All Replies on Saw blade for splines in miters

A rip blade designated as FTG should do the trick for you.

cool. I had been doing a few with my combo dewalt blade when it dawned on me that the poor results were not me but the blade. I’ll look into some rip blades.

I have a Freud full kerf rip blade t h at works well.

Same here. I actually rarely use it for ripping…

Got a biscuit joiner? Those have flat top blades.

Never thought of that. You could make a jig to hold it 90 degrees to the corner. Same sort of “cradle” for the table saw.

I use the Freud LU87R010 which is a thin kerf flat tooth ripping blade – 24 teeth. It’s about $40 now at Amazon.

I like to be able to whittle away at things with my tennoning jig, so perfer the thin kerf. You might use more than one pass for your splines to get the kerf thickness you want. They also come in full 1/8” kerf. I don’t recall the part number.

[edit…] The full kerf is LM72R010, about $61 at Amazon.

For thicker kerfs, look at the box-joint blade set SBOX8.

You don’t need the full height of a 10” blade. You might find a 7 1/4” flat tooth blade even cheaper.

I would use one or both of the outer blades of a dado set. They are flat bottom.

The last I knew the Freud Diablo ripper uses an ATB grind, not an FTG. As mentioned, the Freud Industrial series LU87 or LM72 are FTG. So are the CMT 201.024.10/202.024.10, Infinity 010-024/010/124, Amana Tools RB1020. Some of the Bosch Pro rip blades are FTG too.

the dado blade sounds like a great idea. especially since I don’t use rip blades as of yet and I need a dado set for my porch swings. thanks!

On some dado sets, the outer blades have a beveled top on one side only—which is why you will find left and right hand blades. They will leave a Batman “ear” on your kerf. Be sure to check first.

I have two Freud sets (made in Italy); both are flat bottom so I assumed that they all are. I bought the negative hook angle set for my radial arm saw and it does a better job on plywood and melamine covered particle board. The other set I had for my table saw works well too, but is not safe on the radial arm saw—which is why I have two sets.
