20mm arbor angle grinder

[mistral]

Anybody come across an angle grinder that has a 20mm arbor as opposed to the usual 22mm one? I came across some diamond blades when I was in East Asia that are 105mm with a 20mm centre - I just wonder what they're used in.

Absolutely no idea

Arbor, thats for a guiding hole:ninja:

While working in Australia my Bosch (blue) grinder used a 100mm wheel ( actually about 105mm) and had a smaller arbour about 16mm i think. I used DTA wheels, readily available in "Bunnings" ( Oz equivilant of B&Q) and they came with bushes for different arbours.
I have seen 105mm wheels over here but not many.

Yes, these are 105 x 20mm and there is a ring adapter to sleeve it down to 16mm.

Just change your grinder, get a Makita and no more problems. Its not worth the hassle.

Strangely enough these are makita blades! Maybe they're made for the antipodean market.
Cheers anyway.

All my grinders, including my two Makitas have 22mm arbours because all blades in the UK have 22mm centre bores. I've bought high quality glass cutting discs from Asia and they are 20mm bores, yet there seems to be no conversion kit on the market!!
