Dewalt Biscuit Joiner Review

Dewalt Biscuit Joiner Review

Dewalt is one of the most iconic brands available today. I look at them somewhat like the Yankees in that those who are loyal to them, are die hard. I love Dewalt as well, and like Bosch and a few other names, I feel like if you can afford the jump in cost, they are always worth it. With cordless technology booming, what happens to the old corded classics? Well, today we look at a wood shop staple, a biscuit joiner. Does Dewalt still make some of the best tools? Well, let’s find out in the Dewalt Biscuit Joiner Review.

Dewalt Biscuit Joiner Review Overview

Biscuit joiners are also known as plate joiners and were invented in Switzerland by Hermann Steiner in the 1950’s. He eventually went on to form a company called Lamello that still makes biscuit joiners today. There aren’t a ton of manufacturers that still produce biscuit joiners, but it isn’t a tool you want to scrimp on. Biscuits are essentially compressed wood that is inserted, usually with glue into a small groove cut by the joiner. They are used in a lot of different ways, most commonly for joining long lumber together for things that need a flush joint like table tops. They also are used in things like joining 90-degree edges or as a substitution for mortise and tenon joints.

I have had my eye on a biscuit joiner for years and had a hard time justifying it since my woodworking is still on a hobby basis. For a professional woodworker or carpenter, it’s certainly a must though. I watched and researched a million different ways to get around actually buying the tool, but really there just isn’t. I have plans drawn out for a large dining room table and benches, so the time had come to actually take the plunge.

The height adjustment settings allow you to adjust the height of the biscuit placement based on what size wood you are working with. Additionally, this helps when joining the pieces together as it keeps them parallel for the best fit. Adjustments are made by simply turning the knob, and locking it into place.

Dewalt Biscuit Joiner Review Performance

Dewalt Biscuit Joiner Review

The Dewalt Biscuit Joiner is yet another winner for Dewalt. While I am not surprised that Dewalt made such a great tool, I am surprised at just how simple it is. Biscuits can’t possibly replace every form of joining. Having said that, after using this I can see why they have such a solid spot still in woodworking. Dewalt designed a powerful machine to ensure it could handle hardwoods and not bog down, which so far has proved to be the case.

Dewalt designed this tool well. It is solid but isn’t overly heavy. The dust collection system works incredibly well at collecting shavings, and the included adaptor works well. The fence allows for perfect alignment and the depth of cut is consistently accurate. The way the biscuit joiner works is by aligning the fence in place, depressing the trigger until the motor is up to full speed and then you plunge it in to actually expose the blades to the wood. All in all, its an incredibly easy to use tool that simplifies a lot of joining in the workshop.

Dewalt Biscuit Joiner Review Value

The Dewalt Biscuit Joiner, Model #DW682K retails for $169.00 at The Home Depot. Is it the cheapest Biscuit Joiner? No, but by no means does it fall at the top end of the market either. There are several professional brands that cost multiples of this version, so in this case, the price point is fair for the hobbyist like myself. If I were to come up with one small gripe, its that they should have included some biscuits to start with, and even that is insignificant in the grand scheme of things. The quality of materials and performance make it an excellent value. To me, on a dining table alone, this tool will be worth the price.

Dewalt Biscuit Joiner Review Final Thoughts 

What can I really say? I love this tool. This tool is well made, easy to use and efficient. Dewalt thought this tool through really well and its simplistic design allows for quick and simple cuts. Biscuit use can drastically improve the outcome of a lot of projects in the workshop. For anyone looking to take their woodworking to the next level, the Dewalt Biscuit Joiner may be a really great tool to add to their collection.


  1. I have debated getting a biscuit joiner for awhile now. I have been using dowels but putting them in manually. This looks like it would be so much easier, I cannot justify a Festool Domino so I think the biscuit joiner is a better option.

    • I completely understand. I really want the Domino at some point, but it’s hard to make that kind of investment. I was really impressed with this one! It is super simple and easy to use! I had no idea what to expect, but I really like it!

  2. Porter cable has been the cream of the joiner for years, how would you rate the Dewalt against it. I have been on the fence for a while about buying one. Especially now that I only do woodworking as a hobby.

    • That’s a great point! I would imagine that Dewalt will launch one eventually. Battery technology is definitely there, but I would be curious about the ergonomics with a battery on it. It’s a great little unit, definitely something I use quite a bit now!

  3. I use a makita cordless biscuit jointer and it works a treat and as you say the battery technology is available.
    Come on Dewalt make my tool kit a makita free zone ??.

  4. I use the VonHaus biscuit joiner for almost one year. I also love battery-powered biscuit joiner. It’s more comfortable for me. I have no idea about the Makita biscuit joiner brand.

    Either way
    Very helpful images to understand your share.
    Keep it up.
