Allied Machine 454H-0206 Spade Drill Insert 2-3/16 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 454H-0206 is a spade drill insert engineered for high-performance drilling in demanding industrial and machining applications. Manufactured from Super Cobalt with an AM200 PVD coating, this insert delivers extended tool life and heat resistance when cutting through hard and abrasive workpiece materials. It features a 2-3/16 inch diameter, a 132-degree point angle, and is part of the GEN2 T-A series. Licensed machinists and tooling specialists install this insert into compatible spade drill holders for production drilling operations requiring tight tolerances and consistent performance across a range of materials.

This insert is suited for use in metalworking environments where multiple material types are encountered in a single production run or job shop setting. Its primary workpiece material classifications include Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, and Hard Materials, covering ISO P, M, K, S, and H material groups. The GEN2 T-A series design supports repeatable insert indexing and consistent hole geometry in both manual and CNC drilling setups.

Key Features

• 2-3/16 inch diameter with a 132-degree point angle for aggressive chip formation and accurate entry
• Super Cobalt substrate provides elevated hardness and thermal resistance compared to standard HSS
• AM200 PVD coating reduces friction and extends cutting edge life in difficult-to-machine materials
• GEN2 T-A series geometry supports use in a broad range of ISO material groups: P, M, K, S, and H
• Seat Size 4 for compatibility with matching GEN2 T-A spade drill holders
• Fractional inch measurement system for straightforward specification matching in imperial tooling setups

Compatibility

Designed for use with Seat Size 4 GEN2 T-A series spade drill holders. Verify holder seat size and series designation before installation. No additional specific model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill holder is fully removed from the spindle or machine tool and all power is locked out before inserting or replacing the insert. Use the appropriate torque wrench and manufacturer-specified fasteners to seat the insert securely in the holder. Inspect the seating pocket for chips or debris before installation to ensure proper insert seating and runout control.
