Allied Machine 1023T-0125 Spade Drill Insert 1-25/32 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 1023T-0125 is a spade drill insert designed for high-production drilling operations in metal fabrication and machining environments. Built from high speed steel (HSS) with a physical vapor deposition (PVD) titanium nitride (TiN) coating, this insert delivers extended tool life and improved wear resistance compared to uncoated HSS tooling. The 130-degree point angle suits flat-bottom entry and general-purpose drilling. At 1-25/32 inches in diameter and a Series C seat size, it fits directly into compatible C-series spade drill holders. Machining professionals install this insert as a replaceable cutting element, making it a cost-effective solution for high-volume hole-making.

This insert is suited for drilling steel, cast iron, and non-ferrous metals, covering ISO material categories P, N, and K. Typical applications include production drilling in job shops, contract machining facilities, and maintenance repair operations where consistent hole quality and repeatable tool changes are required. The Series C designation matches a specific holder shank size, so confirming holder compatibility before ordering is essential. This insert is sold individually and is intended for use in CNC machining centers, drill presses, and manual boring mills.

Key Features

• 1-25/32 inch diameter cutting edge for consistent, repeatable hole sizing
• High speed steel construction provides toughness for interrupted cuts and varied material hardness
• TiN PVD coating reduces friction and extends cutting edge life compared to bare HSS
• 130-degree point angle supports general-purpose drilling and clean entry geometry
• Series C seat size for direct fit into compatible C-series spade drill holders
• Rated for steel, cast iron, and non-ferrous metal workpiece materials

Compatibility

Designed for use with Series C spade drill holders. Compatible primary workpiece materials include steel (ISO P), cast iron (ISO K), and non-ferrous metals (ISO N). Confirm holder series and seat size match before installation.

Installation Notes

Installation is performed by a machinist or toolroom technician. The machine spindle must be fully stopped and the machine locked out before inserting or removing the drill insert. Seat surfaces on the holder should be inspected and cleaned of chips or debris before seating the insert to ensure proper support and accurate positioning. Follow the holder manufacturer's torque and clamping specifications for the insert screw.
