Allied Machine and Engineering 152T-0112 Spade Drill Insert

Product Description

The ALLIED MACHINE AND ENGINEERING 152T-0112 is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. Part of the T-A series, this insert features a 132-degree point angle and a physical vapor deposition (PVD) TiN coating that extends tool life and reduces friction at the cutting edge. Manufactured from T15 material grade cobalt, the insert measures 1-3/8 inches in diameter with a 0.1875-inch thickness and fits a Seat Size 2 holder. It is installed by machinists and toolroom professionals in production and job-shop environments where consistent bore quality is required.

This insert is suited for drilling steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material groups P, M, K, and S. The T-A series spade drill system is a widely used modular drilling platform in CNC machining centers and manual lathes. The 152T-0112 is a fractional-inch insert intended for applications requiring a 1-3/8-inch hole diameter in medium to heavy material removal scenarios. It is commonly used in manufacturing, repair, and fabrication shops where a variety of workpiece materials must be processed with a single tooling platform.

Key Features

• 1-3/8 inch cutting diameter for consistent bore sizing in fractional-inch applications
• 132-degree point angle optimized for entry and chip formation across multiple material types
• Cobalt T15 material grade provides heat and wear resistance in hard or abrasive workpiece materials
• PVD TiN coating reduces built-up edge and extends insert service life
• Seat Size 2 compatibility fits standard T-A series spade drill holders
• Fractional-inch measurement system for direct compatibility with inch-based tooling setups

Compatibility

Designed for use with T-A series Seat Size 2 spade drill holders. Compatible with workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium (ISO material groups P, M, K, and S).

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before replacing the insert, confirm the machine spindle is fully stopped and the tool holder is secured in a locked or fixtured position. Seat and clamping surfaces should be clean and free of chips or debris before seating the insert. Consult the T-A series holder documentation for recommended clamping torque and coolant delivery setup.
