatable, consistent hole quality.
This insert is rated for use across a broad range of primary workpiece materials including Steel (P), Stainless Steel (M), Cast Iron (K), Super-alloys and Titanium (S), and Hard Material (H). It is part of the GEN2 T-A series product line, making it suited for production drilling operations where insert changeability and consistent hole geometry are priorities. Typical applications include structural fabrication, aerospace component machining, and general metalworking where through-coolant or high-feed drilling is required in a machine shop or manufacturing cell environment.
Designed for use with GEN2 T-A series spade drill holders requiring a Seat Size 2 insert. Consult Allied Machine and Engineering tooling documentation to confirm correct holder and shank compatibility before ordering.
Insert changes should be performed with the machine powered down and locked out per applicable machine-shop lockout/tagout procedures. Use the correct torque driver and seating hardware specified by the holder manufacturer to avoid insert rocking or premature failure. Inspect the insert seat in the holder body for wear or debris before seating a new insert. Dispose of worn inserts according to applicable metal waste and hazardous material handling guidelines.
