Replaceable Single Tip Drill for Small and Deep Hole Boring in Oil and Gas Applications

Allied Machine & Engineering Corporation (Dover, OH) offers their BT-A Drill that is compatible with standard BTA-STS (Boring Trepanning Association) systems. It works greatfor small and large deep hole boring applications in equipment for oil and gas drilling, as well as gun barrel drilling and mold and die making. With its balanced cutting forces, this drill offers up to twice the feed rate of competitive options, depending on machine capability. The BT-A Drill’s design features a laser clad bearing area for improved straightness and replaceable cutting edges to eliminate the need for resharpening. The insert geometry and polish significantly increases penetration rates compared to brazed heads and traditional gun drills. In addition to drilling long and deep holes, it is also an excellent choice for cross-hole drilling because its longer bearing surface length offers increased stability.

The BT-A design includes a geometry specifically developed to create the smallest chips possible, ensuring chips evacuate properly. 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 a great advantage to manufacturers seeking to keep sensitive monitoring equipment from stopping production. In tests conducted for one manufacturer, the BT-A Drill achieved significantly better chip control than a brazed carbide competitor, producing four tubes, 80 in long at 6 ipm.
