Stainless Steel Gun Drilling Die offered by us is very efficient and is a precision drilling process that produces deep, straight holes in a variety of specialty alloys. A gun drill tool differs from a conventional twist drill by its unique head geometry. Gun drilling is a deep hole drilling process that uses a long, thin cutting tool to produce holes in metal at high depth-to-diameter ratios. Gun drills are straight fluted drills which allow cutting fluid to be injected through the drill's hollow body to the cutting face. The Stainless Steel Gun Drilling Die is very easy to install wherever needed.
