Allied Machine 4C12P-0112 Spade Drill Insert 1-3/8 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 4C12P-0112 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. It features a 132-degree point angle and an AM300 PVD coating, which provides wear resistance and extended tool life in demanding cutting applications. The insert fits Seat Size 2 holders in the GEN2 T-A spade drill system. At 0.1875 inches thick and 1-3/8 inches in diameter, it is engineered for precise, repeatable hole geometry. This insert is installed and replaced by machinists and toolroom technicians as a consumable component in production or job-shop drilling operations.

This insert is suited for drilling operations in steel and hard workpiece materials, consistent with Primary Workpiece Material Code P and H classifications. It is used in the GEN2 T-A spade drill system, making it applicable to production environments where interchangeable inserts reduce downtime. Typical applications include general metalworking, heavy-duty structural drilling, and component manufacturing where hole diameter consistency at 1-3/8 inches is required. It is used in CNC machining centers, turret lathes, and drill presses equipped with compatible T-A series spade drill holders.

Installation Notes

Installation is performed by a machinist or toolroom technician. Always power down and lock out the machine spindle before removing or seating a spade drill insert. Use the correct torque wrench and insert screws specified for T-A series holders to ensure proper seating. Inspect the holder seat for chips or debris before installing a new insert, as contamination will affect hole accuracy and can damage the holder.
