Anyway it it sounds like it’s 5/8” by what PFH says. I’ve got quite a few Freud blades in 5/8”x10”(254mm) myself and I’m happy with them

My tablesaw also has a 5/8 arbour and I haven't had any trouble finding suitable blades (and fortunately reducing inserts work fine on my saw as long as they are NOT 16mm )

I'd be inclined to agree with that given that we're talking about 0.125mm, the thickness of an average piece of paper

but then again you never know the americans

I'm not sure if you're meaning that the 0.125mm difference doesn't matter, but it certainly does. That's 5 thou" and I'd be sure that that would create vibration at 4800rpm, which would lead to rough cuts....or worse. Conversely a 5/8" blade just would not go on a 16mm spindle.

no its not what I meant

I'm thinking the the dewalt engineers may not go to the trouble of having 2 different shaft sizes for such a small margin for different countries

This is a shot of the blade from the new saw,note the bore size, I've noticed a lot of the blades from some suppliers also have 5/8" (16mm) marked on them, in particular DW ones

Yeah, agreed. It's just Americans not really understanding metric I suppose - they definitely wouldn't have the two sizes.

I came across a curious reversal of this recently, buying Gühring drill bits which can be had in 0.1mm increments. When it comes to their Imperial sizes they sometimes round down the metric instead of just rounding – 1/8" is 3.175mm so they call it 3.17 rather than 3.18 which is the convention for rounding a 5 (up).

All of this just goes to show what a hideous system Imperial is for 98% of things. Don't get me started on the Letter Drill sizes or the Wire Gauge Drill sizes.....

You might want to sell your dewalt

here's a couple of shots, the shaft size is 14.17mm and the blade bore size is 15.86mm, without the nut done up you can move the blade up and down on the shaft , so much for precision

cheers

And that's why you got it for the price you did

Nice one Dallas lol maybe it was a factory second, or one that was assembled on friday arvo

Au contraire. You might want (try) to sell yours!

That's 2 thou difference, not allowing for the vernier rounding to the nearest 0.05mm (2 thou).

That's 1.7mm difference - there must be an annulus or something on the inside of the flange to centre it, or it will vibrate the shed down. Or is there a ring to insert into the blade? Or a bush to put over the spindle? That is just not kosher at all.

Wait a sec....did you measure the threaded part of the spindle or right on the bush that the blade sits on?

well 1st impressions are good after a few test cuts

the motor seems to have braking of some kind, it doesn't seem to take long to stop

the fence with r&p is excellent and very accurate although it seems to be not quite square vertically although its very minimal, I can probably use shims to get it perfect in time

the blade and fence needed no adjustment out of the box as did the riving knife alignment thankfully, its in a hard to access spot

if you use the drop down fence to make ripping low profile timber easier, or use the fence to the left ,the measurement scales dont relate (i'll probably get out of that habit anyway)

some reports say its a bit noisy, doesn't seem to be, maybe I'm used to the old triton 2000

I'm still looking for a fine cut blade maybe 60t, any recommendations appreciated

cheers

right on the unthreaded shaft as close to the back plate as possible

as I said I could move the blade up and down a tad with the nut finger tight

doesn't seem to vibrate at all, very smooth

measured it again, you are right I must measured it a bit on the flat part first up
