'Ruby' Grinding Wheels
for High Speed Grinders

For the ultimate edge, why not re-equip your grinder with the ultimate grinding wheel. Most turners today realise that sharpening their High Speed Steel (HSS - as sold on this site) tools on a traditional grey grinding wheel is asking for trouble with shortened wheel life and an overheated cutting edge. The newer 'breed' of Aluminium Oxide wheels, often known as 'white wheels' for obvious reasons, has been the favoured solution to this problem for some years now. These wheels give improved results with HSS tools because their grit is sharper than that of the older-style grey wheels.

Now at last, sharpening guru and innovative turner Mick O'Donnell has come up with the ultimate fast, cool-cutting 'Ruby' grinding wheels. These wheels are sharper than either grey, white, or even pink aluminium oxide wheels and keep their shape better than any of these, including white wheels. (But see the notes on our blue ceramic wheels, below)

Sharper grains mean faster cutting - faster cutting means less heat build-up, reducing the risk of drawing the temper of the steel and giving a really fine edge to all of your tools.

Don't you and your tools deserve the best?

These wheels are selectively available in 6" and 8" diameters, 3/4", 1" or 40 mm (6" only) width and in a choice of grits. For initial heavy tool shaping, a coarser, 46-grit, wheel is recommended, whilst for routine sharpening and maintenance of a fine edge, an 80-grit version is available. Perhaps you should show how 'sharp' you really are when presented with an opportunity like this - why not fit one of each 46-grit and 80-grit, if you have a double-ended grinder - and enjoy the best of both worlds. Note the availability of 40 mm wheels to replace the white wheels used on some Creusen grinders and the special, depressed centre wheels which allow you to upgrade a 3/4" grinder to 1" wheels.

Blue Ceramic Grinding Wheels

If you thought that the only blue ceramic was Delft ware, then you are about to be proved wrong. Just when we thought that Ruby wheels had resolved all of the problems we would ever face with regard to sharpening, the guru of sharpening, Mick O'Donnell, has come up with another giant leap forward - the ceramic grinding wheel, which is differentiated by its pale blue colour.

What is different about this wheel - colour apart? Firstly, it cuts even faster than the Ruby wheels and yet produces less heat thanks to its grit bonding characteristics. So much so, in fact, that we are only supplying this wheel in a 100 grit grade. My personal view is that even this grit cuts faster than a Ruby wheel: it is a real metal-eater and is perhaps not to be recommended to beginners or the heavy-handed. However, if you are a competent turner or maybe into producing your own radical grinds and reshaping tools, then one of these wheels could well be a great addition to your workshop.

Because of the somewhat specialised nature of these wheels, they are only produced in one size, which is 3/4" (20mm) wide and 6" (150mm) diameter, 100 grit. The centre bushing can be provided to suit your grinder spindle, as for the Ruby wheels.

So, if you need the very best performance from your grinder, and if you have the experience to handle it - or are prepared to work with due care, then this could be the wheel for you. Thanks, Mick, for another great leap forward in sharpening technology.
