Allied 153T-0119-FB Spade Drill Insert 1-19/32 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 153T-0119-FB is a spade drill insert designed for high-performance drilling in demanding industrial applications. This insert measures 1-19/32 inches in diameter and seats in Seat Size 3 holders from the T-A series. It is manufactured from Super Cobalt with a TiN (titanium nitride) PVD coating applied to extend tool life and reduce heat buildup at the cutting edge. The 180-degree point angle produces a flat-bottom entry geometry suited for cross-hole, angled-entry, and interrupted-cut conditions. Machinists and tool-room professionals install this insert as a consumable replacement in T-A series spade drill bodies.

This insert is rated for use across a broad range of primary workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium, corresponding to ISO material codes P, M, K, and S. It is well suited for production drilling in aerospace, energy, heavy equipment, and general manufacturing environments where cobalt-grade tooling is specified. The fractional inch sizing makes it compatible with standard inch-system T-A series drill bodies used in CNC machining centers, turret lathes, and radial arm drill presses.

Installation Notes

Insert replacement is performed by a machinist or toolroom technician. Power down and de-energize the machine spindle completely before removing or seating the insert. Use the appropriate T-A series insert screw and driver to secure the insert to the drill body at the specified clamping torque listed in the drill body manufacturer documentation. Inspect the seat pocket for chips or damage before installing a new insert to ensure proper seating and runout.
