holesaws
A hole saw (also styled holesaw), also known as a hole cutter, is a saw blade of annular (ring) shape, whose annular kerf creates a hole in the workpiece without having to cut up the core material. It is used in a drill. Hole saws typically have a pilot drill bit (arbor) at their center to keep the saw teeth from walking. The fact that a hole saw creates the hole without needing to cut up the core often makes it preferable to twist drills or spade drills for relatively large holes (especially those larger than 25 millimetres (1.0 inch)). The same hole can be made faster and using less power.
The depth to which a hole saw can cut is limited by the depth of its cup-like shape. Most hole saws have a fairly short aspect ratio of diameter to depth, and they are used to cut through relatively thin workpieces. However, longer aspect ratios are available for applications that warrant them.
Cutting with a hole saw is analogous to some machining operations, called trepanning in the trade, that swing a cutter analogous to a fly cutter in order to achieve a similar result of annular kerf and intact core.
After four hours of driving from London we reached Preston.

Bought an 8mm wax filled diamond drill for 23 quid a few months ago. I can confirm the claim that they drill 50 holes so if you do a lot of bathromm work with these modern hard tiles/ porceliens theyu are just the job. Local tile supplier sells the but I can't remember the manufacturer.
Sorry...
