Allied Machine TAP1-19.05 Spade Drill Insert 3/4 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING TAP1-19.05 is a carbide spade drill insert designed for high-performance drilling in steel and other ferrous workpiece materials. It carries a 3/4 inch diameter, a 132-degree point angle, and a T-A Pro series designation. The insert features an AM300 PVD coating applied over the carbide substrate to improve wear resistance and extend tool life in production drilling applications. At 0.1563 inches thick, it fits Seat Size 1 spade drill holders and is a direct consumable for shops running the T-A Pro modular drilling system. Installation and changeout are performed by machinists and toolroom technicians without removing the drill body from the spindle.

This insert is suited for drilling steel components in metalworking and machining operations, including production environments such as job shops, aerospace fabrication, and general manufacturing. The T-A Pro series is designed for through-coolant drilling and interrupted-cut applications where a standard twist drill would struggle with consistency and tool life. The AM300 coating targets steel cutting specifically, classified under ISO material group P, making this insert appropriate for carbon steels, alloy steels, and similar P-group workpiece materials.

Key Features

• Carbide substrate delivers hardness and edge integrity in demanding steel drilling operations
• AM300 PVD coating reduces heat buildup and flank wear when cutting P-group steel materials
• 132-degree point angle provides aggressive chip formation and reduced thrust in through-hole drilling
• T-A Pro series compatibility allows fast insert indexing without removing the drill body from the machine
• Fractional inch sizing at 3/4 inch diameter suits common bore requirements in standard machining programs

Compatibility

Designed for use with T-A Pro series Seat Size 1 spade drill bodies. No additional compatible model numbers or replacement part numbers were specified in the product data.

Installation Notes

Insert replacement is performed by machinists following standard toolroom procedures. Power down the spindle and secure the machine before changing inserts. Use the appropriate T-A Pro torx or hex key to seat and torque the insert screw per the drill body manufacturer guidelines. Inspect the insert seat for debris or damage before seating a new insert to ensure proper contact and runout.
