"I bought this set to tackle my first Oak Worktop installation with a Trend Professional Jig and New Ebauer 1/2" Router. I decided to pay extra for this Trade Set rather than one of the cheaper options.
First cut (Male) was perfect. Second cut (Female) the Router suddenly shuddered badly and bits of shattered router blade ended up embedded in my worktop! Fortunately no Jig or Router damage.
I expect to get more than one cut out of a Bit. Maybe I was unlucky but my old TCT set I have had for 10 years still works like new. Maybe Solid Oak is harder that I thought!"
