Allied Machine 454H-0216 Spade Drill Insert 2.5 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 454H-0216 is a cobalt spade drill insert designed for high-performance hole-making in demanding metal-cutting applications. With a 2.5-inch cutting diameter and a 132-degree point angle, this insert delivers precise entry geometry and efficient chip evacuation across a wide range of workpiece materials. The AM200 PVD coating enhances surface hardness and heat resistance, extending tool life under heavy-feed conditions. It is sized to Seat Size 4 and belongs to the GEN2 T-A series, a system widely used in production machining environments by machinists and tool-and-die professionals.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It performs in both roughing and production drilling scenarios where consistent hole quality and insert interchangeability are required. The GEN2 T-A spade drill system is commonly found in CNC machining centers, lathes with live tooling, and manual boring mills across job shop and production floor environments. Each package contains one insert.

Key Features

• 2.5-inch cutting diameter for large-bore spade drilling applications
• 132-degree point angle for controlled entry and reduced thrust force
• Cobalt substrate provides high heat resistance and toughness in difficult-to-machine alloys
• AM200 PVD coating extends tool life and improves performance on steel, stainless, cast iron, super-alloys, titanium, and hard materials
• Seat Size 4 fits GEN2 T-A series spade drill holders
• 0.3125-inch insert thickness for rigid, stable seating in the holder pocket

Compatibility

Designed for use with GEN2 T-A series Seat Size 4 spade drill holders. Compatible workpiece materials include steel (P), stainless steel (M), cast iron (K), super-alloys and titanium (S), and hard materials (H) per ISO material classification.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's insert seating and torque procedures. Ensure the holder pocket and seating surfaces are clean and free of chips before placing the insert. Power down and lock out the machine spindle before any insert change. Follow the machine manufacturer's guidelines and applicable shop safety standards when handling sharp cutting inserts.
