Allied Machine 452H-0106 Spade Drill Insert 1-3/16 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 452H-0106 is a cobalt spade drill insert designed for high-performance drilling in demanding industrial applications. Built to GEN2 T-A series specifications, this insert features a 132-degree point angle and a Seat Size 2 designation, making it a direct-mount solution for compatible T-A spade drill holders. The AM200 PVD coating provides enhanced wear resistance and thermal stability, extending tool life in abrasive and hard-to-machine materials. At 0.1875 inches thick and a cutting diameter of 1-3/16 inches, this insert delivers precise hole geometry with consistent performance across production runs. Installation is performed by qualified machinists in CNC or manual drilling operations.

The 452H-0106 is suited for drilling operations on steel, stainless steel, cast iron, super-alloys, titanium, and hard materials — covering ISO material groups P, M, K, S, and H. It is commonly used in general machining, aerospace component manufacturing, heavy equipment fabrication, and tool and die applications where consistent bore diameter and surface finish are required at depth. The GEN2 T-A series design supports through-coolant delivery when paired with an appropriate holder, improving chip evacuation and thermal management in deep-hole drilling scenarios.

Key Features

• 1-3/16 inch cutting diameter with Seat Size 2 for GEN2 T-A series holders
• 132-degree point angle for reduced thrust and accurate hole entry
• Cobalt substrate provides toughness and heat resistance in interrupted cuts
• AM200 PVD coating enhances wear resistance across multiple workpiece material groups
• Compatible with ISO material groups P, M, K, S, and H — steel through hard materials
• Insert thickness of 0.1875 inches for stable seating and repeatable indexing

Compatibility

Designed for use with ALLIED MACHINE AND ENGINEERING GEN2 T-A series spade drill holders accepting Seat Size 2 inserts at 1-3/16 inch diameter. Verify holder seat size and series designation before ordering.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before indexing or replacing the insert. Seat the insert fully against the holder pocket and torque the clamping screw to the holder manufacturer's specified value using a calibrated torque driver — do not over-tighten. Inspect the insert seat for chips or debris before each installation to ensure proper seating and accurate diameter.
