Aussel 6.35mm 1/4 Inch Shank Rabbeting Router Bit, T-Slot Rabbet Router Bit Grooving Bit with 6 Adjustable Bearings for Multiple Depths Woodworking

So far so good... this seems like a good bit. Some others have exploded on me, it's not the way I use them - they're just crap. This one has held up so far after cutting quite a few 12mm by 12mm rabbets in beech. I have also used the other bearings... it'd be nice if we could get one out to 19mm, but that's probably too much for a trim router with a thinner shank. However, you could obviously do it in multiple-passes... change of bits is easily done with the supplied hex key... it comes with a separate holder shank so the others all stay together.

The nut is so tight on the bit that unfortunately I cannot change the bearing out with another. The allen/hex key provided is now spinning around uselessly as the inside of the nut is completely stripped. Waste of money.
