Allied Machine 152T-0107 Spade Drill Insert 1-7/32 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 152T-0107 is a spade drill insert designed for high-performance hole making in demanding metal cutting applications. This insert measures 1-7/32 inches in diameter, seats in a Size 2 holder, and features a 132-degree point angle optimized for penetrating tough workpiece materials. Constructed from T15 grade cobalt high-speed steel, the insert carries a PVD-applied titanium nitride (TiN) coating for improved surface hardness and wear resistance. At 0.1875 inches thick, it is built to T-A series dimensional standards. Machinists and tooling technicians in production shops install this insert as part of a spade drill assembly on CNC machining centers, lathes, or drill presses.

This insert is suited for drilling steel, stainless steel, cast iron, superalloys, and titanium. It fits applications ranging from job-shop one-offs to production runs where repeatable hole quality and insert interchangeability matter. The T-A series is a fractional inch system, and this insert is dimensioned accordingly. Work material codes P, M, K, and S cover the primary materials this insert is rated to cut, making it a versatile option across ferrous and high-temp alloy workpieces.

Installation Notes

Spade drill inserts are installed and replaced by machinists or tooling technicians. Before changing an insert, power down and lock out the machine spindle per shop lockout-tagout procedures. Seat the insert fully against the holder pocket and torque the clamping screw using the manufacturer-specified wrench for the holder; do not use substitute tools that may cam out and damage the seat. Inspect the holder seat and coolant passages for chips or damage before seating a new insert.
