Customer Reviews

“Very good quality tool for a DIY’er like me. Put a Freud 80 tooth finish blade on it and it’s perfect for all kinds of trim work and wood flooring. It’s good for rough construction cuts too if the stock will fit. Very stable, safe, well made. I bought mine in 2005 and use it several times a year for DIY work. It was my first Bosch tool. I was very impressed and stick with Bosch now for just about all other tools.”

“I am new to owning a miter saw but after reading the reviews here found this was going to be my choice. The saw came out of the box and performed. The alignment was perfect. I’ve used it to cut and install baseboards and door trim and have had no issue. Crown molding is next on my list.”

  Christopher Hayes, Amazon Customer Review

“I just finished using my new Bosh 12″ miter saw to build a roof over and screen my 16′ X 20′ deck. It did a wonderful job of cutting right through 4 X 4 treated lumber, as well as the 2 X 6 treated boards stacked 2 high. I would recommend this saw to anyone with no resolutions. It is a great buy and works just as well as my neighbor’s higher priced DeWalt saw.”
