[Shop-talk] angle grinder spindle adapter

[john niolon]

Hi Mark,   I found the same on Amazon but the internal threads are 1/2-20 and I 
need 1/2-13 so that 
won't work... although the thing on msc site
might do the trick... I wonder if it's 
considered a one time on/off adapter, or would it take multiple on/off cycles 
on the external 
5/8" thread ??  
don't know what the red material on the adapter is..  I'll bookmark that page

I contacted a local tool repair place (Toolsmith)  explained my problem and he found a 6148 spindle (like mine) and he offered to try it in the
6145 grinder if I brought it by to see if it would fit...  he cautioned that the gear drive might be larger for the larger spindle though.  I'm gonna go by
there next week and see what happens

Worst case is that I use the small spindle grinder for disk that are not threaded and use the spindle nut reversed to take up the slack in a 5/8 hole disc
and use the grinder with the 5/8 spindle for the threaded stuff...   It would be nice if everything worked in everything, but that has never happened in my 73 years 
(tomorrow)  on this earth, why should it happen now ???

2020  sheese…  I think I hear thunder... but based on this year... it could be Godzilla !!!!!

Howdy,


Something like this maybe?

I'm not sure what thread pitch a 5/8" 
grinder spindle uses. 

There's not a lot of wall thickness for a 5/8" to 1/2" adapter.  Wouldn't 
surprise me if regular / coarse pitch stuff 
wouldn't have enough wall thickness for an adapter to work?

It does look like there' 
some type of thread repair thing for those pitches though:

my 5/8" accessories are threaded

Doesn't the grinder already have a...uh...uh...thing that if you flip it 
over it's got a 5/8in boss on it to center the wheel?

I have never encountered an angle grinder that didn't have a centering 
thing for a 5/8in wheel no matter the shaft size.
