Allied 1C23T-0118 Spade Drill Insert 1-9/16 in Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C23T-0118 is a solid carbide spade drill insert designed for high-performance hole-making in demanding machining applications. Part of the T-A Series, this insert measures 1-9/16 inches in diameter and seats in a Size 3 holder. It features a 132-degree point angle and a TiN (Titanium Nitride) PVD coating for extended tool life and reduced built-up edge. At 0.1 pounds, the insert is precision-ground to Manufacturer Grade C2 (K20), making it well-suited for aggressive interrupted cuts and high-feed drilling operations.

This insert is intended for use in CNC machining centers, drill presses, and manual turning applications where consistent bore diameter and surface finish are required. It is engineered for drilling stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium. Machinists and tooling specialists working in aerospace, automotive, and general manufacturing regularly specify T-A Series inserts for high-volume production runs where insert changeover speed and repeatability matter.

Key Features

• 1-9/16 inch diameter with Size 3 seat for direct holder compatibility
• Solid carbide construction at Grade C2 (K20) for hardness and wear resistance
• 132-degree point angle suits a wide range of workpiece entry conditions
• TiN PVD coating reduces friction and extends cutting edge life
• Rated for stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium
• Part of the T-A Series, a widely used indexable spade drill platform

Compatibility

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

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before seating or removing the insert. Use the appropriate torx or hex key as specified by the holder manufacturer to achieve proper clamping torque. Inspect the seat pocket for chips or debris before each insert change to prevent seating errors and premature insert failure.
