💡 Why is a combo sander and grinder handy for workshop benches?
To tame different materials safely, you gotta dial in friction heat and cut rates on the fly. Dropping or raising RPM stops scorch marks and keeps steel blades from overheating.
- High RPM bands strip heavy scale off flat iron stock
- Low RPM paths prevent scorch marks on soft pine
- Quick tension release saves time when swapping paper
- Thermal overload trips early during jammed cutting loads
