Allied 15ZT-0016-FB Spade Drill Insert 1/2 in Cobalt Tin 180

Product Description

The ALLIED MACHINE AND ENGINEERING 15ZT-0016-FB is a cobalt spade drill insert designed for high-performance hole-making in demanding materials. Measuring 0.5 inches in diameter with a 180-degree point angle, this insert seats in a size Z holder within the T-A spade drill system. The TiN coating is applied via PVD process, increasing surface hardness and reducing friction at the cutting edge. At 0.0938 inches thick and 0.1 pounds, it is a precision-ground, single-blade cutting insert intended for professional machine shop environments. Machinists and tooling technicians install and index these inserts as part of a modular boring and drilling program.

This insert is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, and titanium. Its cobalt substrate and TiN PVD coating make it appropriate for abrasive and work-hardening materials where high-speed steel would wear prematurely. It is intended for use in CNC machining centers, lathes with live tooling, or dedicated drilling machines where the T-A spade drill body with a size Z seat is already in use. It is sold individually but must be ordered in multiples of two.

Key Features

• Cobalt substrate provides increased heat resistance and wear life compared to standard HSS inserts
• TiN coating applied by PVD process reduces friction and extends cutting edge life
• 180-degree point angle suited for flat-bottom entry and through-hole drilling
• Fits size Z seat in the T-A modular spade drill body system
• Rated for steel, stainless steel, cast iron, super-alloys, and titanium workpiece materials
• Lightweight at 0.1 pounds for easy indexing and handling at the machine

Compatibility

Designed for use with T-A series spade drill bodies accepting a size Z insert seat. Compatible workpiece material codes include P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium).

Installation Notes

Installation is performed by a machinist or tooling technician. The machine spindle must be stopped and the tool holder fully secured before indexing or replacing the insert. Use the correct insert screw torque driver specified for the T-A body to avoid seat damage or insert movement during cutting. Inspect the seat for chips or debris before seating the new insert.
