Erbauer Biscuit Jointing Kit Â¼" Shank 4 Piece Set
Cuts like a hot knife .....
Using this tool with my router to create biscuit slots in IPE decking for the hidden fixings. Have heard stories of how IPE basically laughs in the face of cutting tools. This cutter laughed in the face of IPE. Cuts the slot with no problems - all clean with no burning or blunting of the edge - Cheaper than buying a dedicated biscuit cutter :)

Overall good quality cutter. Nice snug fit on biscuits but not too tight. Very pleased for the price

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.
