Allied Machine 1C52T-0102 Spade Drill Insert 1-1/16 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C52T-0102 is a solid carbide spade drill insert designed for high-performance hole-making in steel and hard materials. Part of the T-A series, this insert features a 132-degree point angle and a TiN (titanium nitride) PVD coating that extends tool life by reducing friction and wear at the cutting edge. At 1-1/16 inches in diameter with a Seat Size 2 designation, it fits directly into compatible T-A series spade drill holders. It is typically installed by machinists and tooling technicians in production drilling operations on CNC machining centers, manual lathes, and drill presses.

This insert is suited for drilling into steel and hard materials in both job-shop and production environments. The T-A series platform is a modular indexable spade drill system that allows the insert to be replaced independently of the holder, reducing tooling cost per hole. Typical applications include through-hole and blind-hole drilling in structural steel, alloy steel, and similarly rated workpiece materials classified under ISO material grade P and H. It is sold individually, making it a practical replacement option for worn or chipped inserts already in service.

Key Features

• Solid carbide construction at manufacturer grade C5 (P40) for strength and wear resistance in steel applications
• TiN PVD coating reduces cutting friction and extends insert service life
• 132-degree point angle optimized for entry and centering in steel and hard materials
• Seat Size 2 designation for direct fit into compatible T-A series spade drill holders
• 1-1/16 inch diameter at 0.1875 inch thickness for consistent hole geometry
• Modular indexable design allows insert-only replacement without discarding the holder

Compatibility

Designed for use with T-A series spade drill holders that accept a Seat Size 2 insert at 1-1/16 inch diameter. Primary workpiece materials are steel and hard materials, corresponding to ISO material codes P and H.

Installation Notes

Installation is performed by tooling technicians or machinists. Power down and lock out the machine spindle before seating or removing the insert. Ensure the holder seat is clean and free of chips or debris before placing the insert, as contamination at the seating surface can cause runout and premature failure. Follow the holder manufacturer torque guidelines for the clamping screw — do not over-tighten, as this can crack carbide inserts.
