Jul 25, 2024 · Gun Drilling & BTA Drilling: These are the right tools for the absolute deepest of Deep Hole Drilling. "Deep Hole" is defined by drill diameters, and specifically the depth to diameter ratio. When used properly, gun drilling can produce straight holes that are much deeper than conventional style drills are capable of.

The Deep Hole Gun Drill and its Function. A typical gun drill consists of three parts: a carbide tip, a heat treated alloy shank, and a steel driver. All are typically silver brazed together, and are designed to allow coolant to pass through its entire length.

Compare material, finish, length class, and decimal size equivalents. Also known as gun drills, use these bits to drill long, straight holes. A hole in the bit allows coolant to be channeled through the tool for more efficient chip evacuation.
