Allied 1C5ZA-.484 Spade Drill Insert 31/64 in Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C5ZA-.484 is a solid carbide spade drill insert designed for precision hole-making in steel and hard materials. It features a 132-degree point angle and a TiAlN (titanium aluminum nitride) PVD coating that extends tool life by reducing heat buildup and wear at the cutting edge. The insert fits Seat Size Z holders in the T-A series system, providing a secure, repeatable seating interface. At 0.0938 inches thick and manufactured to a C5 (P40) carbide grade, this insert is built for consistent performance in demanding production and machining environments. Installation and tool changes are handled by machinists and tooling technicians.

This insert is sized at 31/64 inches in diameter and is intended for use in T-A series spade drill holders with a Seat Size Z. It is suited for drilling steel and hard materials in both production shop and job shop settings. The TiAlN coating makes it a practical choice for dry or minimal-lubrication cutting applications where heat resistance is a priority. It is sold individually, making it a direct single-insert replacement or trial option for existing T-A tooling setups.

Key Features

• 31/64 inch diameter with a 132-degree point angle for accurate hole entry and chip control
• Solid carbide construction at C5 (P40) material grade for rigidity and wear resistance
• TiAlN PVD coating improves heat resistance and extends cutting life in steel and hard materials
• Seat Size Z interface ensures proper fit in compatible T-A series spade drill holders
• 0.0938 inch insert thickness provides consistent seating depth across holder bodies
• Sold individually, minimizing overstocking when replacing single worn inserts

Compatibility

Designed for use with T-A series spade drill holders accepting a Seat Size Z insert. Primary workpiece materials are steel and hard materials, corresponding to material codes P and H.

Installation Notes

Spade drill insert changes should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle locked. Clean the insert seat thoroughly before installing to ensure proper seating and runout control. Use the manufacturer-recommended torque driver or wrench for the clamping screw — do not over-torque or use improvised tools. Inspect the seat and clamping components for wear or damage each time an insert is replaced.
