Allied Machine 452H-0103 Spade Drill Insert 1-3/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 452H-0103 is a cobalt spade drill insert designed for high-performance drilling in demanding metal-cutting applications. It features a 132-degree point angle and an AM200 PVD coating applied through physical vapor deposition, which extends tool life in abrasive and high-heat conditions. The insert seats in a Size 2 holder from the GEN2 T-A series and measures 0.1875 inches thick with a 1-3/32 inch diameter cutting edge. Machining professionals, tool-and-die shops, and production drilling operations use this insert as a replaceable cutting element, reducing the cost of tooling versus replacing an entire drill body.

This insert is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials — covering ISO workpiece material codes P, M, K, S, and H. The GEN2 T-A platform is a modular spade drill system, so this insert pairs with a compatible Size 2 T-A blade holder and drill body. It is appropriate for CNC machining centers, lathes with live tooling, and manual drill presses where the operator uses a standard T-A holder setup. It is sold individually and ordered in single-unit quantities.

Key Features

• 1-3/32 inch diameter cutting edge for precise hole sizing
• 132-degree point angle reduces thrust and improves chip formation
• Cobalt substrate provides heat resistance and edge retention in tough alloys
• AM200 PVD coating extends tool life in steel, stainless steel, and hard materials
• GEN2 T-A Series Size 2 seat interface for secure, repeatable insert indexing
• Covers five ISO workpiece material groups: P, M, K, S, and H

Compatibility

Designed for use with GEN2 T-A Series Size 2 spade drill blade holders and bodies. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials as specified by the manufacturer.

Installation Notes

Installation of spade drill inserts is performed by machinists or tooling technicians. Before changing an insert, ensure the machine spindle is fully stopped and locked out per your facility lockout/tagout procedure. Seat the insert firmly in the Size 2 pocket and torque the clamping screw according to the holder manufacturer specifications — do not over-torque, as this can damage the insert seat. Inspect the blade holder pocket for wear or debris before seating a new insert.
