Allied Machine 1C50A-0022 Spade Drill Insert 11/16 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C50A-0022 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. Part of the T-A Series, this insert features a 132-degree point angle and a TiAlN (Titanium Aluminum Nitride) coating applied via PVD process, which improves heat resistance and extends tool life under demanding cutting conditions. The insert measures 0.125 inches in thickness and fits a Seat Size 0 spade drill holder. Machinists and tooling specialists install this insert in compatible T-A Series spade drill bodies for production drilling applications where tool life and hole quality are priorities.

This insert is suited for drilling steel and hard materials in both production and job-shop environments. The T-A Series system uses a replaceable insert design, allowing worn inserts to be swapped out without replacing the entire drill body. Typical applications include through-hole and blind-hole drilling in structural steel, alloy steel, and similarly classified workpiece materials rated under ISO material groups P and H. This is a single-insert package intended for professional machining operations.

Key Features

• Solid carbide construction at manufacturer grade C5 (P40) for rigidity and wear resistance in steel cutting
• TiAlN PVD coating improves surface hardness and thermal stability at elevated cutting speeds
• 132-degree point angle optimized for flat-bottom entry characteristics and reduced thrust
• Seat Size 0 designation for direct compatibility with matching T-A Series spade drill holders
• 0.125 inch insert thickness provides consistent seating and repeatable positioning in the holder
• Replaceable insert design reduces tooling cost per hole compared to solid drill replacement

Compatibility

Designed for use with T-A Series Seat Size 0 spade drill holders. Primary workpiece materials are steel and hard materials classified under ISO material codes P and H.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully stopped and the machine locked out. Seat the insert firmly against the holder pocket and torque the clamping screw according to the tool holder manufacturer specifications before cutting. Inspect the insert seat for chips or contamination before each installation, as debris in the pocket will affect insert positioning and hole quality. Do not use a damaged or chipped insert, as carbide inserts can fracture under load if the cutting edge is compromised.
