Allied Machine 182T-35 Spade Drill Insert 35mm Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 182T-35 is a spade drill insert designed for use in T-A series spade drill holders. It features a 35 mm cutting diameter, a 132-degree point angle, and is manufactured from cobalt high-speed steel with a TiN (titanium nitride) PVD coating. The cobalt substrate provides heat and wear resistance during high-feed drilling operations, while the TiN coating reduces friction and extends cutting life. At 0.1875 inches thick, this insert seats into a Seat Size 2 holder. It is installed and used by machinists and tool-and-die professionals in production drilling environments.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It fits T-A series Seat Size 2 spade drill holders and is a direct replacement or spare insert for those holders in production machining, job shop, and maintenance environments. Typical applications include through-hole and blind-hole drilling in ferrous and exotic alloy workpieces where insert changeability reduces downtime versus brazed-tip tooling.

Installation Notes

Installation is performed by machinists using the holder manufacturer's recommended insert screw and torque procedure — do not overtighten or substitute non-OEM fasteners. Ensure the holder seat is clean and free of chips or debris before seating the insert. Inspect the seating pocket for wear or damage that could affect insert runout. Follow all machine lockout and spindle-stop procedures before changing inserts.
