Allied 450H-.640 Spade Drill Insert 41/64 in Cobalt GEN2 T-a

Product Description

The ALLIED MACHINE AND ENGINEERING 450H-.640 is a spade drill insert designed for high-performance drilling in demanding metalworking applications. The insert measures 41/64 inches in diameter with a 132-degree point angle and is manufactured from Super Cobalt material. It features an AM200 PVD coating that extends tool life and improves performance in abrasive and hard materials. The 0.125-inch thickness and Seat Size 0 profile make it compatible with the GEN2 T-A spade drill system. This insert is intended for use by machinists, tool and die professionals, and production drilling operations working in metal fabrication environments.

The 450H-.640 is rated for use across a broad range of primary workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. These material compatibility designations correspond to ISO material codes P, M, K, S, and H. It fits into the GEN2 T-A holder series, which is a modular spade drill platform common in CNC machining centers and manual drill press setups requiring precise, repeatable hole geometry in production or job shop environments.

Key Features

• 41/64-inch diameter with a 132-degree point angle for controlled entry and reduced thrust in harder materials
• Super Cobalt insert material provides elevated heat and wear resistance compared to standard HSS inserts
• AM200 PVD coating classification improves surface hardness and lubricity across all rated material groups
• Seat Size 0 insert profile fits GEN2 T-A spade drill holders directly
• Rated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO P, M, K, S, H)
• Fractional inch system sizing for straightforward integration with inch-based tooling setups

Compatibility

Designed for use with GEN2 T-A series spade drill holders. Fits Seat Size 0 holder configurations within the Allied Machine and Engineering modular spade drill platform.

Installation Notes

Installation of spade drill inserts should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before removing or seating any insert. Ensure the holder seat and insert seating surfaces are clean and free of chips or debris before securing the insert. Follow the holder manufacturer's clamping procedure and verify insert seating before resuming cutting operations.
