Topic tags/keywords: frued compound miter saw cms blade d12100x lu80 lu79

First post! Woot.

But seriously, i’ve been lurking for weeks now and I bought a dewalt dws780 that i used to install a 14’ load bearing wall in my recent home renovation as well as install 225sf of 3/4 oak flooring.

The stock blade was decent for these tasks, but i’m about to install moulding and need a new blade. I’ve read reviews and knotscott’s blog about how to pick blades, but I was wondering if anybody has used a frued diablo D12100X yet. I couldn’t find any reviews on here or recommendations

They have them at the local home depot, and normally I would wait and buy the best (within reason) online, but I was hoping to get cracking on this trim work ASAP. Is this a good blade for low/no tearout with trim work, or should I really wait and get order a frued blade like the LU80/lu79 series?

A coworker of mine said to stay away from the frued thin kerf blades on the 12” CMS because the slightest bit of pressure left or right on the trim piece will make the blade “wander”.

This might be why their site says to always clamp the piece when using on a CMS. (http://www.diablotools.com/blades-12.html)

I noticed knotscott said “Full or thin kerf is really up to you. TK offers less strain on the motor, but is more prone to flexing….since crosscutting is easier on the saw than ripping, there’s really less incentive to use a TK for a CMS IMO.” in a previous thread and also that a CMS doesn’t like a hook angle of more than 10degrees, so i’m kinda thinking the fine finish diablo D1280X with normal kerf blade but hook angle of 15 probably isn’t going to be as good as the lu80 with kerf angle of 2 and 96 teeth instead of the 80 teeth of the d1280x.

Should I just wait and order a lu80 because its that much better than the diablo blades I can get at the local big box?

For a 12” blade, I’d definitely stick with full kerf if possible….the wider span will make it even more prone to flexing than a 10” blade….whether Freud or other brand. The LU80 is a terrific blade for ultra fine cuts. The LU85 would also be a good choice for a CMS. The LU80 will tend to have a bit less tearout but will also tend to wear a little faster than the LU85. The 15° hook on the D1280X is steeper than I would like, but could work for you if you’re careful and don’t want to wait.

In general, the Freud Industrial blades have more carbide than their Diablo counterparts, and tend to have more elaborate anti-noise/anti-vibration technology, as well as a wider selection, but the Diablo’s are a good value line. If you really want good bang for the buck, the German made Onsrud blades being clearanced on Ebay can offer amazing values.

I decided to do it right and wait instead of buying the diablo blade.

Last question, whats the advantage/disadvantage to the silver ice coating versus the permashield red coating? The ebay seller with the lu80s in 12” only has the permashield ones for $80 each. Figure most of their blades have this coating so I might as well snatch it up.

+1 for the Onsrud sale. I bought a 10” glue line ripper and a combo $65.00 and free shipping. They are sweet blades. (Well, not that kinda sweet!!!)

I was thinking about getting a 10” glue line ripper for my table saw as well. Maybe i’ll give the onsrud blades a try. trouble is they don’t have buy it now, so I have to wait for the auction to end.

The coating makes them easier to clean, easier to find in the rack ;-), reduces rust, reduces friction, etc…..it’s nice, but I wouldn’t pay much of a premium for it if given a choice. $80 is a good price for a 12” LU80. Good luck!
