Joining apollo magna worktops.

[Bill Derr]

I have some Apollo Magna worktops to fit soon, these are a 6mm acrylic surface bonded to a chipboard core and are 34mm thick (customer has already purchased them) they are joined with a full length 6mm loose tongue and two pack resin - they say to route a 6mm slot 14/15mm deep in to both sides/faces of the joint edge but I am struggling to find a suitable cutter for that - any suggestions for making this slot please?

I enquired about using worktop bolts and the resin but they said to do so would void the warranty.

Grooving cutters will do this accurately by referring all the cuts of the top surface.
