No, this tool is best used with angle grinding discs only.

We suggest only using 4.5 in. angle grinding wheels so that they fit within the safety guard boundaries.

No, the arbor size (the diameter of the opening used to connect the wheel to the tool) will not match and will be smaller than what is required to safely use the tool.

The tool comes with a metal grinding wheel. There are accessory wheel options that can be used to remove rust and other surface coverings from metal.

We do not suggest cutting wood with this tool.
