Allied Machine 152N-0106 Spade Drill Insert 1-3/16 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 152N-0106 is a cobalt spade drill insert engineered for high-performance hole-making in demanding industrial drilling applications. Part of the T-A Series, this insert features a 132-degree point angle and a PVD-applied TiCN coating that increases surface hardness and reduces friction at the cutting edge. At 0.1875 inches thick and designed for a Seat Size 2 holder, it delivers consistent, repeatable performance in production environments where insert-style tooling is preferred over solid drills. Licensed machinists and tooling specialists install this insert as a consumable component in T-A Series spade drill bodies.

This insert is suited for use in machining centers, lathes, and dedicated drilling equipment operating on a range of workpiece materials including steel, stainless steel, cast iron, super-alloys, and titanium. The 1-3/16 inch cutting diameter makes it appropriate for mid-range bore sizing in both job-shop and production-floor scenarios. It is a direct consumable for any Seat Size 2 T-A Series spade drill body where a cobalt, TiCN-coated insert of this diameter is specified.

Key Features

• 1-3/16 inch cutting diameter for mid-range bore applications
• Cobalt substrate provides toughness and heat resistance in interrupted cuts
• TiCN coating applied via PVD process for improved wear resistance and reduced built-up edge
• 132-degree point angle optimized for general-purpose drilling geometry
• Seat Size 2 interface ensures secure, repeatable seating in compatible T-A Series holders
• Rated for steel, stainless steel, cast iron, super-alloys, and titanium workpiece materials

Compatibility

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

Installation Notes

Installation is performed by a qualified machinist or tooling technician. The machine spindle must be fully stopped and the tool body secured in a vise or holder before inserting or replacing the spade drill insert. Use the appropriate T-A Series insert wrench or torx key as specified by the drill body manufacturer to achieve proper seating — do not overtighten by hand or with improvised tools. Inspect the seat pocket for chips or wear before installing a new insert to ensure accurate positioning and safe cutting performance.
