yes this adaptor worls extremely well - also has 2 sizes for the nuts
you can get a large selection of cut off wheels for these grinders - i have had no issues doing this
yes i have changed my nuts to work with porter cable dewalt makita and rockwell the wrench even works with the origional
i have been able to use it on everything i have tried
i have a makita that worked perfect for this wrench
That is what I bought mine for.
YES. It works with my 41/2 inch grinder perfectly
Double check the thread on Makita. It may be metric, not 5/8-11 standard. If the thread is correct, use the new nut with the new wrench; all fit, no worries.
