Allied Machine 152A-33 Spade Drill Insert 33mm Cobalt Tialn

Product Description

The ALLIED MACHINE AND ENGINEERING 152A-33 is a cobalt spade drill insert designed for high-performance hole-making in demanding production environments. Part of the T-A Series, this insert measures 33 mm in diameter and seats in a Size 2 holder. It features a 132-degree point angle and a TiAlN (titanium aluminum nitride) PVD coating that extends tool life by improving heat and wear resistance at elevated cutting speeds. At 0.1875 inches thick and 0.1 pounds, it is a precision-ground replacement insert intended for use in compatible T-A Series spade drill bodies. Installation is performed by qualified machinists or tooling technicians in CNC or manual drilling operations.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, and titanium — covering ISO workpiece material classifications P, M, K, and S. It is a strong fit for production shops, job shops, and maintenance machining operations where consistent hole quality and insert longevity are priorities across a range of ferrous and exotic workpiece materials.
