Allied Machine 450H-0020 Spade Drill Insert 5/8 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 450H-0020 is a cobalt spade drill insert designed for high-performance drilling in demanding metalworking applications. With a 5/8 inch diameter, a 132-degree point angle, and an AM200 PVD coating, this insert delivers controlled cutting geometry and extended tool life in tough workpiece materials. It fits the GEN2 T-A spade drill system using a Series Code 0 seat size. Licensed machinists and tooling specialists install these inserts as replaceable cutting elements in T-A style spade drill holders, making them a cost-effective consumable for production drilling operations.

This insert is engineered for use across a broad range of primary workpiece materials, including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It is suited for both production-volume and maintenance machining environments where precise hole quality and repeatable performance are required. The GEN2 T-A platform is commonly used in vertical machining centers, CNC lathes with live tooling, and manual drill presses where spade-style tooling is appropriate.

Key Features

• 5/8 inch diameter with 132-degree point angle for accurate entry and reduced thrust force
• Cobalt substrate provides heat resistance and toughness in difficult-to-machine alloys
• AM200 PVD coating enhances wear resistance and extends insert service life
• Series Code 0 seat size fits GEN2 T-A spade drill holder bodies
• 0.125 inch insert thickness for consistent seating depth and stable cutting geometry
• Compatible with steel, stainless steel, cast iron, super-alloys, titanium, and hard materials

Compatibility

Designed for use with GEN2 T-A spade drill holders requiring a Series Code 0 seat size. Compatible primary workpiece material classifications include P (steel), M (stainless steel), K (cast iron), S (super-alloys and titanium), and H (hard materials).

Installation Notes

Spade drill inserts are installed and replaced by qualified machinists or tooling technicians. Power down and lock out the machine before removing or seating an insert. Ensure the holder pocket and seating surfaces are clean and free of chips or debris before installing the insert, as contamination can cause misalignment and premature failure. Follow the tool manufacturer torque and clamping guidelines for the specific holder body being used.
