Freud Box Joint Cutter Set

Item #
90% of 100

Freud has developed a method of creating perfectly square, flat-bottom box joints, on a table saw without using a dado set or saw blade. The SBOX8 Box Joint Cutter Set makes box joint construction easy, producing strong, accurate joints without shims or awkward adjustments.

  • Patent pending innovation enables users to produce perfectly square, precise box joints quickly and cleanly the very first time-and every time
  • Includes instructions for making box joints and building a box joint jig
  • Unique tooth design delivers clean cuts through end grain.
  • Cuts perfectly square pins and flat-bottomed slots

TIP: Make test cuts and sample joints with your new SBOX8 before using it on your first project. Whenever possible, plan projects to use stock with a width that is an even multiple of either 1/4" or 3/8", resulting in joints with all pins and tails at full width.

Freud Box Joint Cutter Set
Absolutely the best and easiest way to cut clean, accurate box joints. Freud spent some time working this design out to cut either size joints with no setup, shims, or measurements to make. Simply stack the blades to cut either of the sizes and make the cut. The instructions are clear and include a design for a simple fixture to cut box joints easily. You'll wonder hoe you got along without this blade set!

Woodworking Experience:
Box joint cutter
I bought it to make finger joints but I got an order to make political sign frames, and the signs were just over 1/8" thick. I made a 1/4" groove in the center of the frame, 5/8" deep to accept the signs,. I could have used a standard blade and made two passes, but this saved me a lot of time. They worked great. The job more than paid for the set.

Woodworking Experience:
High quality versatile set that cuts clean
Nice blade set...nicest part is that both combinations fit in my existing throat plate. Built some box joint drawers and also used to make some shaker style cabinet doors--- easy to use as a general dado set in a pinch.

Woodworking Experience:
Great blades
These blades set up easily and cut a very crisp and accurate groove. Very satisfied and would buy again, but I believe that these blades will last a very long time, and buying again won't be needed.

Problem Solved
I purchased this cutter to solve a problem with set-up with a shop made box joint jig. I was having trouble with fit and 'blow-out' on the cut using my dado set. The Freud was very sharp and precise out of the box. I'm able to make very nice tight fitting joints with minimum trial and error. i'm very pleased with the purchase.

Good reviews, Have been using Freud dado set with shims and found a difference of .004 +/- depending on how much torque I put on arbor nut. Hope this solves problem.

Perfect for making joints with Incra box joint jig
Tim C on Nov 16, 2016
Comments indicate good quality box joints with this set. I am only concerned with 1/4" and 3/8" box joints. I think this set should work fine on my table saw.

For smooth flat-bottom grooves.
George C on Aug 4, 2015
Appears to be a good set and was less expensive than what was available where I bought my finger joint jig. I use Freud blades in my circular saw and find them to be of good quality.
Richard A G on May 16, 2015
The Freud name means quality. I already had a Freud dado set so I knew that this would be of the same high quality. I haven't used it yet, but I am sure that it will perform as advertised.

What is the minimum table saw requirement, in other words can either the Dewalt or Bosch bench top type saws work? THX
tkuff on Oct 3, 2016
BEST ANSWER: You might want to check with DeWalt or Bosch for there recommendation
I cannot use a dado stack on my dewalt 745, can I use this instead?
Scott F on Mar 21, 2017
BEST ANSWER: I used to have the 745 Dewalt and it has a smaller arbor, the box joint kit will fit on it but it is after all just for box joints, it will require multiple passes if used for Dados.
What is the size of the centre hole on the cutter blade please ?
Peter S on May 9, 2016
BEST ANSWER: This blade set has a 5/8" arbor
Will this box joint cutter set cut 1/2" box joints ?
Harvey H on Feb 28, 2017
BEST ANSWER: It would really depend on the jig you are/or are not using to cut the joints. If your jig is elaborate enough to move the material or allow the material to be moved 'sideways' then it could be used for this purpose. It was really designed for 1/4 and 3/8. But it is also simply a flat top dado stack as well, so you can use it any way you would enjoy using a double or triple wide saw blade.
I have an 8" stacked dado set. What are the advantages of using a box-joint set instead of the dado set?
Kevin S on Mar 9, 2016
BEST ANSWER: The Box Joint set gives a perfectly square cut. A Dato set gives more corner scoring that can show in a box joint.
Will this work on a Rigid 45171 table saw. The manual for said saw says to only use 6” dado. Since this product is 8” diameter I’m guessing not, but since it’s not a true dado set maybe it would work?
Kevin K on Sep 14, 2019
BEST ANSWER: I used it on the full sized Rigid table saw and it worked well. It is super sharp and made precise and clean cuts
Is there a 1/8" Box joint blade?
Pete on Mar 27, 2017
BEST ANSWER: Pete, yes there is. The set contains two blades. Each is 1/8". Use 1 blade for 1/8" box joints, both blades together for 1/4" joints. If you reverse the blades, backto back, you get a 3/8" joint. Set works very well. I use it often. Ed T.
I am wondering if I could use this box joint blade to cut a dado in the rails and stiles for a cabinet door ? -- I like the simple mortise/tenon cabinet door. The tenon is often visible on the top side, so its important to have a very square dado groove. Also, since I use 3/4 inch thick hardwood, the perfectly set up 1/4inch option on this blade set would really speed things up. I guess I am wondering if it would ruin the blade if you use it to cut a long dado, as opposed to just the short box joint end (which it is intended for). Hope my question is clear! Thanks
Karen w on Nov 16, 2016
BEST ANSWER: Dato blades are made from the same materials as any other blade from the same company. There should be no problem doing what you are thinking.
Will this work on a Sawstop with standard cartridge or do I need a dado cartridge?
Shawn R on Oct 1, 2016
BEST ANSWER: An 8" cartridge is required. So you must have the dsto cartridge.
Are these designed to stack (allowing a 5/8" joint) or are they intended to be used individually? Thanks, Pepper Hicks
Dave B on May 29, 2016
BEST ANSWER: They are meant to be staked. You set the blade one way you get 1/4" cut, you reverse one of the blades you get 3/8" cut. nice set of blades.
Is it possible to put 2 sets together and make 3/4" cuts?
Rodney W on May 11, 2016
BEST ANSWER: That would be an expensive option. If you are going to do a lot of 3/4 cuts I would suggest you buy a dado blade. If your use would be minimal you could make one cut and put a spacer on the fence and make a second cut to get the 3/4" cut you want.
How is this box joint cutter used differently from a data set?
popeye on Jan 8, 2016
BEST ANSWER: It's designed for two widths of box joint. 1/4 or 3/8 inch. Where a dato set will do many more widths. It does do an excellent job with box joints cuts.
