Allied Machine 152A-0106 Spade Drill Insert 1-3/16 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 152A-0106 is a cobalt spade drill insert designed for high-performance drilling in demanding metal-cutting applications. Part of the T-A Series, this insert features a 132-degree point angle and a TiAlN (titanium aluminum nitride) PVD coating that extends tool life by reducing heat buildup and improving wear resistance at the cutting edge. At 0.1875 inches thick and sized for a Seat Size 2 holder, it installs directly into compatible T-A Series spade drill bodies. Licensed machinists and tooling technicians working in production or job-shop environments are the primary users of this insert.

This insert is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, and titanium. It is well matched to applications where consistent hole quality and tool life are priorities, including aerospace, energy, and general machining. The 1-3/16 inch cutting diameter makes it a common choice for medium-to-large diameter through-hole and blind-hole drilling on CNC machining centers, lathes with live tooling, and drill presses with adequate spindle rigidity.

Key Features

• 1-3/16 inch cutting diameter in a Seat Size 2 T-A Series insert format
• Cobalt substrate provides toughness and heat resistance in interrupted cuts
• TiAlN PVD coating reduces friction and extends edge life in steel and stainless steel
• 132-degree point angle promotes self-centering and reduces thrust load on entry
• 0.1875 inch insert thickness matches T-A Series Seat Size 2 holder geometry
• Rated for steel, stainless steel, cast iron, super-alloys, and titanium workpiece materials

Compatibility

Designed for use with T-A Series Seat Size 2 spade drill holders. Suitable for workpiece materials classified as P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium) per ISO material group designations.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill body and machine spindle are fully powered down and locked out before seating or removing the insert. Confirm the holder seat and insert seating surfaces are clean and free of chips before torquing the clamping screw. Follow the tool manufacturer's recommended clamping torque specifications for the T-A Series Seat Size 2 holder to prevent insert movement or damage during operation.
