Allied Machine 180T-0017 Spade Drill Insert 17/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 180T-0017 is a cobalt spade drill insert designed for high-performance drilling in demanding machining applications. Part of the T-A series, this insert measures 17/32 inches in diameter with a 132-degree point angle and a seat size of 0. It carries a TiN (titanium nitride) PVD coating, which increases surface hardness and reduces friction during cutting. At 0.125 inches thick and weighing 0.1 pounds, it is a compact, single-use insert that replaces the cutting edge without replacing the entire drill body. Machinists and toolroom technicians install this insert into compatible T-A series spade drill holders.

This insert is suited for drilling operations in ferrous and exotic workpiece materials across job shops, production machining centers, and maintenance environments. It is rated for use in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. Typical applications include hole-making in structural components, flanges, and heavy-walled parts where a replaceable insert system reduces tooling cost per hole compared to solid drill designs.

Key Features

• 17/32 inches cutting diameter with seat size 0 for T-A series holders
• 132-degree point angle optimized for entry into steel and hard materials
• Cobalt substrate provides heat resistance and toughness in interrupted cuts
• TiN PVD coating improves wear resistance and extends cutting life
• Replaceable insert design reduces overall tooling cost per hole
• Rated for five primary workpiece material categories including super-alloys and titanium

Compatibility

Designed for use with T-A series spade drill holders that accept a seat size 0 insert. Verify holder seat size and insert diameter before installation to confirm proper seating and clamping engagement.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before changing the insert, ensure the machine spindle is fully stopped and the machine is in a locked-out, tagged-out state per facility lockout/tagout procedures. Seat the insert fully and flush against the holder pocket before torquing the clamping screw. Do not force or drive the insert into the pocket with impact tools, as this can damage the seating surface and affect runout.
