Good value
Good value bit for a DIY’er like myself with impressive results, really good finish.

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.

Don’t bother with this cheap rubbish
Awful. Used for not much more than 10 minutes and it started burning its way through my piece of work, blunt. I’ve returned it for a refund, not fit for purpose. Would give no stars if it let me. Will buy British made in future, even if they are a lot pricier

Good cutter for the price
Used on a dewalt router with a sled to flatten out some oak sleepers. Used on both sides of 5 sleepers so far. Very impressed with finish and still some life left in the cutter.
User
Very good product.
Size was good and work well easily cutting through different strengths of timber with no loss of sharpness

Check diameter of your router base hole
Works great but may not fit through your router base. I had to fit it sticking out below the base and remember to not release it fully when finished.
