Allied Machine 182T-0108 Spade Drill Insert 1-1/4 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 182T-0108 is a cobalt spade drill insert designed for high-performance hole-making in demanding metalworking applications. Part of the T-A series, this insert measures 1-1/4 inches in diameter and fits a Seat Size 2 holder. The 132-degree point angle provides aggressive cutting geometry suited to hard and abrasive workpiece materials. A TiN (titanium nitride) PVD coating extends tool life by reducing friction and improving wear resistance at the cutting edge. At 0.1875 inches thick, the insert is built for rigidity under load. Licensed machinists and CNC operators working in job shops, production facilities, and maintenance environments are the primary users of this tooling.

This insert is engineered for drilling into steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It is well suited to applications where a replaceable insert system reduces downtime compared to regrinding solid drills. The T-A series indexable spade drill system allows the insert to be swapped quickly without removing the holder from the spindle, making it a practical choice for high-volume production runs and intermittent heavy-duty drilling alike.

Key Features

• 1-1/4 inch diameter with Seat Size 2 for T-A series holders
• 132-degree point angle for positive engagement on steel and hard materials
• Cobalt substrate for heat and wear resistance in difficult-to-machine alloys
• TiN PVD coating reduces friction and extends insert service life
• 0.1875 inch insert thickness provides rigidity under axial drilling loads
• Fractional inch system sizing for compatibility with standard T-A toolholders

Compatibility

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

Installation Notes

Insert seating and torqueing should be performed by a qualified machinist or toolroom technician following the toolholder manufacturer's insert-clamping procedure. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing inserts. Inspect the holder seat for chips or damage before seating a new insert, as debris under the insert can cause premature failure or poor hole geometry. Follow applicable shop safety protocols and machine tool manufacturer guidelines when setting up spade drill assemblies.
