Hi everyone, Just wondering how the 18v fairs for power against the 240v? Not many videos atound for the kss60 18v.
I cut a lot of 300x45mm Blackbutt hardwood and LVL's, will I be disappointed with the power if I go for the 18v and wish id bought the 240v?
Would be nice to be cordless but if the 240v is way more powerful that would probably sway me to a cable.
Thanks all!

I don't have the 230v, only the 18v KSS60 - it's a decent saw and fairly powerful.
My only comparison where I have both is the MT55, and the 230v is more powerful than the 18v - but I wouldn't say 'way' more powerful.
As you're talking about '240v' I guess you are in the UK?.. speak to NMA (or even your local dealer), they may be able to let you try both.
Personally I think the KSS saws lend themselves to being cordless. Let us know what you end up getting!

I'm in Australia, but ordering from UK or Netherland.
There's no stockists in Australia so it's always a bit of a leap of faith getting a Mafell tool, no way to try it out first and a lot money if it's not up to the job.
Very tempted to play it safe and get the corded, would love the cordless though.

(Don't have KS60) I'd "guess" blackbutt is easier to work with than Sapele, corded MT55cc (1300w) with 24 or 36 teeth blade only just manages to cut 40mm stock. We don't get Blackbutt over here, but going by a bigger saw I think cordless would be OK, however batteries- you'd need 3 or 4 or maybe even 5 for a reasonable days work laying floors... My $0.02ct on your dilema

Blackbutt is just over 50% harder than sepele, going by the Janka scale 9.1kn to 6kn, it is very hard. I cut it with my mt55 240v, and I wouldn't want the saw any less powerful.

If you don't want it less powerful than the MT55 230v - you'd be better off going with the corded saw - 1800w plus variable speed.
The power issue is overcome with thinner blades on the 18v - 1,8mm instead of 2,4mm. See what blades you can get in 185mm where you are.

theartificer PM'ed you with suggestion, as not sure how FB links would be taken by other members...

I recently got a KSS60 18V. Haven't had much chance to play, but it cut 20mm thick old Jarrah (8.5kN) pailings like butter (Metabo 8.0Ah battery). I'd love to test a full depth cut for you, but I don't have any 60mm thick bits of Jarrah.
I'm not sure if the thin kerf blade is so much about power as it is about battery life these days (less wood volume removed = less discharge). Certainly with brushless motors and high discharge current batteries, I don't think there is a shortage of power.
Metabo claim their 18V batteries can deliver 3200W peak. Even at only half that it's still a powerful proposition (provided the tool will draw it).

For full depth cuts. the 5,5ahs have a higher output in amps per minute or however it is measured... also cheaper than the 8's and 10's. Definitely the sweet spot.

The 4Ah are single row batteries (all cells in series). The 5.5Ah, 8Ah and 10Ah are double row (two sets of cells as above, in parallel)
Each row can deliver the same current, so a double row battery should be capable (theoretically, in an ideal world, all else being equal, etc.) of delivering twice the current (and therefore torque and power @ the tool) of a single row battery using the same cells. Provided that the tool can draw that current.
In Australia, at least, the 8Ah battery wins on a price/capacity ($/Ah) basis.

Yes but all things aren't equal, the 5,5's are better for high drain tools. I can't remember the figures, had the Metabo rep in last week, he explained the differences. It's not just about runtime, there is also the amount of amps that can be delivered per minute, and the 5,5's win.
