Allied Machine 152N-0110 Spade Drill Insert 1-5/16 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 152N-0110 is a cobalt spade drill insert designed for high-performance hole-making in demanding metalworking applications. Part of the T-A Series, this insert measures 1-5/16 inches in diameter with a 0.1875-inch thickness and features a 132-degree point angle optimized for controlled entry and chip formation. The PVD-applied TiCN coating increases surface hardness and reduces friction, extending tool life in abrasive materials. It fits Seat Size 2 T-A Series spade drill holders 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, super-alloys, and titanium workpieces. The T-A Series platform is a common choice for through-coolant drilling setups in CNC machining centers, lathes with live tooling, and manual drill presses where indexable inserts reduce downtime compared to solid-shank drills. Its cobalt substrate provides toughness and heat resistance needed when cutting harder ferrous and exotic alloy materials.

Key Features

• 1-5/16 inches cutting diameter with 0.1875-inch insert thickness for rigid, stable cutting geometry
• 132-degree point angle suited for flat-bottomed entry and reduced thrust in harder materials
• Cobalt substrate delivers improved toughness and heat resistance over standard HSS inserts
• PVD TiCN coating increases surface hardness and lowers friction to extend tool life
• Designed for Seat Size 2 T-A Series holders for quick, repeatable insert indexing
• Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, and titanium

Compatibility

Designed for use with Seat Size 2 T-A Series spade drill holders. Compatible workpiece material classifications include P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium) per ISO material coding.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before indexing or replacing the insert, ensure the machine spindle is fully stopped, locked out, and the holder is clear of the workpiece. Seat the insert flush against the holder pocket and torque the clamping screw to the holder manufacturer's specification using the correct T-A Series wrench. Inspect the seat and clamping surfaces for chips or debris before securing the insert, as contamination in the pocket can cause insert rocking and premature failure.
