Allied Machine 1C23A-0114 Spade Drill Insert 1-7/16 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C23A-0114 is a solid carbide spade drill insert designed for high-performance hole-making in demanding materials. Part of the T-A Series, this insert measures 1-7/16 inches in diameter and seats in a Size 3 holder. It features a 132-degree point angle and a TiAlN (Titanium Aluminum Nitride) PVD coating applied over a C2 (K20) carbide grade substrate. Machining professionals and tooling specialists use this insert when drilling stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium where tool life and dimensional accuracy are critical.

This insert is suited for production drilling operations in CNC machining centers and manual boring mills. Its PVD TiAlN coating reduces heat buildup and extends cutting life in high-temperature alloys and abrasive materials including stainless steel and titanium. The T-A Series spade drill system is a common choice in aerospace, energy, and general metalworking environments where large-diameter holes are drilled at depth without the cost of solid round tooling. The insert is a consumable replacement component that mounts into a compatible T-A Series body and holder of matching Seat Size 3.

Key Features

• 1-7/16 inch cutting diameter for large-bore drilling applications
• Solid carbide construction, grade C2 (K20), for rigidity and wear resistance
• 132-degree point angle suited to a wide range of workpiece materials
• TiAlN PVD coating reduces thermal wear and extends tool life in difficult materials
• Compatible with stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium
• T-A Series design for use with standard Seat Size 3 drill bodies

Compatibility

Designed for use with T-A Series spade drill holders and bodies accepting Seat Size 3 inserts. Compatible primary workpiece materials include stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium (material codes M, K, N, S).

Installation Notes

Installation should be performed by a qualified machining technician. Ensure the drill body and holder are clean and free of chips or debris before seating the insert. Torque the insert clamp screw per the tool body manufacturer specifications. Verify proper coolant flow and spindle RPM and feed rate settings before engaging the workpiece, as improper parameters will reduce coating life and insert performance.
