Allied Machine 4C2ZP-0016 Spade Drill Insert 1/2 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 4C2ZP-0016 is a solid carbide spade drill insert designed for use in GEN2 T-A modular spade drilling systems. Built to Seat Size Z and measuring 0.500 inches in diameter, this insert features a 132-degree point angle and an AM300 PVD coating. The AM300 coating improves wear resistance and edge stability when drilling through demanding workpiece materials. Manufactured to C2 (K20) carbide grade, it delivers consistent cutting performance in production and job-shop environments. Installation is performed by machinists and tooling technicians working with compatible T-A spade drill holders.

This insert is suited for drilling stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium. The 132-degree point angle supports controlled entry and reduced thrust in these materials. Typical applications include production drilling on CNC machining centers and manual mills where a replaceable insert system is preferred over solid carbide or indexable drill bodies. The GEN2 T-A platform is a common choice in high-volume drilling operations where insert changeover speed and dimensional repeatability are priorities.

Key Features

• 0.500 inch cutting diameter with Seat Size Z for GEN2 T-A holder compatibility
• Solid carbide construction at C2 (K20) material grade for hardness and wear resistance
• AM300 PVD coating for improved performance in stainless steel, cast iron, non-ferrous metals, and super-alloys
• 132-degree point angle reduces thrust and improves entry geometry in tough materials
• Replaceable insert design minimizes downtime compared to full drill replacement

Compatibility

Designed for use with GEN2 T-A spade drill holders accepting Seat Size Z inserts. Suitable for drilling stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium. Verify holder seat size and insert diameter before installation.

Installation Notes

Insert seating and torquing should be performed by a qualified machinist or tooling technician following the holder manufacturer specifications. Power down and lock out the spindle before changing inserts. Inspect the holder seat for chips, burrs, or wear before seating the new insert. Do not force the insert into the seat, as improper seating can cause insert failure or workpiece damage.
