Replaceable-tip drill performs deep-hole boring

Allied Machine & Eng. Corp. offers the BT-A drill, compatible with standard BTA-STS systems. The drill is suitable for small and large deep-hole boring applications.

Its patent-pending design features a laser-clad bearing area for improved straightness and replaceable cutting edges to help eliminate the need for sharpening. The insert’s geometry and polish increase penetration rates compared to brazed heads and traditional gun drills, the company states.

The drill also is suitable for cross-hole drilling because its longer bearing surface length offers increased stability.
