Allied Machine 1021T-0111 Spade Drill Insert 1-11/32 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 1021T-0111 is a high speed steel spade drill insert designed for deep-hole and high-production drilling operations. It features a 1-11/32 inch cutting diameter, a 130-degree point angle optimized for fast penetration and accurate entry, and a TiN (titanium nitride) PVD coating that extends cutting edge life by reducing friction and heat buildup. The insert seats in a Series A holder, measures 7/8 inch in height and 0.1875 inches in thickness. Machinists and tool-room technicians install this insert as a replaceable cutting element in compatible spade drill bodies used on CNC machining centers, lathes, and drill presses.

This insert is suited for drilling steel, cast iron, and non-ferrous metals across a range of industrial and job-shop applications. It performs well in both roughing and production drilling scenarios where insert interchangeability and quick tool changes are priorities. The TiN coating and HSS substrate make it appropriate for moderate cutting speeds on workpiece materials classified under ISO P, K, and N material groups. Typical applications include through-holes and blind holes in structural steel components, gray iron castings, and aluminum workpieces.

Key Features

• 1-11/32 inch cutting diameter for mid-range hole sizes
• 130-degree point angle for reduced thrust and accurate spotting
• High speed steel substrate provides toughness and re-sharpenability
• TiN PVD coating reduces friction and extends insert service life
• Series A seat size for compatibility with standard A-series spade drill holders
• Compact 7/8 inch height and 0.1875 inch thickness for secure seating

Compatibility

Designed for use with Series A spade drill bodies that accept standard A-seat inserts. Compatible with workpiece materials including steel, cast iron, and non-ferrous metals (ISO material groups P, K, and N).

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before torquing the retention hardware. Follow the drill body manufacturer's seating procedure to avoid insert movement or premature edge failure during cutting.
