How to cut, drill and weld stainless steel: why is it workshop work?
Stainless steel is harder to work than ordinary steel. Although cutting and drilling at home is possible, precise and clean results require knowledge and equipment.
Drilling
Stainless steel work-hardens as it is machined. It must be drilled at low speed, with steady pressure, plenty of oil or coolant and a sharp bit. If the speed is too high the bit dulls and the area around the hole hardens.
Cutting
Sparks, heat and surface marks can occur during cutting. If carbon steel dust gets onto the surface during grinding, rust stains can appear later. That is why separate discs and tools are used for stainless steel.
Welding
Heat discoloration (blue-yellow marks) forms in the weld zone. This area has to be cleaned and the surface protected again. Otherwise the area around the weld stays open to corrosion.
Conclusion
For jobs such as shelves, frames, tables, or repeated parts for a venue, both dimensional precision and a clean surface matter. This kind of work gives much better results in a workshop with the right equipment. Share your drawing or dimensions and we'll send a written quote.
