Allied Machine 454H-0203 Spade Drill Insert 2-3/32 in

Product Description

The ALLIED MACHINE AND ENGINEERING 454H-0203 is a cobalt spade drill insert designed for high-performance hole-making in demanding metalworking applications. Part of the GEN2 T-A series, this insert features a 132-degree point angle and an AM200 PVD coating that extends tool life and reduces friction at the cutting edge. At 2-3/32 inches in diameter and 0.3125 inches thick, it fits Seat Size 4 T-A spade drill holders. Licensed machinists and tool-and-die professionals install this insert as a replaceable cutting element, keeping holder costs low while maintaining consistent bore quality across production runs.

This insert is rated for use in a wide range of primary workpiece materials, including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is well suited to high-volume drilling in job shops, production machining environments, and maintenance operations where interrupted cuts, tough alloys, or abrasive materials demand a cobalt substrate over standard high-speed steel. The AM200 coating provides added wear resistance in these difficult-to-machine material categories.

Key Features

• Cobalt substrate with AM200 PVD coating for extended wear life in steel, stainless, and superalloy applications
• 132-degree point angle suited to a broad range of metalworking materials and entry conditions
• 2-3/32 inches cutting diameter with 0.3125 inches insert thickness for rigid, stable cutting geometry
• Seat Size 4 compatibility fits standard GEN2 T-A spade drill holders
• Material Grade C5 cobalt classification supports interrupted cuts and high feed rates
• Fractional inch system for straightforward sizing and replacement in inch-based machine shops

Compatibility

Designed for use with Seat Size 4 GEN2 T-A series spade drill holders. Compatible with primary workpiece materials classified as steel, stainless steel, cast iron, superalloys and titanium, and hard materials per ISO material codes P, M, K, S, and H.

Installation Notes

This insert is installed and replaced by machinists or tool-room technicians following the holder manufacturer torque and clamping specifications for T-A series holders. Always power down and lock out the spindle before seating or removing the insert. Inspect the holder seat for chips or wear before installing a new insert to ensure proper seating and prevent premature edge failure. Follow applicable shop safety and machine guarding practices when working with rotary cutting tools.
