Allied Machine 452H-0100 Spade Drill Insert 1in Cobalt AM200

Product Description

The ALLIED MACHINE AND ENGINEERING 452H-0100 is a cobalt spade drill insert designed for high-performance drilling in demanding metal-cutting applications. Built to GEN2 T-A series specifications, it features a 132-degree point angle and an AM200 PVD coating that extends tool life and resists heat buildup at the cutting edge. The insert measures 1 inch in diameter with a Seat Size 2 designation, making it a direct fit for compatible T-A spade drill holders. At 0.1 inches thick (0.1875 inches decimal), it is a precision-ground consumable intended for production or maintenance machining environments. Machinists and tooling specialists install and replace these inserts during scheduled tooling changes or when edge wear requires rotation.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The AM200 PVD coating and cobalt substrate make it appropriate for applications where heat and abrasion resistance are critical, such as continuous drilling cycles in ferrous and exotic alloy workpieces. It is commonly used in CNC machining centers, drill presses, and manual mill-drill setups where T-A style spade drill holders are already in service. The GEN2 T-A series platform is a widely used indexable drilling system, and this insert is a standard replacement unit for that tooling family.

Key Features

• 1 inch cutting diameter with Seat Size 2 for direct T-A holder fitment
• 132-degree point angle optimized for entry and chip formation in hard materials
• Cobalt insert material provides toughness and heat resistance beyond standard HSS
• AM200 PVD coating extends edge life and reduces built-up edge on ferrous workpieces
• Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials
• GEN2 T-A series design for use with existing Allied Machine T-A spade drill holders

Compatibility

Designed for use with Allied Machine and Engineering GEN2 T-A series spade drill holders accepting a Seat Size 2 insert. Compatible workpiece material classifications include P (steel), M (stainless steel), K (cast iron), S (super-alloys and titanium), and H (hard materials).

Installation Notes

Insert replacement is performed by a machinist or tooling technician. Always power down and lock out the machine before removing or seating a spade drill insert. Use the manufacturer-recommended torque wrench or insert key to secure the insert screw — do not overtighten by hand or with improvised tools. Inspect the holder seat for chips or debris before installing a new insert to ensure proper seating and runout.
