Allied Machine 152N-0102 Spade Drill Insert Cobalt Ticn

Product Description

The ALLIED MACHINE AND ENGINEERING 152N-0102 is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. Part of the T-A Series, this insert features a 132-degree point angle and a TiCN (titanium carbonitride) PVD coating that improves surface hardness and wear resistance. At 0.1875 inches thick and sized for a Seat Size 2 holder, it delivers consistent cutting geometry on 1-1/16 inch diameter bores. Machinists and tool-room technicians working on CNC lathes, machining centers, and drill presses select this insert for its balance of edge retention and thermal stability under load.

This insert is suited for production drilling in steel, stainless steel, cast iron, super-alloys, and titanium — material categories P, M, K, and S in the ISO classification system. It fits into standard T-A Series Seat Size 2 spade drill holders and is appropriate for both roughing and finish-entry drilling cycles in job shop and production environments. It is sold and packaged as a single insert.

Key Features

• 1-1/16 inch cutting diameter in T-A Series Seat Size 2 format
• Cobalt substrate provides toughness and elevated heat resistance over standard HSS
• TiCN PVD coating extends tool life in abrasive and work-hardening materials
• 132-degree point angle reduces thrust force and improves chip formation on entry
• 0.1875 inch insert thickness ensures secure seating and repeatable geometry
• Compatible with ISO material groups P, M, K, and S workpiece materials

Compatibility

Designed for use with T-A Series Seat Size 2 spade drill holders. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, and titanium (ISO classifications P, M, K, and S).

Installation Notes

Installation is performed by a machinist or tool-room technician. Power down and lock out the machine spindle before changing or seating the insert. Ensure the holder pocket and insert seat are clean and free of chips before installation, as debris under the insert will cause premature edge failure or holder damage. Follow the holder manufacturer's torque specification for the clamping screw — do not overtighten.
