Has anyone been using Trend Craft Pro router bits and are they any good. The cheap set of bits that I'd bought many years before I became a guitar builder have outlived their usefulness.

I haven’t @robin but as far as I know Trend makes (or has made) good stuff. I imagine they will work for at least as long as your old bits, let us know how they perform.

I bought one during the summer to replace an old worn bit that I’ve had for years. I used it for the body on my practice electric build. It was good enough for the job, Tungsten Carbide is harder wearing than High Speed Steel but doesn’t take as good an edge in my opinion. I’ve used both on lathe turning and always get a better finish with HSS. Old worn bits can be sharpened slightly by using a diamond stone on the flat edge, so if you have one it’s worth a try.

I used one of my new ones yesterday, a much cleaner cut than my old ones.

@robin thank you for the suggestions , i don't have any idea about it. I will try...
