Hello all, i just got my first biscuit joiner from HD, a Dewalt DW682K. I tried it out with some test plunge cuts on pine , poplar and 3/4” ply. I noticed on the ply and on one of the pine boards the tool produced smoke inside the dust catcher. I adjusted my rate of feed slower, and then a bit faster, and in both instances, it produced smoke and left burn marks in the slot cut.

Do I simply have a dull cutter? Also, I noticed the biscuits fit very loosely in the cut, and will fall out if I turn the board upside down. Is this how they should fit, or should they be a bit snugger?

Thanks for your replies.

I haven’t used the dewalt but own a porter cable. I had the exact same issue until I replaced the stock blade with one from CMT. No more burning or smoke. Biscuits in my experience are usually a little loose until they get wet.

just off the top

make sure the cutter is not on backwards
that would be my first guess
looking down from the top
the teeth need to be facing right
(the sharp tip)

like a saw blade they will cut
but burn and leave bad cuts

if it is right
in and out
for a clean cut
don’t keep plunging over and over
it can widen the slot
so the biscuits are loose

if that doesn’t work
take it back and try again

Smoke, electronics and wood? What is the problem?

I have the Dewalt biscuit joiner, and the biscuits fit snug in one direction, and allow play in the other direction. I have had great results with mine.
My first guess was the same as Patrons that the blade was installed backwards at the factory.
Second guess is the blade is defective. I run the stock blade, and it never smoked.
If it only smokes in pine and low grade plywood, I wouldn’t worry too much about it. There is a lot of resin in pine, and glue in plywood. Try some different plywood and some hardwood to see what happens.

Stick with it. It is a great tool.
By the way, I have found the Dewalt brand biscuits fit best. Even the Porter Cable biscuits are too loose for my taste.

Biscuits will always burn if you have the oven over 400 or leave them in too long. If you still have this issue try M&T, dowels or pocket holes.

I also have the DeWalt, and have not had any issue with burning, however I’ve only used it in solid maple. For the bisuits, make sure that the setting on your tool matches the size biscuits you’re using. That being said, I’ve had some that would fall out if I turned the piece over, and some that don’t. I don’t think biscuits are an exact science, since they’re designed to swell once the glue is added. I also have had better luck with the DeWalt ones.

Thanks for the replies, most were helpful. I’ll check the blade to make sure it was installed correctly. FWIW, I did have the biscuit size set correctly on the joiner.

Just out of curiosity, what’re you using this for? Are you doing something like attaching shelves to a case, or something else, like aligning a panel glue-up? I’ve found that using biscuits to align a glue-up, I still got far better results using cauls.

There’s another thread on here to do with planet warming. This thread has to do with joiner warming. Coincidence?

Hi BinghamtonEd,

I plan to eventually use this to join face frames, maybe small table tops, and other light applications.

Just a follow up in case someone gets a new biscuit joiner and has these symptoms. I called DeWalt and asked them to send a new blade. They did and the tool works just fine with the new blade.

I hate it when a biscuit joiner starts to smoke? What with all that information out there, you’d think that they knew better…... ha

So what was wrong with the old one? Defective? Dull?
