## Description

Review: As good as branded router bits, this tool offers great durability and efficiency. - I used this router bit in a router sled I constructed to level my new hardwood tabletop, and it worked exceptionally well. However, be prepared for a significant amount of mess, so I'd advise using two dust extractors or vacuum cleaners. This router bit fitted and worked effectively with my Festool router. Even after levelling both sides for a solid hour of work, the tool remains sharp and ready to go again. It can remove over 5mm in one pass, though I would suggest making more passes with less material for better results. As good as Trend router bits, this tool offers great durability and efficiency for professional and DIY projects alike.
