20v mitre saw with Diablo blade ?

I’ve ordered the 20v mitre saw and wondered if any of you lot are using a Freud blade in there’s ? I wondered if it performs any better on a Diablo blade as I use Freud blades in my other saws but wondered how it performs in the 20v ? I think a 24 tooth might work well ?

I run a 40t in my 7 1/4″ kobalt slide miter

I would imagine it would do well. I run a 40t and 60t Diablo on my 8.5″ Metabo slider. I’m getting ready to order the 60t Forrest Chopmaster, curious to see how I like it.

Diablo saw blades are the only blades I buy for table saws, circular saws, recip saws and miter saws. 

It comes with a 40 tooth, since it is for cross cutting not ripping the higher tooth count should give smoother cuts.

Quoted for truthery.

What I was asking was because its a cordless saw does it cope ok with a Diablo blade that’s thicker and not designed for a cordless saw ? I put Freud blades in my corded metabo and love them but just wondered if the 20v cuts ok with a thicker Freud blade compared to the thinner one it comes with but I take it it does do

The diablos I have claim better run time for cordless, which blade do you have?

I think that as long as you take your time with the cut and don’t jam the blade into the wood you will be fine. You just won’t get as long of a run time with the thicker blade.

Yeah that’s what I was thinking , the only reason I ask is people keep saying how dewalt blades are not very good so because I haven’t received the saw yet was thinking of ordering a Freud blade as they are always very good

Dewalt blades are decent for construction applications but they don’t compare to Freuds quality. You wont regret buying a Freud. Swap the blades out and hold onto the stock blade just in case.

Personally, I prefer a 60T at minimum on a miter saw and typically run an 80T. Depends on what you’re doing though.

The stock Dewalt blades are made by Avanti which is a Freud product, just a lower grade option. 

You really can’t beat a Diablo blade. Forrest blades are top notch, but they have a top notch price as well.

Making, buying or stealing a zero clearance insert for a miter saw will provide better quality cuts, if you don’t have one can’t make one or can’t buy one just adjust height of blade stops and use a thin sacrificial board

Thats been on my to-do list for a while now

I got this saw and I’m using a 40t Diablo blade. It works great. I was using the Dewalt 40t at first but I was getting too many tearouts while cutting cedar panels. The cuts are a lot cleaner with the Diablo blade. I like Dewalt tools but not their blades. It’s worth getting a Diablo blade in my opinion.

I know my 20v 6 1/2 circular saw runs awesome with a flexvolt battery. It powers through cuts that would bind with a 4.0 or 5.0 battery.

Although I have the 20v miter, I haven’t had the opportunity to try it with the FV battery. I imagine it may do the same. It is a bit slow/underpowered with a 4.0 or 5.0 battery. Now, I’m curious. . .

A FV battery would just increase the runtime. The motor always run at 20V.

That’s interesting because Bosch own Freud so that means that bosch basically supply dewalt there blades !

Upon further reading I’m not sure this information is correct anymore. At one time Avanti was made by Freud. However, it appears Avanti may be owned by HD and produced under contract by someone else. I will research this further and report back.

I am reasonably sure that whoever is making the Avanti blades is the same OEM for the stock Dewalt blades though.

Upon further research, I believe the Avanti blades are indeed still a Freud product.

A 7 1/4 inch miter saw wouldn’t need that high a tooth count to achieve the same results as a 10 or 12 inch miter saw. smaller diameter means smaller circumference which means closer tooth spacing.

Because of the parallel circuitry while running as a 20 volt it may maintain a slightly higher voltage while cutting than a standard battery. Therefor it might maintain RPMs a little better, Think of it like hooking a truck with big 12V battery to jump start a little car with a little dying battery, it will crank faster a whole lot longer, instead of starting to slow down after 10 seconds it will keep spinning fast.

Be that as it may, it has more power.

I can tell you from experience that the FV battery makes the saw run better.

I didn’t expect it to, (“The motor always run (sic) at 20v.”) but it does. I thought it would run the same, but it doesn’t.

Good to know. It’s probably because the high capacity battery has a lower internal resistance. So under a big load, where you draw a lot of current, the voltage start to drop and this happens more significantly with a smaller battery.

You’re right. I didn’t pay any attention that it was a 7-1/4″ saw we were talking about.

The FV battery in the 20v miter saw makes a big difference.

A little higher RPM, perhaps a bit more power.

Nothing quantitative, but it looks like I’ll pick up some FV batteries for full time use on my 20v miter and circular saws.

I noticed right away the increase in power and constant RPM on my 20v miter saw.
