Allied Machine 1021T-0101 Spade Drill Insert 1-1/32 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 1021T-0101 is a spade drill insert designed for high-productivity hole-making operations in metal fabrication and machining environments. It features a 1-1/32 inch cutting diameter, a 130-degree point angle, and is manufactured from high speed steel (HSS) with a TiN (titanium nitride) PVD coating applied to improve wear resistance and extend tool life. The insert seats into a Series A holder and measures 7/8 inch in height with a thickness of 0.1875 inches. This insert is installed by machinists and toolroom technicians working on CNC machining centers, drill presses, and manual lathes.

This spade drill insert is suited for drilling operations in steel, cast iron, and non-ferrous metals, covering ISO workpiece material classifications P, K, and N. Typical applications include production drilling of through-holes and blind holes in structural components, flanges, and general machined parts in industrial and manufacturing settings. The TiN PVD coating allows for increased cutting speeds compared to uncoated HSS tooling, making it a practical option for shops seeking extended insert life without moving to carbide grades.

Key Features

• 1-1/32 inch cutting diameter for precise hole sizing in Series A spade drill bodies
• 130-degree point angle reduces thrust and improves chip formation on entry
• High speed steel construction provides toughness in interrupted cuts and variable-feed applications
• TiN PVD coating improves surface hardness and reduces built-up edge on the cutting face
• Compatible with steel, cast iron, and non-ferrous metal workpieces (ISO P, K, N classifications)
• Height of 7/8 inch and thickness of 0.1875 inches for correct seating in Series A holders

Compatibility

Designed for use with Series A spade drill holders accepting a 1-1/32 inch diameter insert. Compatible with workpiece materials classified as steel (P), cast iron (K), and non-ferrous metals (N).

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before seating or removing the insert. Ensure the insert seat and clamping surfaces are clean and free of chips before securing the insert. Follow the toolholder manufacturer torque and clamping specifications when fastening the insert screw.
