It would be one heck of a deal if they were any good . I buy Freud bits individually,as I’ve had great success with them .
I bought a set of generic router bits at Canadian Tire way back in the day , and on mdf I got about six inches of round off till it began smoking.
Just saying that that was it for me and kits , but I have no experience with the ones your looking at
These guys make a good point regarding shaft size . I prefer the 1/2” shaft also , as I’ve had a 1/4” one bend
I donít always insulate , but when I do .
Ok ,I never insulate
