Allied Machine 150A-0017 Spade Drill Insert 17/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 150A-0017 is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. Part of the T-A series, this insert measures 17/32 inch in diameter with a 132-degree point angle and a seat size 0 profile. The cutting surfaces carry a TiAlN (titanium aluminum nitride) PVD coating, which improves heat resistance and extends tool life at elevated cutting speeds. At 0.125 inches thick and weighing approximately 0.1 pounds, this insert is a direct-fit replacement body for compatible T-A series spade drill holders. Machinists and tooling specialists install this insert in CNC machining centers and manual drill press setups.

This insert is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, and titanium workpieces, covering ISO material classifications P, M, K, and S. It is appropriate for both production-volume machining environments and job-shop applications where a single insert handles multiple material types. The T-A series is a well-established platform in through-coolant and non-coolant spade drilling, making this insert a standard consumable in aerospace, automotive, and general metalworking shops.

Key Features

• 17/32 inch cutting diameter with seat size 0 for T-A series holder compatibility
• 132-degree point angle optimized for chip formation in ferrous and exotic alloys
• TiAlN PVD coating improves heat resistance and tool life at high cutting speeds
• Cobalt substrate provides toughness and wear resistance in interrupted cuts
• Rated for steel, stainless steel, cast iron, super-alloys, and titanium (ISO P, M, K, S)
• Single-insert package quantity supports per-need tooling replenishment

Compatibility

Designed for use with T-A series spade drill holders accepting a seat size 0 insert. Suitable for workpiece materials classified under ISO codes P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium).

Installation Notes

This insert is installed and replaced by a machinist or tooling technician. Always power down and lock out the machine spindle before seating or removing the insert. Use the correct torx or hex key specified for the T-A series holder to achieve proper clamping without over-torquing the insert screw. Inspect the holder seat for chips or debris before installing a new insert to ensure proper seating and runout.
