Tried it this morning.
Not that impressed tbh! With the cutting action being in reverse , the dust collection is amazing . Even better if you put a peice of sacrificial plasterboard underneath. There is no depth adjustment so you need to hang over the edge if something. The machine is very well built.
At first I tried it on an off cut of resin worktop using the supplied segmented blade. It was very good on this and normally this is the dustiest thing to cut.
Then tried a ceramic
tile. From above the
tile chipped out. And from below the
tile was the same.
A grade 5 porcelain
tile was next, again this chipped out massively when cutting from above and below.
I changed the blade to a continuous run ( Ats). These normally cut very smooth. Again on both the ceramic and porcelain, it chipped out too much, but not as much as the segmented blade.
To sum up. For cutting inside the dust collection is fantastic, but as it rotates anti clockwise it sacrifices the quality of the cut.
I will use this for some of my work, but it's an expensive tool for just a few jobs.
The first pics are cutting from above and below with segmented blade and the last two with continuous rim blade from below.
My advise would be don't bother!
