Our Verdict on the WORX WX845.9 Mitre Saw

Tool Only

Tool, Battery & Charger

Just above we have shown this available as a tool only, or if you prefer supplied with a battery and charger. Buying it with the battery and charger will initially be more expensive. However, you can then use the battery and charger for other compatible WORX power tools.

Some UK buyers prefer the WORX brand and they do make an affordable range of power tools that are very good quality.

This mitre saw does have a nice range of useful features.
