Allied Machine 4C11P-0030 Spade Drill Insert 15/16 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 4C11P-0030 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 carries the AM300 PVD coating, which extends tool life in demanding cutting applications. The insert seats in a Size 1 holder and belongs to the GEN2 T-A series, a platform widely used in production drilling environments. At 0.1563 inches thick and 15/16 inch in diameter, this insert delivers consistent hole geometry when run at appropriate feed and speed parameters. It is installed and used by machinists, toolroom technicians, and CNC operators working in metal fabrication and production machining.

This insert is suited for drilling operations in steel and hard workpiece materials in both job shop and production environments. The GEN2 T-A platform is a common choice for through-coolant spade drilling on CNC machining centers and lathes. The AM300 coating provides wear resistance when cutting ferrous materials classified under material grades P and H. Typical applications include structural steel drilling, tooling fabrication, and general-purpose metalworking where consistent hole sizing and insert longevity are priorities.

Key Features

• Solid carbide construction at manufacturer grade C1 (K35) for rigidity and wear resistance
• AM300 PVD coating extends cutting life in steel and hard material applications
• 132-degree point angle suits general-purpose drilling in ferrous workpiece materials
• GEN2 T-A series design for use with compatible Size 1 spade drill holders
• 15/16 inch diameter provides precise hole sizing in production drilling setups

Compatibility

Designed for use with Size 1 GEN2 T-A series spade drill holders. Compatible primary workpiece materials include steel and hard materials (material grades P and H).

Installation Notes

This insert is seated and secured by a machinist or CNC operator into a compatible spade drill holder body. Always ensure the machine spindle is fully stopped and locked out before changing inserts. Inspect the holder seat for chips or damage before seating the new insert, as debris on the seat surface will affect hole accuracy and can fracture the insert. Follow the holder manufacturer torque recommendations for the insert clamping screw.
