Allied Machine 1C52A-25 Spade Drill Insert 63/64 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C52A-25 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) PVD coating that improves wear resistance and heat tolerance at the cutting edge. The insert measures 0.1875 inches thick and seats into a Size 2 holder. Manufactured to C5 (P40) grade carbide, it is suited for aggressive metal removal rates in production drilling environments. Machinists and toolroom technicians install this insert as a replaceable cutting element in compatible T-A Series spade drill bodies.

This insert is intended for drilling steel and hard materials in industrial machining applications. The T-A Series spade drill system is widely used in CNC machining centers, lathes with live tooling, and manual drilling operations where a replaceable insert design reduces tooling cost compared to solid-body drills. The 63/64 inch diameter and Size 2 seat make this a common selection for hole-making operations in general metalworking and production manufacturing environments. Proper chip evacuation and coolant delivery are important considerations when using spade drills at this diameter in ferrous materials.

Key Features

• 63/64 inch diameter with a 132-degree point angle for efficient chip formation in steel
• Solid carbide construction at C5 (P40) material grade for rigidity and wear resistance
• TiAlN PVD coating extends tool life in ferrous and hard material applications
• T-A Series Size 2 seat for use with compatible Allied Machine T-A spade drill holders
• Replaceable insert design reduces per-hole tooling cost compared to brazed or solid-body drills
• 0.1875 inch insert thickness provides consistent seating and repeatable depth control

Compatibility

Designed for use with T-A Series Size 2 spade drill holders. Primary workpiece material compatibility includes steel (ISO P) and hard materials (ISO H) as specified in the product data.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before changing the insert, confirm the machine spindle is fully stopped and the tool is secured in a vise or tool block. Seat the insert firmly in the holder pocket and tighten the retention screw to the holder manufacturer's specified value using a calibrated torque tool. Inspect the seating pocket for chips or debris before each insert change to prevent misalignment and premature insert failure.
