FD TC (two way cut) vs. FD UR (Ultra Reverse)?????

[oneleggimp]

I have looked long and hard at the drawings of both blades and their specs and I can't see any substantive difference.  I know a lot of you folks like the UR blade.  Does anyone know what the real difference between the two blades is and why you should choose one over the other.

 

Inquiring minds want to know.l

Two way cut (Crown Tooth) have 2 teeth up and two down making it reversable. Ultra reverse have 2 down and 1 up making it a one way blade with a reverse tooth.

Pretty much what Fred said. I have in the past used the crown tooth blades. I moved to the ultra reverse because i liked the way the handled better.This is just my personal preference.

Like Waye has said the UR seem to handle better for me...and it is really neat that the top of the blade is marked !

Both illustrations show the same tooth arrangement: 2 down and 1 up and the individual blade description on both blade styles is the same showing reverse tooth every third tooth so I remain confused.

I have used both rev. and crown saw blades. both by Olson I use the crown  cut blades on thicker stock 3/4 and larger. With olson's blades I don't have to sand the ends and use alcohol I used Olson right out of the container. and they don't rust even over the winter..   other than that there isn't enough difference I get about 1 hour out of each

Jerry i'm going to swich to the ultra reverse blades now that you brought this to light,Thanks,Ho HJo Ho here go to the "Gross-ery store"

With the Ultra Reverse blades you should only cut with one specific end in the down position. Because, the tooth pattern only goes so far up the blade. Whereas with the Crown tooth type of blades, you can install either end in the up/down position and the blade still cuts the way it's supposed to. And, that is because the tooth pattern is repeated along the length of the blade. So, with the crown tooth blades, you could get twice as much cutting done with one blade supposedly. Of course, that all depends on if you break the blade before you flip it over.

I bought a pack of blades for $3.00.  I read where someone wrote that a scroll saw blade should last around an hour.  Is that true?  I'm trying to find the size of a hex wrench that I can use to adjust my set screws.  Anyone know the size that would be used on the DW 788?

I have used a number of brands and styles of blades and never got a hour of use out of any. I cut hardwood, softwood and plywood. Best I get is 20 - 30 minutes.
