As a bathroom designer and installer I have a great deal of time for Bosch equipment generally. However, the description of this as a Tiling set should be reviewed. Only HALF (2) of the items are specifically for use with tiles, one is a metal cutting blade (!?!?) and the other is a general purpose scraper.
If you are looking for specifically tile cutting 'blades' then you going to be further disappointed as one of the tile tools is for shaping the edges of tiles not cutting.
In my view, if you require tile or grout removal capability then you are best off buying the RIFF sawblade ONLY. As a tiling 'set' this does not represent good value for money as stricty speaking you only get ONE tiling blade. In my view, although more expensive individually, you get better value as you're not wasting it on stuff you do not need.
