Allied Machine 1C50A-.609 Spade Drill Insert 39/64 in

Product Description

The ALLIED MACHINE AND ENGINEERING 1C50A-.609 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. Built to T-A Series specifications with a Seat Size 0 body, this insert features a 132-degree point angle and a PVD-applied TiAlN coating that extends tool life in demanding cutting conditions. At 0.125 inches thick and 39/64 inches in diameter, it is sized for precise fitment in compatible T-A Series spade drill holders. Machinists and toolroom professionals install this insert for production drilling where carbide toughness and coating adhesion matter most.

This insert is suited for use in metalworking applications targeting steel and hard material workpieces, classified under material grades P and H. The T-A Series platform is widely used in production machining environments where replaceable insert tooling reduces downtime versus solid drill replacement. Typical applications include through-hole and blind-hole drilling on CNC machining centers and manual lathes where controlled chip evacuation and consistent point geometry are required.

Key Features

• Solid carbide construction in manufacturer grade C5 (P40) for rigidity and wear resistance in steel cutting
• TiAlN coating applied via PVD process for improved thermal resistance and extended edge life
• 132-degree point angle for reduced thrust and improved penetration in steel and hard materials
• 39/64 inch diameter with 0.125 inch thickness for accurate T-A Series Seat Size 0 holder fitment
• Lightweight at 0.1 pounds — easy to handle and stock in tool crib environments
• Single-piece packaging with a minimum order quantity of one for flexible procurement

Compatibility

Designed for use with T-A Series Seat Size 0 spade drill holders. Verify holder seat size and insert diameter before installation to confirm correct fitment.

Installation Notes

Installation is performed by machinists or toolroom technicians. Before swapping inserts, ensure the machine spindle is fully stopped and all power is isolated per shop lockout/tagout procedures. Seat the insert fully into the holder pocket and torque the clamping screw to the holder manufacturer's specified value using a calibrated torque wrench — do not estimate by feel. Inspect the holder seat for wear or debris before installing a new insert to avoid premature edge failure.
