The disc drill set/step drill set contains disc drills for drilling holes of different sizes in soft metals. Suitable for sheet metal, soft metals such as copper, brass and aluminium, stainless steel and plastics.
The step drill is an excellent tool for drilling through holes for electrical wiring in cabinets and panels for installation. Also suitable for making pipe penetrations and inspection holes in plumbing work.
One drill bit can be used to drill holes of different sizes by pushing the drill bit to the desired depth. Each step increases the hole to be drilled by one notch.
