Allied Machine 454T-0202 Spade Drill Insert 2-1/16 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 454T-0202 is a cobalt spade drill insert designed for high-performance drilling in demanding metalworking applications. This insert features a 132-degree point angle and a PVD-applied TiN (titanium nitride) coating for improved wear resistance and tool life. It carries a Seat Size 4 designation, placing it in the GEN2 T-A series platform. At 0.3125 inches thick and 2-1/16 inches in diameter, this insert is built for precision boring operations where dimensional accuracy and edge retention matter. It is installed and replaced by machinists and tooling technicians in production shop environments.

The 454T-0202 is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, covering ISO workpiece material codes P, M, K, S, and H. Typical applications include CNC machining centers and manual drill press setups where a modular spade drill system is used to achieve large-diameter holes with replaceable inserts rather than solid tooling. The GEN2 T-A platform is a modular spade drill system where the insert seats into a compatible holder body for rigid, repeatable tool positioning.

Key Features

• 2-1/16 inch diameter with 132-degree point angle for efficient chip formation and accurate hole entry
• Cobalt substrate provides elevated heat and wear resistance compared to standard high-speed steel
• PVD TiN coating extends tool life and reduces friction at the cutting edge
• Seat Size 4 designation ensures direct fitment into compatible GEN2 T-A series holder bodies
• 0.3125 inch insert thickness supports stability under high feed and interrupted cut conditions
• Compatible workpiece materials span P, M, K, S, and H ISO material codes for broad application coverage

Compatibility

Designed for use with Seat Size 4 holder bodies in the ALLIED MACHINE AND ENGINEERING GEN2 T-A spade drill platform. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials (ISO codes P, M, K, S, H).

Installation Notes

Installation is performed by a qualified machinist or tooling technician. The machine spindle must be fully stopped and the tool holder secured or removed from the spindle before replacing the insert. Use the appropriate insert screw and torque driver specified by the holder manufacturer to seat the insert correctly — do not overtighten or substitute fasteners. Verify insert seating and runout before resuming cutting operations.
