Allied Machine 1C51A-0025 Spade Drill Insert 25/32 in

Product Description

The ALLIED MACHINE AND ENGINEERING 1C51A-0025 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. Part of the T-A series, this insert measures 25/32 inches in diameter with a 132-degree point angle and a 0.1563-inch thickness. The TiAlN coating is applied via PVD process, providing thermal resistance and extended tool life in demanding cutting conditions. This insert fits a Seat Size 1 holder and is manufactured to C5 (P40) grade carbide standards. It is intended for use by machinists and tooling professionals in metal fabrication and production drilling environments.

The 1C51A-0025 is suited for drilling operations in steel and hard materials in both job shop and production settings. The T-A series platform is a modular spade drilling system where the insert is paired with a compatible T-A series holder. Typical applications include through-hole and blind-hole drilling in ferrous metals. The C5 material grade and P and H workpiece material codes confirm suitability for steel and hard material workpieces across a range of hardness levels.
