What is it?
The Metal Mitre Saw is a mitre saw for metal.
It differs from many other saws in that it has a slow-turning saw-blade and a cooling mechanism, allowing to cut metal without getting it hot.

The Metal Mitre Saw is located in the Welding area.
Accessories:
- The wrench for replacing the blades is located behind the machine on the wall
- The saw blades are in the black closet next to the air compressor
- Cutting fluid and gearbox oil are in the blue closet in the metal area
