Allied Machine 1C50T-0018 Spade Drill Insert 9/16 in 132 Deg

Product Description

The ALLIED MACHINE AND ENGINEERING 1C50T-0018 is a 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 Physical Vapor Deposition (PVD) titanium nitride (TiN) coating for extended tool life and reduced friction at the cutting edge. At 0.125 inches thick and 9/16 inches in diameter, the insert fits Seat Size 0 spade drill holders. It is intended for use by machinists and tooling professionals in production drilling applications where precision and tool durability are critical.

This insert is suited for drilling operations in steel and hard material workpieces in both job shop and production environments. The T-A series is a common platform in metalworking operations that require interchangeable spade drill inserts across a range of holder sizes. The C5 (P40) carbide grade targets medium to heavy interrupted and continuous cuts in steel. Typical installations include CNC machining centers, lathes with live tooling, and manual drill presses where spade drill holders are already in use.

Key Features

• 9/16 inch diameter with Seat Size 0 for direct holder compatibility in the T-A series platform
• 132-degree point angle optimized for steel and hard material entry without excessive thrust
• C5 (P40) carbide grade provides toughness for medium to heavy cutting conditions
• TiN PVD coating reduces heat buildup and extends edge life in ferrous materials
• 0.125 inch insert thickness for consistent seating and repeatable depth performance
• Fractional inch measurement system for straightforward integration with standard US tooling setups

Compatibility

Designed for use with T-A series spade drill holders accepting Seat Size 0 inserts. Primary workpiece materials are steel and hard materials (Material Grade C5, Codes P and H). Confirm holder seat size and series designation before installation.

Installation Notes

Spade drill inserts are installed and serviced by qualified machinists or tooling technicians. Always power down and lock out the machine before removing or seating an insert. Ensure the holder seat is clean and free of chips or debris before inserting to achieve proper seating and prevent insert rocking. Do not exceed the manufacturer-recommended feed and speed parameters for the workpiece material and holder size.
