Allied Machine 45YH-0012 Spade Drill Insert 3/8 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 45YH-0012 is a cobalt spade drill insert designed for high-performance hole-making in demanding metal-cutting applications. It features a 3/8 inch diameter, a 132-degree point angle, and an AM200 PVD coating that extends tool life when cutting abrasive or hard workpiece materials. The insert belongs to the GEN2 T-A series and uses a Seat Size Y holder interface. Machining professionals and tool-room technicians specify this insert for production drilling where edge retention and coating durability are critical to cycle-time and tool longevity.

This insert is suited for use in GEN2 T-A series spade drill holders with a Seat Size Y bore. Rated workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, making it applicable across general machining, aerospace component work, die and mold work, and heavy equipment manufacturing. The AM200 PVD coating is classified for use across ISO material groups P, M, K, S, and H.

Key Features

• 3/8 inch diameter, Seat Size Y — matches GEN2 T-A series spade drill holders

• Cobalt substrate provides toughness and heat resistance over standard HSS
• AM200 PVD coating extends wear life across steel, stainless, cast iron, super-alloys, and titanium
• 0.0938 inch insert thickness for consistent seating and repeatable geometry
• Weighs 0.1 pounds — lightweight for easy handling and quick changeout

Compatibility

Designed for use with ALLIED MACHINE AND ENGINEERING GEN2 T-A series spade drill holders requiring a Seat Size Y insert. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials (ISO groups P, M, K, S, and H).

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The machine spindle must be fully stopped and locked out before seating or removing the insert. Use the correct insert screw and torque driver specified by the holder manufacturer — do not substitute fasteners. Inspect the insert seat for chips or debris before installation to ensure proper seating and accurate geometry.
