Allied Machine 4C12P-0108-HE Spade Drill Insert 1-1/4 in

Product Description

The ALLIED MACHINE AND ENGINEERING 4C12P-0108-HE is a solid carbide spade drill insert engineered for high-performance drilling in steel and hard materials. Part of the GEN2 T-A series, this insert features a 132-degree point angle and an AM300 PVD coating that extends tool life in demanding cutting applications. At 1-1/4 inches in diameter with a Seat Size 2 form factor and a 0.1875-inch thickness, it is designed to deliver consistent hole quality and chip control. Machinists and tooling specialists install this insert in compatible T-A spade drill holders on CNC machining centers and manual drilling equipment.

This insert is suited for production drilling in ferrous metals, hardened steels, and other hard workpiece materials classified under material codes P and H. The GEN2 T-A series is a widely used platform in manufacturing environments where through-hole and blind-hole drilling accuracy is required. Typical applications include job shops, aerospace component machining, and general metalworking operations that demand repeatable performance from replaceable insert tooling. The AM300 PVD coating provides thermal resistance and surface hardness appropriate for these cutting conditions.

Key Features

• Solid carbide construction, Manufacturer Grade C1 (K35), for high hardness and wear resistance
• AM300 PVD coating enhances tool life in steel and hard material drilling
• 132-degree point angle for efficient penetration and reduced thrust in ferrous materials
• GEN2 T-A series platform for compatibility with standard T-A spade drill holders
• Seat Size 2 form factor provides secure seating and precise radial location in the holder
• Fractional inch system, 1-1/4 inch diameter, for straightforward size identification

Compatibility

Designed for use with GEN2 T-A series spade drill holders accepting a Seat Size 2 insert at 1-1/4 inch diameter. Confirm holder seat size and diameter range before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before seating or removing the insert. Clean the holder pocket and seating surfaces before installation to ensure proper insert contact and prevent premature wear. Follow the holder manufacturer's torque specifications for the clamping screw, as over- or under-torquing affects insert stability and hole accuracy.
