The extra gluing area produced by using this cutter makes for an incredibly strong edge to edge joint. With a maximum cutting depth of up to 38mm, most board thicknesses can be accommodated. Recommended for router table use only.

awkward .. dittoI agree with David B - this cutter is very awkward. I'm trying to joint lengths of 30mm thick timber and the setup is a real pain. Axminster .. do you have a setup guide for this bit to achieve the best results? I'm finding it impossible to get a clean finger and shoulder to achieve a perfect fit so any help much appreciated.

awkwarkI got this cutter to join boards for the purpose of making a work surface. Although I can't fault the quality of the bit, the design isn't quite right in my opinion. The cut depth of 38mm is impossible, I'll try an explain why. To cut at maximum depth you would be removing no material from either the top or bottom surface of the wood, thus leaving a 'finger' top and bottom. Now do this to the next piece and you have a joint where you are bringing finger to finger, not finger to groove. This is remedied only by utilising less than than the maximum depth of cut, which obviously loses the 38mm max. Secondly, unless you want to thickness your entire finished piece again, your top and bottom finger cuts are going to have to be no more than half sized to avoid getting into the next 'v' portion of the cutting bit. That only leaves you with about .5mm of material and bit of sanding can be enough to pull that right out if you don't go extra careful! Maybe I'm just heavy handed and lacking in experience with this thing, but it seems flawed to me.
