Allied Machine 454T-0212 Spade Drill Insert 2-3/8 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 454T-0212 is a spade drill insert engineered for high-performance drilling in demanding industrial and machining applications. Measuring 2-3/8 inches in diameter with a 132-degree point angle, this insert seats at Size 4 and is manufactured from Super Cobalt with a PVD-applied Titanium Nitride (TiN) coating. The TiN coating reduces friction and extends tool life in abrasive cutting conditions. At 0.1 pounds, it is a compact, precision-ground insert intended for use in compatible T-A style spade drill holders. Installation is performed by machining professionals in shop and production environments.

The 454T-0212 is suited for drilling operations across a range of primary workpiece materials including Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, and Hard Materials, corresponding to ISO material groups P, M, K, S, and H. It is part of the GEN2 T-A series and is designed for fractional inch tooling systems. Typical applications include production drilling in CNC machining centers, manual drill presses, and heavy-duty boring setups where consistent hole geometry and extended insert life are required.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine powered down and locked out per applicable lockout/tagout procedures. Use the correct torque driver or insert wrench for the seat fastener to avoid damaging the seating surface. Inspect the holder pocket and fastener for wear or debris before seating the new insert. Consult the holder manufacturer guidelines for proper clamping procedure.
