Thread: T&G Cutter, Life Span

12’ is a long length to be trying to pass over a lightweight table. You’ll need at least two each of infeed and outfeed rollers/stands.

Personally I’d use a handheld router for that job. If you have a Triton router the fence attachment can be used as a baseplate extension to assist stabilising the machine.

As for how long the cutters will last, well “it depends”. High quality router bits used at the correct cutting speeds and feed rates will show little wear after that lot, unless your “hardwood” is something evil with a high silica content.

I have the roller stands, but yes I take your point I have a big Makita so that would do the job I reckon

As CT says, provided your timber isn't horrible to machine in general (and clean from any dirt and other gunk), carbide bits will last a long time. They do like/need to be worked fairly hard though, if you're making dust instead of chips you're feeding too slowly which will result in excess heat and will send it blunt early.
