Allied Machine TAP2-31.75 Spade Drill Insert 1-1/4 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING TAP2-31.75 is a solid carbide spade drill insert designed for high-performance drilling in steel workpieces. Part of the T-A Pro series, this Seat Size 2 insert features an AM300 PVD coating that extends tool life and reduces heat buildup at the cutting edge. With a 132-degree point angle and a thickness of 0.1875 inches, the TAP2-31.75 is engineered for precise, repeatable hole-making in demanding production environments. It is installed by machinists and toolroom technicians in industries where tight tolerances and consistent bore quality are required.

The TAP2-31.75 is suited for drilling applications in steel and similarly classified P-group workpiece materials. Its 1-1/4 inch diameter and T-A Pro series designation make it a direct-fit replacement insert for compatible T-A Pro spade drill holders of Seat Size 2. Typical use cases include production machining, job-shop drilling operations, and maintenance of drilling assemblies where the insert is replaced independently of the holder body to reduce tooling cost per hole.

Key Features

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before inserting or removing the drill insert. Seat the insert fully and evenly into the holder pocket and secure with the appropriate holder fastener to the holder manufacturer's specification. Inspect the holder seat for wear or debris before installing a replacement insert, as a damaged seat will affect insert clamping and hole accuracy.
