Allied Machine 4C12P-0107 Spade Drill Insert 1-7/32 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 4C12P-0107 is a spade drill insert designed for high-penetration drilling in steel and hard materials. It features a 1-7/32 inch diameter, a 132-degree point angle, and a C1 (K35) carbide grade body finished with an AM300 PVD coating. The AM300 coating is engineered to reduce heat buildup and extend edge life in demanding ferrous and hard-material applications. This insert fits Seat Size 2 holders in the GEN2 T-A spade drill system. It is installed by machinists and tool-and-die professionals working in production drilling operations where indexable tooling is standard practice.

This insert is suited for drilling operations in steel and hard material workpieces, including production environments running CNC machining centers, lathes with live tooling, and dedicated drill presses. The GEN2 T-A platform is a common choice in high-volume metal fabrication and industrial manufacturing settings where consistent hole geometry and repeatable tool life are required. The fractional inch sizing at 1-7/32 inches makes this insert appropriate for applications specifying that bore diameter without metric conversion.

Key Features

• 1-7/32 inch cutting diameter for precise fractional-inch bore sizing
• 132-degree point angle optimized for penetration in steel and hard materials
• C1 (K35) carbide grade provides hardness and wear resistance in ferrous applications
• AM300 PVD coating reduces thermal load and improves edge longevity
• Fits Seat Size 2 holders in the GEN2 T-A spade drill system
• Fractional inch measurement system for direct compatibility with inch-standard tooling setups

Compatibility

Designed for use with Seat Size 2 holders in the Allied Machine and Engineering GEN2 T-A spade drill system. Primary workpiece materials are steel and hard materials (Material Codes P and H).

Installation Notes

Installation is performed by a machinist or tooling technician. Before indexing or replacing the insert, ensure the machine is fully powered down and locked out per OSHA lockout/tagout procedures. Use the correct torque driver for the insert screw to avoid seat damage — refer to the Allied Machine GEN2 T-A holder documentation for the specified fastener procedure. Inspect the holder seat for chips or wear before seating the new insert.
