Allied 4C20P-0022 Spade Drill Insert 11/16 in Carbide GEN2 T-a

Product Description

The ALLIED MACHINE AND ENGINEERING 4C20P-0022 is a solid carbide spade drill insert designed for high-performance hole making in demanding machining applications. Built to Seat Size 0 within the GEN2 T-A system, it measures 11/16 inches in diameter with a 132-degree point angle and a thickness of 0.125 inches. The insert carries an AM300 PVD coating and is rated to the C2 (K20) material grade, delivering wear resistance and edge retention at elevated cutting speeds. Machinists and tool-and-die professionals install this insert into compatible GEN2 T-A spade drill bodies as a replaceable cutting element.

This insert is suited for production drilling in materials that include stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium. Its AM300 PVD coating provides thermal and oxidation resistance, making it appropriate for interrupted cuts and applications where coolant delivery through the holder is standard practice. The 132-degree point geometry promotes self-centering entry and reduces thrust load in harder workpiece materials. It is sold individually and is a direct replacement element within the GEN2 T-A modular spade drill platform.

Installation Notes

Installation is performed by a machinist or toolroom technician. The spindle must be locked out and all machine power removed before seating or removing the insert. Use the manufacturer-specified torx or hex key to secure the insert screw to the holder; never substitute fastener sizes. Verify insert seating and screw engagement before returning the tool to service.
