Allied Machine 182T-0109 Spade Drill Insert 1-9/32 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 182T-0109 is a cobalt spade drill insert designed for high-performance hole-making in demanding metal-cutting applications. Part of the T-A series, this insert features a 132-degree point angle and a physical vapor deposition (PVD) titanium nitride (TiN) coating that extends tool life and reduces built-up edge. It carries a seat size 2 designation and measures 1-9/32 inches in diameter with a thickness of 0.1875 inches. Machinists and toolroom professionals use this insert in conjunction with T-A spade drill holders for production drilling operations across a wide range of workpiece materials.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It is a common choice in job shops, production machine shops, and industrial manufacturing environments where consistent hole geometry and tool life are critical. The TiN PVD coating provides a hard, low-friction surface layer that helps maintain cutting-edge integrity across extended run cycles. It fits seat size 2 T-A series holders, making it a straightforward drop-in for existing tooling setups that use the T-A spade drill system.

Key Features

• 132-degree point angle optimized for reduced thrust and clean entry on hard and tough materials
• TiN PVD coating extends tool life and reduces friction at the cutting edge
• Compatible with steel, stainless steel, cast iron, super-alloys, titanium, and hard materials
• 0.1875 inch insert thickness fits standard T-A seat size 2 holder pockets

Compatibility

Designed for use with T-A series spade drill holders accepting seat size 2 inserts. Compatible workpiece materials include steel (P), stainless steel (M), cast iron (K), super-alloys and titanium (S), and hard materials (H) per ISO material classification codes.

Installation Notes

Insert installation should be performed by a qualified machinist or toolroom technician. Ensure the holder pocket and seat surfaces are clean and free of chips or debris before seating the insert. Use the correct torque wrench and manufacturer-specified insert screws when securing the insert to the holder body. Always inspect the seating pocket for wear or damage before installing a new insert.
