Allied Machine 150T-15.5-FB Spade Drill Insert 15.5mm Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 150T-15.5-FB is a spade drill insert engineered for high-performance hole-making in demanding machining applications. Built from T15 cobalt high-speed steel and finished with a TiN (titanium nitride) PVD coating, this insert delivers heat and wear resistance in interrupted cuts and continuous drilling operations. It measures 15.5 mm (approximately 39/64 inch) in diameter with a 180-degree point angle and a thickness of 0.125 inches. The insert fits Seat Size 0 holders in the T-A spade drill series. It is installed by machinists and toolroom professionals working on CNC machining centers, manual drill presses, and turning centers.

This insert is suited for drilling into steel, stainless steel, cast iron, super-alloys, and titanium. Those material classifications correspond to ISO work material codes P, M, K, and S. The 180-degree flat point geometry is appropriate for flat-bottom entry conditions and is commonly selected for through-hole and blind-hole operations where consistent chip formation and hole quality are required. It is a direct replacement insert for T-A series Seat Size 0 spade drill bodies.

• 15.5 mm (39/64 inch) cutting diameter in a Seat Size 0 profile
• 0.125-inch insert thickness for rigid seating in T-A series holders
• Compatible with ISO material groups P, M, K, and S workpiece materials

Compatibility

Designed for use with T-A series spade drill bodies accepting Seat Size 0 inserts. Suitable for machining steel, stainless steel, cast iron, super-alloys, and titanium workpiece materials.

Installation Notes

This insert is installed and replaced by machinists or toolroom technicians. Power down and lock out the machine spindle before removing or seating the insert. Use the appropriate torx or hex key as specified by the drill body manufacturer to secure the insert clamp screw to proper seating without over-torquing. Inspect the insert seat in the holder for chips or debris before installing a new insert to ensure flat, secure contact.
