I'm gearing up to fit some 40mm oak worktops. I've got a panther blade for rip cuts.
My problem - I'll also be cutting out an undercount belfast sink. As I'm not great with a router, I was going to try using my plunge saw. The idea is to drill out two 16mm holes and then cut to them. The problem is the back cut as its the only one that will require a plunge.
My plan is to do it in as many passes as it takes, but I'm worried about that back cut. I've never plunged into something as dense as these worktops before and need to get it right (I'll test on offcut first). I'm worried about kickbacks/burns etc.
Any advice on this back cut? Will it make a difference if I remove the waste with a jig saw first so that the fibres are less tight? Is a panther blade the best tool for a plunge cut like this or would I be better off with more teeth? Will it make a difference if the back edge of the blade starts in the hole, or should I just get in there!?
