Allied Machine 1021T-0110 Spade Drill Insert 1-5/16 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 1021T-0110 is a spade drill insert designed for high-production hole-making in a range of metalworking applications. It measures 1-5/16 inches in diameter with a 7/8-inch height and a 0.1875-inch thickness. The insert is manufactured from high speed steel and features a titanium nitride (TiN) PVD coating that increases surface hardness and reduces friction at the cutting edge. The 130-degree point angle suits general-purpose drilling in steel, cast iron, and non-ferrous metals. This insert seats in a Series A holder and is sold individually as a single-piece package quantity.

This insert is suited for use in CNC machining centers, drill presses, and other powered drilling equipment where replaceable spade inserts are preferred over solid drills. Its compatibility with Series A seat-size holders makes it a practical choice for shops that have standardized on that tooling platform. Typical applications include through-hole and blind-hole drilling in steel structures, cast iron housings, and non-ferrous components across industrial manufacturing environments. A licensed machinist or tooling technician is the expected installer and operator.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with spade drill systems. Ensure the machine spindle is fully stopped and the tool holder is secured in a vise or fixture before seating or removing the insert. Inspect the holder seat for debris or damage before installing a new insert, and verify that all fastening hardware is torqued according to the holder manufacturer specifications. Follow applicable shop safety standards and machine guarding requirements during setup and operation.
