Gun drilling, as the name suggests, is a specialized tool used for drilling deep holes, particularly in the manufacturing of gun barrels. This tool is meticulously engineered to achieve exceptional straightness, roundness, and surface finish in the holes it drills.

The applications of gun drills extend beyond gun barrel production, finding their place in various industries such as aerospace, automotive, mold making, medical devices, and hydraulics. Their utility in these sectors underscores the precision and quality they deliver in the drilling of deep and accurate holes.
