Designed primarily for grinding material on an internal cut out, such as an under mount polished sink cut out after the actual hole has been cut. These fit directly to a wet or dry polishing machine and come in a variety of grits and sizes.
30/40 grit - Coarse - For fast stock removal
70/80 grit - Medium - even out the marks from grade one and flattening the surface for polishing
140/180 grit - fine - actually this is almost starting the polishing and is reducing the steps of polishing pad that would be used to finish the surface.
Available in the following three sizes:-
20mm diameter, 42mm deep
50mm diameter, 50mm deep
75mm diameter, 50mm deep.
It's unlikely the two larger size are of interest in tiling, but the finger bit at 20mm, is perfect for opening out holes or edge grinding troublesome shapes.
Being vacuum brazed this will also work on porcelain as well as the usual natural stone products. On stone 30/40 grit is ideal, on porcelain or fine materials the 70/80 is probably a more suitable choice and maybe the 140/180 for fine finishing.
M14 fitment for use on a polisher, will fit angle grinders, but operation at 10,000 rpm might get a bit hairy! Target speed depends on the size of the bit and what you're cutting, but a general rule of thumb would be the larger the bit the slower the rotation. Sub 6,000 rpm is generally recommended.
The holes in the surface of each drum are for centre water fed polishers, these drums are hollow so water can be pumped into the centre and out through the holes.
