Will watch the video soon with interest. Need a few more drills, but after reading the previous comments I have just bought a good handful of 7-8 ATS sizes for about £36 or so. Looking forward to seeing how they perform. My current
Tile Rite cutters have lasted long beyond my expectations and still have a bit left in them.
Keep testing lads, it's really interesting to see how things perform in real life rather than what it says on a packet. The trowel/glass test will be one to watch, to see if a true "solid bed" can ever be completely achieved.
