Drill for Deep Hole Boring

Allied Machine & Engineering Corp offers the BT-A Drill, compatible with standard BTA-STS (Boring Trepanning Association) systems. The BT-A Drill is suitable for small and large deep hole boring applications, including gun barrel drilling; mold and die making; as well as equipment for oil and gas drilling. "With its balanced cutting forces, the BT-A Drill offers up to twice the feedrate of competitive options, depending on machine capability," said a company spokesperson.

The BT-A Drill's patent-pending design features a laser clad bearing area for improved straightness, and replaceable cutting edges to eliminate the need for resharpening. "The insert's geometry and polish increase penetration rates compared to brazed heads and traditional gun drills. In addition to drilling long and deep holes, Allied's BT-A Drill is also a good choice for cross-hole drilling because its longer bearing surface length offers increased stability," said the spokesperson.

"Allied's BT-A design includes a geometry developed to create the smallest chips possible, ensuring chips evacuate properly," said the spokesperson. The polished insert minimizes edge buildup, which in turn limits the amount of pressure generated during the drilling operation. "This feature increases tool life and is an advantage to manufacturers seeking to keep sensitive monitoring equipment from stopping production," said the spokesperson.

"In recent tests conducted for a machine gun manufacturer producing 80-inch military gun barrels for helicopters and tanks, the BT-A Drill achieved better chip control than a brazed carbide competitor. One insert produced four tubes, 80 inches long, at 6 inches per minute," said the spokesperson.
