Allied Machine 433T-0123 Spade Drill Insert 1-23/32 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 433T-0123 is a spade drill insert designed for high-production drilling operations in metalworking applications. Built from M4-grade High Speed Steel and finished with a TiN (titanium nitride) PVD coating, this insert delivers extended tool life and reduced friction at the cutting edge. It measures 1-23/32 inches in diameter, seats in a Size 3 holder, and features a 132-degree point angle suited for accurate entry and controlled chip formation. The GEN2 T-A series design is a proven platform widely used by machinists and toolroom professionals in industrial drilling setups.

This insert is intended for use in drilling steel, cast iron, and non-ferrous metals, covering workpiece material classifications P, K, and N. It fits Size 3 spade drill holders in the GEN2 T-A series. Typical applications include through-hole and blind-hole drilling in production machining environments, job shops, and heavy-industry maintenance settings where consistent hole quality and insert interchangeability are required.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Always power down and lock out the spindle before removing or seating the insert. Confirm the insert is fully seated and the clamping screw is properly torqued per the holder manufacturer specifications before returning the tool to service. Inspect the seat and holder pocket for chips or debris prior to each insert change to prevent seating irregularities and runout.
