Ive been thinking of ordering up a makita die grinder for rot removal, but realised my Bosch gkf 600 might do the same job, it spins to 33000 rpm, only downside i can think of is it not having the thin long neck, but being a parm router is it still quite slim once guide sleeve is removed.
Might have to order a burr and try it out.
