Allied Machine 1023T-0131 Spade Drill Insert 1-31/32 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 1023T-0131 is a spade drill insert designed for high-productivity drilling in metalworking applications. It measures 1-31/32 inches in diameter and seats in a Series C holder. Manufactured from high speed steel (HSS) with a PVD-applied titanium nitride (TiN) coating, this insert delivers improved wear resistance and extended tool life compared to uncoated HSS inserts. The 130-degree point angle suits general-purpose drilling in steel, cast iron, and non-ferrous metals. Machinists and toolroom professionals install this insert into compatible spade drill bodies for through-hole and blind-hole operations on machining centers, lathes, and drill presses.

This insert is suited for production drilling in ferrous and non-ferrous materials including steel, cast iron, and non-ferrous metals (ISO material codes P, K, and N). The Series C seat designation matches standard Allied Machine Series C spade drill holders. Typical applications include high-volume hole-making where insert replaceability reduces downtime versus regrinding solid drills. The 130-degree point geometry is a general-purpose angle appropriate for a broad range of workpiece materials encountered in job shop and production environments.

Key Features

• 1-31/32 inch diameter for precise bore sizing in Series C holders
• High speed steel construction provides toughness for interrupted cuts and varying workpiece hardness
• TiN coating applied via PVD process improves surface hardness and reduces built-up edge
• 130-degree point angle suits general-purpose drilling across steel, cast iron, and non-ferrous metals
• Replaceable insert design eliminates regrinding and reduces tool change time
• Thickness of 0.3125 inches and height of 1-19/64 inches for consistent seating geometry

Compatibility

Designed for use with Allied Machine and Engineering Series C spade drill holders. Compatible with workpiece materials including steel, cast iron, and non-ferrous metals per ISO codes P, N, and K.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before removing or seating the insert. Ensure the holder seat is clean and free of chips or debris before installing the new insert, as contamination affects runout and cutting performance. Follow the toolholder manufacturer torque specifications for the clamping screw — do not overtighten.
