Carbide Insert For Gun Drill

If your gun drill is in need of an upgrade, you can now get one with a new carbide insert. These new inserts are easy to install and come in a range of different diameters and designs. These new tools are great for deep hole drilling, and offer an increase in penetration rate compared to brazed gun drills. They also feature an improved PVD coating and a dedicated carbide substrate.

A typical gun drill consists of a carbide tip, a heat-treated alloy shank, and a steel driver. Each of these parts is designed to withstand the extreme torques required by gun drilling, and are often silver brazed together. The shank needs to be properly formed and heat-treated, and it should be aligned with the carbide tip to absorb the whipping associated with high-speed drilling.

The benefits of carbide gun drills include high feed rates and increased tool life. In addition, they don't require sharpening, making them an economical choice for many applications. Nonetheless, they can produce less accurate drilled holes than solid carbide gun drills, which are more costly and difficult to use in smaller diameters.

While BTA Drilling is a faster, more accurate method, it is also bulkier and only works on larger diameter holes. Since BTA drills require large tools, many shops outsource the process to get the job done more efficiently. In contrast, a gun drill mounted on a lathe can handle deep hole drilling competitively.
