The drill bit and drill rod of the solid carbide gun drill are made of carbide, which is a whole, and its stability and efficiency are better than that of the welded gun drill.
Due to the small radial runout during processing, its life is also higher than that of welded gun drills.
Another feature of this gun drill is that a cylindrical needle shaft is processed on the gun handle, and then the drill rod and the cylindrical needle shaft are welded.
