Rated 5 out of 5Â by Techieman Erbauer biscuit jointing kit
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...
