Allied Machine 152A-1.015 Spade Drill Insert 1-1/64 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 152A-1.015 is a cobalt spade drill insert designed for high-performance deep-hole and through-hole drilling operations. Part of the T-A Series, this insert seats in a Size 2 holder and features a 132-degree point angle optimized for fast, accurate entry into ferrous and exotic workpiece materials. The TiAlN PVD coating delivers elevated heat resistance and extended tool life in demanding cutting environments. At 0.1875 inches thick and 1-1/64 inches in diameter, this insert is a purpose-built replacement for worn or damaged T-A Series spade drill tooling in production and job-shop settings.

This insert is engineered for drilling into steel, stainless steel, cast iron, super-alloys, and titanium, covering ISO material codes P, M, K, and S. It is suited for CNC machining centers, lathes with live tooling, and dedicated drilling machines where consistent hole geometry and tool life are critical. Typical applications include structural fabrication, aerospace component machining, mold and die work, and general metalworking production. The T-A Series spade drill system is widely used when deep drilling with coolant-through holders is required.

Key Features

• 1-1/64 inch cutting diameter with Seat Size 2 compatibility for T-A Series holders
• 132-degree point angle for fast penetration and self-centering entry
• Cobalt substrate provides superior hardness and thermal resistance over standard HSS
• TiAlN PVD coating reduces friction and extends tool life in steel, stainless, and titanium
• Rated for ISO material groups P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium)
• 0.1875 inch insert thickness for rigid seating in T-A Series blade holders

Compatibility

Designed for use with ALLIED MACHINE AND ENGINEERING T-A Series Seat Size 2 spade drill holders. Compatible with primary workpiece materials including steel, stainless steel, cast iron, super-alloys, and titanium as specified by the manufacturer.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the holder is fully de-energized and the spindle is locked before seating or removing the insert. Use the correct T-A Series insert screw and the manufacturer-specified torque driver to secure the insert flush against the blade seat. Inspect the seating pocket for chips or debris before installation to prevent insert rocking or premature failure.
