Allied Machine 152A-0103 Spade Drill Insert 1-3/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 152A-0103 is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. This insert features a 132-degree point angle and a titanium aluminum nitride (TiAlN) PVD coating that extends cutting life and resists heat buildup at the cutting edge. At 1-3/32 inches in diameter and 0.1875 inches thick, it fits Seat Size 2 T-A series spade drill holders. It is installed and changed out by machinists and tooling technicians working on production or job-shop drilling operations.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, and titanium — covering ISO material groups P, M, K, and S. The T-A series spade drill system is commonly used in CNC machining centers, lathes, and drill presses where indexable tooling reduces downtime compared to regrinding solid drills. Typical applications include structural, aerospace, and heavy-equipment component manufacturing where consistent hole geometry and long tool life are priorities.

Key Features

• 1-3/32 inch diameter with 132-degree point angle for controlled entry and reduced thrust
• Cobalt substrate provides toughness and heat resistance in hard or abrasive workpiece materials
• TiAlN PVD coating improves wear resistance and allows higher cutting speeds
• Seat Size 2 T-A series fit for use with compatible Allied Machine spade drill holders
• 0.1875 inch insert thickness for rigid seating and accurate depth control
• Rated for steel, stainless steel, cast iron, super-alloys, and titanium workpieces

Compatibility

Designed for use with Seat Size 2 T-A series spade drill holders. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, and titanium (ISO material codes P, M, K, and S).

Installation Notes

Insert replacement is performed by tooling technicians or machinists with the machine fully stopped and spindle locked. Use the appropriate torx or hex key as specified by the holder manufacturer to seat and secure the insert without over-torquing the clamping screw. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert. Follow the machine shop's established speeds and feeds for the workpiece material and insert grade.
