Allied Machine 182T-0104 Spade Drill Insert 1-1/8 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 182T-0104 is a cobalt spade drill insert designed for high-performance hole drilling in demanding industrial machining applications. Part of the T-A series, this insert measures 1-1/8 inches in diameter and features a 132-degree point angle for aggressive cutting geometry. The PVD-applied TiN coating improves wear resistance and extends tool life in production environments. At 0.1875 inches thick and 0.1 pounds, it fits standard Seat Size 2 T-A series spade drill bodies. Licensed machinists and tool-room technicians are the primary installers and users of this insert.

This insert is suited for drilling operations in ferrous and non-ferrous materials across a broad range of industrial settings, including general machining, job shops, aerospace component production, and heavy manufacturing. The cobalt substrate combined with the TiN coating makes it effective in applications where heat generation and abrasion are primary concerns. It is appropriate for use in CNC machining centers, manual lathes, and dedicated drilling machines wherever a Seat Size 2 T-A series spade drill body is in service.

Key Features

• 1-1/8 inch diameter with 132-degree point angle for efficient chip formation and entry geometry
• Cobalt insert material provides elevated heat and wear resistance compared to standard high-speed steel
• TiN coating applied via PVD process improves surface hardness and reduces friction during cutting
• Seat Size 2 designation for direct compatibility with T-A series spade drill holders
• 0.1875 inch insert thickness for consistent seating and stable cutting performance
• Rated for use in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials

Compatibility

Designed for use with Seat Size 2 T-A series spade drill bodies. Compatible primary workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials per ISO material codes P, M, K, S, and H.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The drill body must be fully de-energized and the machine spindle locked or at zero RPM before seating or removing the insert. Use the correct torx or hex key specified by the drill body manufacturer to secure the insert clamp screw — do not over-torque. Inspect the insert seat for chips or debris before installation to ensure proper seating and runout.
