Not sure if this fits better here or the MT.
Need to do some touchup install for a metal roof and some cement board siding, and was wondering if anyone has had luck / tried cutting 26gauge metal roofing panels/shingles with the KSS60. I'm less worried about the power of the saw, more of if anyone has had issues with the metal shavings / cement getting everywhere and ruining the saw. I know Maffell makes a cement board blade, but, cement is awful to cut and I hate it.

Used a continuous rim diamond blade to cut 12mm (1/2") Hardieflex type fibre cement sheet with a Metabo Plunge/Pendulum saw (KSE 55 Vario Plus). 160mm saw, 125 or 150mm diamond blade.
Slow, extremely messy, & yes, it gunked up the remote pendulum cover retraction lever mechanism. Needed a good blowout with air, a strip & clean with a toothbrush & (I think) Kerosene?? Still wasn't perfect afterwards until all moving parts were substantially re-lubed.
Summary: not worth the hassle.
Worse-case scenario: a steel/aluminium flake gets sucked into the cooling intake & fuses the motor. Unlikely, I know, but I 'effed up a really nice electronic 80's vintage power drill with a wire brush in this exact manner! Fused the mini-computer onboard, not the field or armature, but the result (expense) was the same.
What about a corded mini-grinder either in a dust-extracted track carriage or freehand like everyone else does? This is what they're designed for.

a dust-extracted track carriage or freehand huntsgemein , do you mean use a track saw (MT55) that has great collection, or a dust carraige around a grinder?
And, because I hate those stupid metal chips & dust flying eeeeeeeverywhere. Not only do I loathe cleaning them up, but I'd like to reduce the amount just spraying everywhere. (Still very much intend to use PPE), but not having a spray of metal / dust while cutting would sure be nice.

You could theoretically use either, with metal cutting blades, but I'd choose the grinder every time. There's semi-enclosed extraction guides available from some manufacturers. Usually only suited to corded grinders. Metabo's only fits the "older generation" guide rails, not the newer Bosch/Mafell compatible series, but has 4 tiny wheels/rollers on the base for wall & floor chasing etc, variable depth of cut & a decent extraction hood & spout. www.metabo.com/com/en/accessories/cutting-grinding/further-accessories-for-angle-grinders/extraction-hoods/cutting-extraction-hood-ced-125-plus-626731000.html?listtype=search&searchparam=ced%2B125%2BplusMaybe someday Metabo might actually release one that fits their latest guide rails, but don't hold your breath. Hopeless, I know! You'll still need to follow your cut markings freehand by eye. Most quality Euro manufacturers make at least crude but effective steel extracted guides for similar cutting & slitting purposes. You can get relatively inexpensive 125 mm steel cutting blades, often with a 25 mm arbor hole & washers in 22.24 & 20 mm sizes to fit a variety of different saws/tools. Alternately, an Arbortech "Tuffcut" (now renamed "Trade Blade") is a 115 mm all-purpose super-duty saw that still offers a reasonable depth of cut (20-25 mm +/-) in a 125 mm grinder. I can personally endorse these as a somewhat dangerous but nevertheless remarkably effective all purpose freehand cutting tool for most mini-grinders. This solution will (I guarantee) be super-messy & is only suitable for non-ferrous metals. www.amazon.com/Arbortech-IND-FG-115-Woodworking-Tuff-Cut/dp/B008ACZ86G
