Allied Machine 1C23A-0128 Spade Drill Insert 1-7/8 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C23A-0128 is a solid carbide spade drill insert designed for high-performance hole-making in demanding machining applications. Built to T-A series specifications, this insert features a 132-degree point angle and a TiAlN PVD coating, which extends tool life and reduces heat buildup during cutting. At 1-7/8 inches in diameter with a Seat Size 3 designation, it fits directly into compatible T-A series spade drill holders. The C2 (K20) carbide grade delivers the hardness and wear resistance needed for production drilling. This insert is installed and replaced by machinists and tooling technicians in CNC and manual drilling operations.

This insert is suited for drilling stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering a broad range of workpiece material codes M, K, N, and S. It is commonly used in production machine shops, job shops, and manufacturing facilities where consistent bore diameter and tool life are critical. The T-A series modular design allows for quick insert changes without removing the holder from the spindle, reducing machine downtime.

Key Features

• Solid carbide construction in C2 (K20) grade for high hardness and abrasion resistance
• 132-degree point angle optimized for through-hole and blind-hole drilling
• TiAlN PVD coating reduces friction and extends tool life in high-temperature cutting conditions
• Compatible with stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces
• Modular insert design enables fast field replacement without removing the holder

Compatibility

Designed for use with T-A series Seat Size 3 spade drill holders from ALLIED MACHINE AND ENGINEERING. Suitable for workpiece materials classified under ISO material codes M (stainless steel), K (cast iron), N (non-ferrous metals), and S (superalloys and titanium).

Installation Notes

Insert replacement is performed by a machinist or tooling technician. Always power down and lock out the spindle before handling or replacing drill inserts. Use the correct torque wrench and insert screws specified for the T-A series holder to secure the insert properly. Inspect the holder seat for wear or damage before installing a new insert to ensure accurate seating and bore diameter.
