Allied Machine 1C50T-0020 Spade Drill Insert 5/8 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C50T-0020 is a solid carbide spade drill insert designed for precision hole-making in demanding machining applications. Built to T-A series specifications with a Seat Size 0 designation, this insert features a 132-degree point angle and a TiN (titanium nitride) PVD coating that extends cutting tool life by reducing friction and heat buildup at the cutting edge. At 0.125 inches thick and 5/8 inch in diameter, it is suited for drilling operations where dimensional accuracy and surface finish are critical. Licensed machinists and tool-and-die professionals are the primary installers of this insert.

This insert is intended for use in steel and hard materials, classified under workpiece material grades P and H. It is a T-A series replacement-style insert compatible with Seat Size 0 T-A series spade drill holders. Typical applications include production drilling in job shops, manufacturing facilities, and aerospace or industrial machining environments where repeatable, high-tolerance bore quality is required in ferrous and hard-material workpieces.

Key Features

• Solid carbide construction rated to manufacturer grade C5 (P40) for use in steel and hard materials
• TiN PVD coating reduces cutting-edge wear and extends insert service intervals
• 132-degree point angle optimized for controlled penetration and chip formation in ferrous materials
• T-A series Seat Size 0 designation ensures drop-in compatibility with matching holder bodies
• 0.125 inch insert thickness provides rigidity under high-feed drilling conditions
• Single-unit packaging allows for precise inventory management and per-insert tracking

Compatibility

Designed for use with T-A series spade drill holder bodies accepting Seat Size 0 inserts. Intended for drilling steel and hard materials (workpiece material grades P and H).

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per applicable safety protocols. Seat surfaces on the holder body should be inspected and cleaned before seating the insert to ensure proper contact and prevent premature wear. Use the correct torque wrench and manufacturer-specified fasteners when securing the insert to the holder body. Do not exceed the holder body's rated speed or feed parameters for the given material and insert diameter.
