Allied 153T-0123 Spade Drill Insert 1-23/32 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 153T-0123 is a cobalt spade drill insert designed for high-performance hole-making operations in demanding metalworking applications. Manufactured from Super Cobalt with a PVD-applied TiN (Titanium Nitride) coating, this insert delivers strong wear resistance and extended tool life compared to standard high-speed steel alternatives. It features a 132-degree point angle optimized for controlled penetration and reduced thrust. At 1-23/32 inches in diameter and 0.25 inches thick, it is sized for Seat Size 3 spade drill bodies and is installed by machining professionals in production and job-shop environments.

This insert is suited for drilling operations in steel, stainless steel, cast iron, superalloys, and titanium - corresponding to ISO material codes P, M, K, and S. The T-A Series designation places it within ALLIED's widely used modular spade drilling platform, which supports a broad range of insert diameters and seat sizes for both through-hole and blind-hole applications in manual and CNC machine tool setups.

Key Features

• PVD TiN coating reduces friction and increases surface hardness for longer insert life
• 132-degree point angle provides aggressive cutting action with reduced axial thrust
• 1-23/32 inch diameter, 0.25 inch thickness - fits Seat Size 3 spade drill bodies
• Fractional inch measurement system for straightforward sizing in inch-standard tooling setups
• Rated for steel, stainless steel, cast iron, superalloys, and titanium workpiece materials

Compatibility

Designed for use with Seat Size 3 spade drill holders in the T-A Series modular spade drilling system. Compatible workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and the tool holder is secured in a vise or fixture before seating or removing the insert. Use the correct insert screw and torque driver as specified by the holder manufacturer - do not overtighten or substitute fasteners. Inspect the seat pocket for chips or debris before mounting to ensure proper insert seating and runout accuracy.
