Allied Machine 152T-0109 Spade Drill Insert 1-9/32 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 152T-0109 is a spade drill insert designed for high-performance drilling in a wide range of ferrous and exotic workpiece materials. Built from T15 cobalt high-speed steel and finished with a PVD-applied TiN coating, this insert delivers strong wear resistance and heat tolerance at the cutting edge. The 132-degree point angle suits general-purpose drilling into steel, stainless steel, cast iron, superalloys, and titanium. At 1-9/32 inches in diameter with a Seat Size 2 designation, it fits the standard T-A spade drill body system used throughout production machining environments. Machinists and toolroom technicians working with tight-tolerance bore applications will find this insert a reliable workhorse consumable.

This insert is intended for use in T-A series spade drill bodies across CNC machining centers, drill presses, and turning centers where high metal-removal rates are required. It performs in both wet and dry cutting conditions and is particularly suited to applications involving steel and stainless steel components, cast iron housings, and difficult-to-machine superalloys and titanium alloys. The fractional inch sizing system makes it a natural fit for shops running inch-standard tooling programs.

Key Features

• 1-9/32 inch diameter for Seat Size 2 T-A series spade drill bodies
• T15 cobalt high-speed steel substrate for elevated red-hardness and wear resistance
• PVD TiN coating reduces friction and extends cutting edge life
• 132-degree point angle optimized for general-purpose drilling into ferrous and exotic alloys
• Rated for primary workpiece materials: steel, stainless steel, cast iron, superalloys, and titanium (ISO codes P, M, K, S)
• 0.1875 inch insert thickness for consistent seating and repeatable runout

Compatibility

Designed for use with T-A series Seat Size 2 spade drill bodies in the Allied Machine and Engineering T-A system.

Installation Notes

Installation is performed by a machinist or toolroom technician. Always de-energize and lock out the machine spindle before changing inserts. Seat the insert fully against the pocket locating surfaces and torque the clamping screw to the drill body manufacturer specification using the correct T-handle or hex key. Inspect the insert seat for chips or debris before seating a new insert, as contamination will affect runout and insert life.
