Dunno, but the gent who gave a demo at West Oxfordshire Woodturners this week told us that a member of the club he attends has bought a cheap one from a Chinese seller & all the members are awaiting his feedback.

I bought a cheap one from AliExpress, and it turns out that it's a diamond wheel, no CBN.

I can't remember exactly - around the £30 mark, I think, but as I said, it's not CBN. AliExpress seem to use the terms CBN and diamond interchangeably.

So no good tyvm

No good for HSS, apparently. I'm putting mine in a drawer for 26 years, and then giving it to the wife on our wedding anniversary.

I'd suggest Hope too.

 

[pjwillms]

Thanks for that

I am still using a white wheel that was bought in 1992. I think I will take a look at CBN and dimond as I plan to move to HSS tools
My 1990’s maples are nice to use, takes a reg sharpen when turning hard woods

 

[pjwillms]

Can you get a finer grit in the white wheel

 

[RobNichols]

Two significant advantages of CBN stem from the wheel being metal which means it tends to conduct the heat away so the blade doesn't get as hot as they would with a ceramic wheel, and also they are not prone to break. This means they are less likely to over heat the blade and they are less dangerous to use.

Thanks very much for that advice I will be purchasing one of cbn wheels wood 180 grit be ok.ty
