High-penetration drilling system

Allied Machine and Engineering’s T-A Pro high-penetration drilling system builds on 35 years of spade drilling success with the T-A (throw away) insert.

The T-A Pro drill combines material-specific insert geometries, a redesigned drill body, and a proprietary coolant-through system to allow penetration rates which run at speeds nearly 30% faster than other high-performance drills on the market.

Coolant outlets are 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 produce impeccable chip formation and the drill body incorporates straight flutes redesigned for maximum coolant flow and excellent rigidity.

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

The T-A Pro drilling system will be available in diameters ranging from 0.4370” to 1.882” (11.1mm to 47.80mm) and is ideal for holes ranging in stub, 3xD, 5xD, 7xD, 10xD, 12xD, and 15xD depths. The drill will be stocked in imperial and metric shanks, with flat and cylindrical variants.

The carbide insert geometries offered initially will cater to the following ISO material classes:

Steel (P) with AM300 coating

Cast iron (K), with TiAlN coating

Non-ferrous (N) with TiCN coating

The T-A Pro drilling system will be available to order from Allied Machine’s distributor partners in October.
