Allied Machine 1C52T-1.046 Spade Drill Insert 1-3/64 in

Product Description

The ALLIED MACHINE AND ENGINEERING 1C52T-1.046 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. With a 1-3/64 inch diameter and a 132-degree point angle, this insert provides precise entry geometry suited for demanding metal-cutting applications. The TiN (titanium nitride) PVD coating extends tool life by reducing friction and resisting wear at the cutting edge. It fits Seat Size 2 holders in the T-A spade drill system and is installed by machinists and tool-room professionals working with manual or CNC drilling equipment.

This insert is intended for use in T-A series spade drill holder bodies requiring a Seat Size 2 insert. Typical applications include production drilling in steel and hard material workpieces in manufacturing, job shop, and industrial settings. The C5 (P40) carbide grade makes it well suited for interrupted cuts and general-purpose steel drilling at moderate to high feed rates. Package quantity is 1 insert per package; minimum order quantity is 2 packages.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing inserts. Seat the insert flush against the holder pocket and secure the clamping screw to the holder manufacturer's recommended seating practice without over-torquing. Inspect the seat and insert pocket for chips or debris before each installation to maintain accurate positioning and prevent premature insert failure.
