Allied 15ZT-0014-FB Spade Drill Insert 7/16 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 15ZT-0014-FB is a cobalt spade drill insert designed for high-performance drilling in demanding metalworking applications. Measuring 7/16 inch in diameter with a 180-degree point angle, this insert features a physical vapor deposition (PVD) titanium nitride (TiN) coating that extends cutting life and reduces built-up edge on the tool face. With a thickness of 0.0938 inches and a Seat Size Z designation, it is engineered to seat precisely in compatible T-A series spade drill holders. Installation and use are carried out by machinists and toolroom professionals working on CNC and manual drilling equipment.

This insert is intended for drilling operations across a broad range of primary workpiece materials including steel, stainless steel, cast iron, super-alloys, and titanium. The T-A series platform is a widely used modular spade drill system, making this insert applicable in production machining, job shop environments, and maintenance repair operations where consistent hole quality and tool economy are priorities. Sold individually per package, with a minimum order quantity of 2 units.

Key Features

• Seat Size Z ensures precise, repeatable seating in the corresponding holder body
• Compatible with steel, stainless steel, cast iron, super-alloys, and titanium workpieces
• Thickness of 0.0938 inches for dimensional consistency across replacements

Compatibility

Designed for use with T-A series spade drill holders accepting a Seat Size Z insert at 7/16 inch diameter. Compatible workpiece material codes include P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium).

Installation Notes

Insert replacement should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per applicable safety procedures. Seat and clamping surfaces should be cleaned and inspected for wear or debris before seating the new insert. Torque the clamping screw to the holder manufacturer specification found in the tooling documentation — do not use substitute fasteners. Confirm insert seating and runout before resuming production cuts.
