Allied Machine unveils drilling system

Allied Machine is releasing its high-penetration drilling system, the T-A Pro. The T-A Pro drill combines material-specific insert geometries, a redesigned drill body and a proprietary through-coolant system to allow penetration rates which the company says run at speeds of up to 30% faster than other high-performance drills on the market.

Coolant outlets direct maximum flow to the cutting edge, providing quick heat extraction where it is needed most, even at significantly higher speeds. In addition, material-specific insert geometries produce good chip formation, while the drill body incorporates redesigned straight flutes for maximum coolant flow and rigidity.

These design elements combine to extend tool life, create consistent-quality holes and provide chip evacuation. As a result, the T-A Pro drill is said to offer machine shops and high-production manufacturers a spade drill with high speed and cost per hole averaging 25% less than existing drills.

The T-A Pro drilling system from Allied Machine is available in diameters ranging from 11.1 to 47.0 mm, and is suitable for stub, 3xD, 5xD, 7xD, 10xD, 12xD and 15xD hole depths. Allied Machine’s drill comes in both metric and imperial shanks, with flat and cylindrical variants. The carbide insert geometries will initially cater for the following ISO material classes: steel (P) with AM300 coating; cast iron (K) with TiAlN coating; and non-ferrous (N) with TiCN coating.

Product manager Sal Deluca says: “The T-A Pro drill is designed for use in applications ranging well beyond general-purpose drilling. It truly will target all industries, offering phenomenal tool life at high penetration rates, especially in situations where the balance of chip formation at high penetration is critical.”
