Allied Machine 1C20A-0019 Spade Drill Insert 19/32 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C20A-0019 is a solid carbide spade drill insert designed for precision hole-making in demanding machining applications. Part of the T-A Series, this insert measures 19/32 inches in diameter with a 0.125-inch thickness and features a 132-degree point angle for accurate entry and reduced thrust. The TiAlN PVD coating provides high heat resistance and extended tool life when cutting abrasive or hard materials. Manufactured to a C2 (K20) carbide grade, this insert delivers the hardness and wear resistance required for high-feed drilling operations in production environments. It is installed by machinists and tooling technicians in CNC or manual drill press setups.

The 1C20A-0019 is suited for drilling stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium. The T-A Series insert system is a widely used indexable spade drill platform designed for interchangeability with compatible T-A Series holders in standard seat size 0 configurations. This insert is appropriate for both job shop and high-volume production environments where consistent hole quality and tool repeatability are required across a range of workpiece materials.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine before inserting or removing the drill insert. Seat the insert fully and evenly in the holder pocket and secure the clamping screw to the holder manufacturer's specified torque using calibrated tooling. Inspect the seating surface and screw threads for wear or contamination before each insert change to ensure proper clamping and runout.
