Allied Machine and Engineering’s T-A Pro drilling system combines material-specific insert geometries, redesigned drill body and proprietary coolant-through system for high-penetration drilling. According to the company, this enables penetration rates which run at speeds nearly 30% faster than other high-performance drills.

The company says that the coolant outlets are designed to direct maximum flow to the cutting edge, providing quick heat extraction where it is most critical, even at significantly higher speeds. Material-specific insert geometries are designed for effective chip formation, while the drill body incorporates straight flutes redesigned for maximum coolant flow and high rigidity. These design elements combine to extend tool life, create consistent quality holes and provide good chip evacuation. 

The T-A Pro drilling system is available in diameters ranging from 0.4370" to 1.882" (11.1mm – 47.80mm) and is said to be well-suited for holes ranging in stub, 3×D, 5×D, 7×D, 10×D, 12×D and 15×D depths. The drill comes in both imperial and metric shanks, with flat and cylindrical variants. The initial carbide insert geometries will work with steel (P) with AM300 coating; cast iron (K) with TiAlN coating; and nonferrous (N) with TiCN coating.


  • Broaching On A Lathe

    Producing a keyway, spline or similar longitudinal feature on a turned part usually necessitates an additional, time-consuming, secondary operation on a broaching or slotting machine. That means moving the part to and from a secondary operation, an extra setup, additional labor and hourly machine costs and all of the other headaches that go with secondary operations.

  • Thread Whirling Basics

    The rapidly increasing demand for high-value threaded parts with exceptionally high length-to-diameter ratios has created a lot of interest in thread whirling technology among American shops and manufacturers.
