The ALLIED MACHINE AND ENGINEERING 452H-30.5 is a cobalt spade drill insert designed for high-performance through-hole and blind-hole drilling operations. Built to GEN2 T-A series specifications, this insert measures 30.5 mm in diameter with a 132-degree point angle and a thickness of 0.1875 inches. The AM200 PVD coating improves wear resistance and thermal stability during high-speed cutting. Seat Size 2 ensures positive, repeatable seating in compatible T-A spade drill holders. This insert is intended for use by machinists and tooling professionals in production and job-shop environments where consistent hole quality and tool life are priorities.
This insert is rated for use across a broad range of primary workpiece materials including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It fits applications in aerospace, heavy equipment, energy, and general manufacturing where demanding workpiece materials require a coated cobalt cutting edge. The GEN2 T-A platform is a common choice for high-volume drilling on CNC machining centers and drill presses where insert changeability reduces downtime.
Designed for use with GEN2 T-A series Seat Size 2 spade drill holders. Suitable for workpiece materials classified under ISO codes P (steel), M (stainless steel), K (cast iron), S (super-alloys and titanium), and H (hard materials).
Installation is performed by qualified machinists or tooling technicians. The machine spindle must be fully stopped and locked out before inserting or replacing the spade drill insert. Confirm the holder seat is clean and free of chips or debris before seating the insert to ensure proper contact and accurate hole geometry. Follow the machine tool and holder manufacturer torque guidance for the clamping screw to avoid insert movement or damage during cutting.
