Allied Machine 150T-.578 Spade Drill Insert 37/64 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 150T-.578 is a spade drill insert designed for high-performance hole-making in demanding metalworking applications. It features a 37/64 inch diameter, a 132-degree point angle, and is manufactured from T15 cobalt high-speed steel for excellent wear resistance and heat tolerance at elevated cutting speeds. A physical vapor deposition (PVD) TiN coating reduces friction and extends tool life. At 0.125 inches thick, this Seat Size 0 insert fits the T-A series spade drill body system and is installed by machinists and toolroom technicians in production and job-shop environments.

This insert is suited for drilling operations in steel, stainless steel, cast iron, superalloys, and titanium. The T-A series system separates the drill body from the cutting insert, allowing the insert to be replaced independently without scrapping the holder. Typical applications include through-hole and blind-hole drilling on CNC machining centers, lathes, and drill presses where consistent hole geometry and tool life are critical. The 132-degree point angle is well-matched to harder workpiece materials that require a more aggressive cutting geometry.

Key Features

• T15 cobalt high-speed steel construction for heat and wear resistance
• TiN PVD coating reduces cutting friction and extends service intervals
• 132-degree point angle suited for steel, stainless steel, cast iron, superalloys, and titanium
• 0.125 inch insert thickness fits Seat Size 0 T-A series spade drill bodies
• Fractional inch system, 37/64 inch diameter for standard hole sizing
• Replaceable insert design lowers tooling cost per hole versus solid drills

Compatibility

Designed for use with T-A series Seat Size 0 spade drill bodies. Compatible workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium per material codes P, M, K, and S.

Installation Notes

Spade drill inserts are installed and replaced by machinists or toolroom technicians. Before changing an insert, ensure the machine spindle is fully stopped and locked out per your facility lockout/tagout procedure. Use the appropriate insert-seating tool or torque wrench recommended for the T-A series body to secure the insert — refer to the drill body manufacturer's documentation for seating specifications. Inspect the insert seat for chips or debris before installation to ensure proper seating and runout.
