Replaceable drilling insert builds on 35 years of success at Allied

Sal Deluca, product manager at Allied Machine & Engineering introduces the replaceable insert drilling system, T-A Pro.

After 35 years of spade drilling success with its T-A (Throw Away) insert, Allied has developed technology that, according to the company, takes general purpose hole making to a performance level previously unachievable by a spade insert.

Allied says 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 run at speeds up to 30% faster than other high performance drills on the market.

Coolant outlets are designed to direct maximum flow to the cutting edge providing quick heat extraction where most critical – even at significantly higher speeds. Material-specific insert geometries produce highly efficient 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 is said to offer machine shops and high production manufacturers a high-speed spade drill and a cost per hole averaging 25% less than existing drills.
