Allied Machine 1C2ZT-0016 Spade Drill Insert 0.5in Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C2ZT-0016 is a solid carbide spade drill insert designed for high-performance hole-making in demanding industrial and machining applications. Measuring 0.5 inches in diameter with a seat size Z and a 132-degree point angle, this insert seats into compatible T-A series spade drill holders. It carries a TiN (titanium nitride) PVD coating and a C2 (K20) carbide grade, which together provide strong wear resistance and edge retention at elevated cutting speeds. Machinists, CNC operators, and tooling specialists install this insert as part of a modular drill system to achieve accurate, repeatable bore diameters. The insert thickness is 0.0938 inches.

This insert is suited for use on CNC machining centers, lathes, and drill presses where consistent hole quality is required across production runs. Its carbide grade and TiN coating make it well-matched for cutting stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium. These are materials commonly encountered in aerospace, automotive, oil and gas, and general metalworking environments where insert durability directly affects cycle time and part quality.

Key Features

• Solid carbide construction with C2 (K20) grade for high hardness and wear resistance
• TiN PVD coating extends tool life and reduces built-up edge on difficult workpiece materials
• 132-degree point angle suits flat-bottomed and through-hole applications in hard materials
• Seat size Z for use with compatible T-A series spade drill holders
• 0.5-inch cutting diameter with 0.0938-inch insert thickness for precise fitment
• Modular insert design allows blade replacement without changing the drill body

Compatibility

Designed for use with T-A series spade drill holders that accept a seat size Z insert. Verify holder seat size and insert diameter match before installation.

Installation Notes

This insert is installed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Inspect the holder pocket and seating surfaces for debris or damage before installation, as contamination at the seat can affect insert position and hole accuracy. Follow the tool manufacturer's recommended clamping torque procedure for the specific holder model in use.
