Allied Machine 1021T-0100 Spade Drill Insert 1in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 1021T-0100 is a spade drill insert designed for high-production hole-making operations in metalworking applications. Built from high speed steel (HSS) with a physical vapor deposition (PVD) titanium nitride (TiN) coating, this insert delivers improved wear resistance and extended tool life compared to uncoated HSS tooling. At 1 inch in diameter with a 130-degree point angle, it is suited for drilling into steel, cast iron, and non-ferrous metals. Machinists and tool and die professionals install these inserts into compatible spade drill holders on CNC machining centers, lathes, and drill presses.

This insert is intended for use in Series A spade drill holders and is appropriate for both roughing and production drilling in a range of workpiece materials including steel, cast iron, and non-ferrous metals. The 130-degree point angle provides a good balance between centering ability and cutting force distribution, making it a practical choice for general-purpose drilling in machine shops and manufacturing environments. Package quantity is one insert per unit.

Key Features

• 1 inch diameter with a 130-degree point angle for general-purpose hole-making
• High speed steel construction provides toughness in interrupted cuts and varied feed conditions
• TiN coating applied via PVD process for increased surface hardness and reduced friction

• Rated for use in steel, cast iron, and non-ferrous metal workpiece materials (ISO material codes P, K, N)
• 0.1875 inch thickness and 7/8 inch height for consistent seating and repeatability

Compatibility

Designed for use with Series A spade drill holders. Compatible workpiece materials include steel, cast iron, and non-ferrous metals as indicated by ISO codes P, K, and N.

Installation Notes

Insert installation should be performed by a qualified machinist with the spindle fully powered down and locked out. Seat the insert flush against the holder pocket and secure with the appropriate fastener torqued to the holder manufacturer specification. Inspect the insert seat and holder pocket for chips or debris before seating to prevent rocking or premature insert failure. Follow your facility safety procedures and applicable OSHA machine guarding requirements when working on cutting tool assemblies.
