Allied 152H-0107-TC Spade Drill Insert 1-7/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 152H-0107-TC is a spade drill insert designed for high-penetration drilling applications in metal fabrication and machining environments. This insert measures 1-7/32 inches in diameter and features a 132-degree point angle for efficient chip formation and reduced thrust. Built from cobalt with an AM200 PVD coating, it delivers extended tool life in demanding cutting conditions. The 0.1875-inch thickness and Seat Size 2 designation ensure proper seating in compatible T-A series spade drill holders. Installation and operation are performed by machinists and toolroom technicians.

This insert is part of the T-A series and is engineered for use in ferrous and specialty metal drilling operations. It is rated for primary workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium. Typical applications include through-hole and blind-hole drilling on CNC machining centers, drill presses, and multi-spindle equipment in production and job-shop environments. The cobalt substrate and PVD coating make it well suited for interrupted cuts and work-hardened materials.

Compatibility

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

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine before changing inserts. Ensure the holder seat and clamping surfaces are clean and free of chips before seating the insert. Follow the holder manufacturer's clamping torque guidance and verify insert seating before resuming cuts.
