I found the DSC-AGC 18 manual on the UK site and confirmed the tool is not intended for the following uses or with these accessories/attachments. This list is not all inclusive, you should read the manual.
- Do not attach a saw chain, woodcarving blade, or toothed saw blade. Such blades create frequent kickback and loss of control.
- Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.
- Operations such as grinding, sanding, wire brushing, polishing or cutting-off are not recommended to be performed with this power tool.
- This power tool is designed to be used as an abrasive cutting machine.
So it looks like you are limited to dry cutting of masonry/cement/tile/engineered quartz, etc. No surface grinding of these materials is allowed with this tool.
No cutting of metal using cold cut (toothed) blades, abrasive cutting only = lots of sparks but a spark trap is no longer available from Festool.
The DSC-AGC 18 can not be used for sanding or grinding are verboten per the manual. There is nothing that I saw in the manual that says otherwise or if you get conversion kit xxx for an additional $$$ you are OK to do surface grinding and sanding.
So does that mean you need to buy the AGC-18 to do surface grinding or that you have to buy the proper guards and other kit to use the DSC-AGC 18 for grinding and sanding. I ask because underneath the two tools seem identical and it's only the guard/attachments that differentiate them from one another.
Which (if at all) should/can I use for tuck pointing. If I need to cut out mortar joints is either tool acceptable for this use and if so with what accessories.
When I look at the Makita XAG17ZU which is also a 125mm/5" variable speed (3000-8500 RPM) grinder I can get accessories to do the job of both the AGC-18 and the DSC-AGC 18 and it also has BT capability to communicate with their 36v cordless HEPA Vac. The Makita grinder plus a pair of 5AH batteries is about $350, the cordless HEPA vac (which can also be powered from the mains as a corded tool) with a dual battery charger and a pair of 5AH batteries is another ~$825.
