I have been using this tool for the deep trays I am making that are in the area of 3” thick and it cuts very nice.
I will give the tool a 5 star review, but I wish there was a section for me to review MJ lol. I would give him 10 stars as he has been beyond helpful with answering my questions and providing a few tips that really saved the day a time or two. I am new to owning a cnc router and between the high quality tools and the support, I will be back to buy more in the future. Thank You.
