Rated 2 out of 5Â by timnicebutdim SLACK fit
Cutter is about 0.5mm too wide, and if you add in ANY wobble during the cut that gives you a slot 1mm over wide. So when you clamp 2 planks together, the drift can be up to 2mm.
This is real, I clamped up some oak boards today and was very frustrated by how much they drifted. Its going to take me many many hours to plane the boards flat now.
Any argument about the 'slot is slack to allow for the biscuit swelling' is talking rubbish. By the time the biscuit has swelled up your boards are already clamped up out of line. The whole point of the biscuit cutter is to align boards accuretely, not +/- 2mm !!
Otherwise, its really good: if you are not that bothered about alignment then rush out and buy.

Boben is correct - biscuits are designed to be a slack fit in the slot when dry and then swell to form a tight fit as they absorb the glue. But to achieve swelling, its essential that a water-based glue such as PVA is used. Solvent based or non water-based glues will not cause swelling, and while they might still act as gap fillers and secure the biscuit when the glue hardens, the joint will not be as strong or rigid as with a swollen biscuit.

The review by 'ViggenBoy' is misleading in stating that the biscuits are not a tight fit (don't be embarrased fella - it's a common misconception) the biscuits will always be slightly loose on first inserting them, they are however, designed to swell on contact with the glue to provide a tight joint. Once the glue is dry, you should have a strong joint.
Just ensure that the diameter of the bit will pass through the sole plate of your router.

Rated 3 out of 5Â by Viggenboy Cuts a slot too wide
Biscuits should be a good snug fit to make the parts align accurately and - particularly in chipboard- this cuts a slot too wide to make the biscuits a tight fit...
