FORET ÉTAGÉ is a step drill bit used to drill or enlarge holes in thin sheet metal and plastics. It covers multiple diameters in one tool, making it ideal for creating clean, accurate openings up to 30 mm.
It covers diameters from 4 mm to 30 mm, with steps every 2 mm. This means you can drill several hole sizes using a single bit, reducing tool changes and improving efficiency on site or in the workshop.
The step drill is designed for materials up to 3 mm thick. It works best on thin sheet metal and plastics, where it can cut smoothly without overloading the bit or the drilling machine.
Yes, it is suitable for drilling studs, including back-to-back profiles, for routing cables or conduits. The stepped design allows clean entry and enlargement of holes without deforming the metal frame excessively.
Yes, it works well on many plastic panels when used at moderate speed. To avoid melting or chipping, apply light pressure and allow the bit to cut gradually through each step, especially on thinner plastic sheets.
A step drill combines many diameters in one tool, saving time and reducing bit changes. It also creates round, burr-reduced holes and is particularly convenient when you need to enlarge existing openings accurately.
No, it is not recommended for thick or hardened steel. It is optimised for thin sheet metal up to 3 mm. Using it on heavy plate can damage the cutting edges and reduce tool life quickly.
Use a standard electric drill or pillar drill with variable speed. For metal, a slower speed with cutting oil is ideal. For plastic, moderate speed and light pressure help maintain clean, smooth holes.
Clamp the workpiece firmly, mark the hole position clearly and start drilling with steady, controlled pressure. Let the bit do the cutting and stop once you reach the desired step. Do not force the drill beyond its capacity.
After use, clean off metal or plastic shavings and store the bit in a dry place. Avoid dropping it or letting the cutting edges knock against other tools. With proper care, the bit will stay sharp and accurate for many jobs.
