Allied Machine 1C2ZT-0015 Spade Drill Insert 15/32 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C2ZT-0015 is a solid carbide spade drill insert designed for high-performance hole-making operations in demanding machining environments. This insert belongs to the T-A series and features a 132-degree point angle with a TiN (titanium nitride) PVD coating for extended tool life and reduced friction. It carries a C2 (K20) manufacturer grade, making it well-suited for applications requiring consistent cutting performance across a range of workpiece materials. Machinist and toolroom professionals install this insert into compatible T-A series spade drill holders as a direct replacement when edges are worn.

This insert is sized at 15/32 inches in diameter with a Seat Size Z designation for holder fitment. It is rated for use on stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium. These material categories correspond to ISO workpiece codes M, K, N, and S. Typical applications include production drilling in CNC machining centers, turret lathes, and mill-drill setups where replaceable insert tooling reduces overall cost per hole versus solid drill replacement.

Key Features

• Solid carbide construction at C2 (K20) material grade for rigidity and wear resistance
• TiN PVD coating reduces friction and extends insert service life
• 132-degree point angle suited for through-hole and blind-hole drilling
• Seat Size Z for direct fitment into compatible T-A series spade drill holders
• Rated for stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium
• Thickness of 0.0938 inches for precise seating and repeatable positioning

Compatibility

Designed for use with T-A series spade drill holders accepting a Seat Size Z insert at 15/32 inches diameter. Confirm holder seat size and series designation before installation to ensure proper fitment.

Installation Notes

Insert replacement should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per applicable shop safety procedures. Use the correct insert mounting screw and torque driver specified by the holder manufacturer — do not substitute hardware. Inspect the holder seat for chips or damage before seating the new insert, as debris under the insert will affect drill runout and hole quality.
