Cutting into corner

[SteveF]

I am considering cutting an L shape into a solid worktop 900 x 900
leaving 900 450 450 450 450 900
what would be your favorite method to get a clean cut
and leave a crisp internal corner?
yes I could just track saw it and reglue, if that is best approach

The kitchen fitters will be along with the correct solution shortly, no doubt, but if it were me I would probably cut 4 or 5mm from the line with a circular saw and a hand saw to remove the bulk of the waste, then use a trimming router cutter with a bearing guide against a template to clean everything up, and then finally tidy up the radius to the inner corner with hand-tools (a chisel if the worktop was timber).

I’ve done it it more or less how Mike suggests, though I used the track saw to cut to the line, finished it off with hand saw, then rounded over the top edge with the router.
