Allied Machine 1022T-0108 Spade Drill Insert 1-1/4 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 1022T-0108 is a spade drill insert designed for high-performance hole-making operations in a range of workpiece materials. It measures 1-1/4 inches in diameter with a Seat Size B designation and is manufactured from High Speed Steel with a TiN (titanium nitride) PVD coating that extends tool life and reduces friction at the cutting edge. The 130-degree point angle makes it well-suited for drilling into flat or curved surfaces with controlled entry. Machinists and tooling technicians install this insert into compatible spade drill holders as a replaceable cutting element.

This insert is intended for use in production drilling applications where repeatable hole geometry and material removal rate are priorities. It is rated for use in steel, cast iron, and non-ferrous metals, covering a broad range of common shop materials. Typical applications include component manufacturing environments where through-holes or blind holes of 1-1/4 inches are machined on CNC lathes, machining centers, or drill presses equipped with the appropriate Seat Size B spade drill body.

Key Features

• 1-1/4 inches cutting diameter with Seat Size B seating for direct body compatibility
• High Speed Steel construction provides toughness and resistance to shock loading
• TiN PVD coating reduces wear and lowers cutting friction for extended insert life
• 130-degree point angle supports stable, controlled entry across flat and curved surfaces
• Rated for steel (P), cast iron (K), and non-ferrous metals (N) per ISO workpiece material codes
• Thickness of 0.2813 inches ensures consistent seating and repeatable cutting geometry

Compatibility

Designed for use with Seat Size B spade drill holders that accept 1-1/4 inch diameter inserts. Compatible workpiece materials include steel, cast iron, and non-ferrous metals as designated by ISO material codes P, K, and N.

Installation Notes

Installation is performed by a machinist or tooling technician. The machine spindle must be fully stopped and the tool holder secured in a vise or tool block before seating or removing the insert. Use the manufacturer-recommended torx or hex key to fasten the insert clamp screw; do not overtighten by improvised means. Inspect the holder seat for chips or damage before installing a new insert to ensure proper seating and cutting accuracy.
