Allied Machine 453T-0122 Spade Drill Insert 1-11/16 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 453T-0122 is a cobalt spade drill insert designed for high-performance hole-making in a wide range of metalworking applications. Part of the GEN2 T-A series, this insert measures 1-11/16 inches in diameter and seats in a Size 3 holder. It features a 132-degree point angle and a TiN (Titanium Nitride) PVD coating that extends tool life by reducing friction and heat buildup at the cutting edge. Material grade M4 cobalt construction provides toughness and wear resistance in demanding drilling operations. This insert is installed by machinists and tooling technicians in CNC and manual drilling setups.

The 453T-0122 is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The GEN2 T-A system uses a modular design where the insert mounts to a dedicated holder, making it a practical choice for production environments where insert changeout speed and repeatability matter. It is commonly used in job shops, aerospace machining, and heavy manufacturing where consistent hole geometry and tool longevity are required across varying workpiece materials.

Key Features

• 1-11/16 inch cutting diameter with Seat Size 3 for GEN2 T-A holders
• 132-degree point angle for reduced thrust and accurate entry
• M4 cobalt construction for toughness in interrupted cuts and abrasive materials
• TiN PVD coating reduces cutting temperatures and extends insert life
• Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials
• Modular insert design allows fast changeout without removing the holder from the spindle

Compatibility

Designed for use with GEN2 T-A series Seat Size 3 spade drill holders from ALLIED MACHINE AND ENGINEERING. Compatible with primary workpiece material codes P (steel), M (stainless steel), K (cast iron), S (super-alloys and titanium), and H (hard materials).

Installation Notes

This insert is installed and changed out by machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before handling or replacing any cutting insert. Seat the insert fully and verify it is secure in the holder before resuming any cutting operation. Follow the holder manufacturer torque and clamping guidelines for the GEN2 T-A system when securing the insert screw.
