Allied Machine 453H-37.5 Spade Drill Insert 37.5mm Cobalt GEN2

Product Description

The ALLIED MACHINE AND ENGINEERING 453H-37.5 is a cobalt spade drill insert designed for high-performance hole making in demanding industrial and machining applications. With a 37.5 mm diameter and a 132-degree point angle, this insert delivers precise entry geometry and consistent chip formation. The AM200 PVD coating provides enhanced wear resistance and surface hardness, extending tool life across high-volume drilling cycles. At 0.25 inches thick, the insert fits the GEN2 T-A holder system at Seat Size 3. It is a direct-replacement consumable installed by machinists and CNC operators in production and job-shop environments.

This insert is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The GEN2 T-A platform is a modular spade drilling system commonly used on CNC machining centers, lathes, and drill presses where through-coolant capability and repeatability are required. The 453H-37.5 is a single-insert replacement that allows worn tooling to be swapped at the spindle without replacing the full holder assembly, reducing downtime and per-hole tooling cost.

Key Features

• 37.5 mm diameter with 132-degree point angle for precise entry and reduced thrust force
• Cobalt substrate provides toughness and heat resistance in interrupted cuts and difficult materials
• AM200 PVD coating classification increases surface hardness and reduces built-up edge on coated-tool-sensitive materials
• Compatible with GEN2 T-A modular spade drill holder system at Seat Size 3
• Rated for use in steel (P), stainless steel (M), cast iron (K), super-alloys and titanium (S), and hard materials (H)
• Lightweight at 0.08 pounds for easy handling and quick changeover

Compatibility

Designed for use with GEN2 T-A series spade drill holders at Seat Size 3. Specific holder compatibility should be confirmed against ALLIED MACHINE AND ENGINEERING GEN2 T-A tooling documentation before installation.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. The machine spindle must be fully stopped and locked out before seating or removing the insert. Use the manufacturer-specified torx or hex key to secure the insert screw to the holder seat; do not over-tighten or substitute fasteners. Verify insert seating and runout with a dial indicator before resuming production cuts.
