Allied Machine 4C11P-0024 Spade Drill Insert 3/4 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 4C11P-0024 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. It carries a 3/4 inch diameter, a 132-degree point angle, and a Seat Size 1 designation for use with compatible GEN2 T-A spade drill holders. The insert is finished with an AM300 PVD coating, which reduces friction and extends tool life under demanding cutting conditions. At 0.1 pounds, it is a compact, single-use insert that is replaced at the spindle rather than requiring full tool replacement. Typical users are machinists and tool-and-die professionals working in production or job-shop environments.

This insert is suited for drilling steel and hard material workpieces in CNC machining centers, drill presses, and turning equipment. It is part of the GEN2 T-A series and seats into compatible Allied Machine T-A spade drill bodies at Seat Size 1. The AM300 PVD coating makes it particularly effective in cutting P-category and H-category workpiece materials per ISO material classification. It is appropriate for both production drilling and precision bore applications where replaceable insert tooling is preferred over solid twist drills.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. The machine spindle must be fully de-energized and the tool secured in a vise or holder before seating or removing the insert. Use the appropriate torx or hex key as specified by the holder manufacturer when torquing the insert screw — do not use impact tools on insert hardware. Inspect the seat pocket for chips or debris before installing a new insert to ensure proper seating and runout accuracy.
