About this Joint Cutter Set
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. This patent-pending innovation is easy to use: simply install the two 8-inch diameter, 5/8-inch arbor blades on a table saw with the blades back-to-back for 1/4-inch box joints, or face-to-face for 3/8-inch box joints. Combine this with Freud's Tico Hi-Density Carbide and Silver I.C.E. Coating, and you can make perfectly square and precise box joints quickly and cleanly the very first time. This set includes instructions for making box joints and building a box joint jig.

Key Tech Specs:

• Creates 1/4-inch or 3/8-inch box joints
• Silver I.C.E. coated blades
• 5/8-inch arbors

Applications
Use these blades on all table saws for cutting grooves to create box joints in hardwoods and softwoods.

Warranty
This set is covered by Freud's limited lifetime warranty.

Content: I bought this blade set to give me a perfectly square (flat) miter for a spline key.

I'm building interior shutters for my windows - lower half of the window, hammered glass shutters (to let light in while providing privacy). My frame for the shutter is 2.25" oak with a channel for the glass and using 45 degree miter cuts on the corners. A very weak joint for this.

I needed to strengthen the joints with the spline key, but finding a blade that cut square was impossible. All of the teeth cut angles, and this leaves a "V" shaped base on the cut. Also, I needed 1/4" for the cut, not 1/8 which a normal blade would provide.

I have the Excalibur dado blade from Craftsman (do they make these anymore?) but that also doesn't cut a perfectly square channel. I really didn't want to invest $100+ in another dado blade (one with two outside blades using extra blades between them to provide the width).

I researched my needs and encountered this blade. I thought it answered my needs, so I ordered it.

Note: I built a jig to hold the shutter so the corner can be cut.

The blade, using the 1/4" cut, cut the corner without any chipping or pulling when it exited the joint (oak can easily splinter if one is not careful). I was able to quickly and easily cut all 8 corners on my set of shutters and insert my splines without issue. I did wait until my cuts were made before I planed down the spline board so I was able to ensure the proper fit.

So, if you are making shutters or anything else with a 45 degree corner that needs additional support besides glue, this blade (and appropriate jig) make terrific cuts for spline keys.

Note: In shear laziness, I didn't want to change blades to rip the spline key oak after planing it to the proper thickness, so I set up my rip fence with this blade - it doesn't do a good job ripping - way too much to cut at one time. It did the job, but I won't do that again!
Summary: Perfect cuts!

Content: I used it right out of the box with the instructions for a jig and it performed as they say. I made 3 drawers for a computer desk and it only took a few tries to get the jig working very well.
Summary: Good choice

Content: These blades make perfect 1/4" and 3/8" box joints. I've also use them for dadoe cuts. A great set.

Content: I didn't really NEED this... Afer all, I already had a nice Freud Dado set and a #10 grind Forrest blade, both of which can do box joint cuts. But it sure is convenient to just throw the blades on and start cutting -- perfect 1/4 or 3/8 cuts, with no shims, adjustments, or multiple passes required.

Cuts very cleanly and makes a perfectly square bottom as needed for box joints. I have several other Freud blades, and like those the quality of this set is top notch.

Content: After trying to make a box joint jig and still not happy with the results, I was a bit hesitant about trying this set. Boy was I wrong! Following the easy to understand and easier to make instructions and jig, my first porject was a huge success. For me at least the price was a considerable amount, but will have a high quality addition to my tools for years to come....
