Topic tags/keywords: rikon slow speed grinder

Got a cup of water nearby every time I grind something, and it never stays on the wheel for more than a couple seconds. I know the wheels run slower than my other normal grinder but sometimes I’ve watched videos of people on slow speed grinders (not Rikon) and they grind, grind, grind and never blue the steel, never touch water. That’s simply not the case with mine. Are there slower brands?

I’ve looked into those expensive diamond wheels, do they help (as far as low heat)?

It’s this one, which is fairly popular

I find dressing my wheels regularly helps.

Yeah I don’t know why they run them so fast. I would prefer my slow speed grinder to be a good bit slower too.

For slower, people move to the Tormek and clones.
Like the Fridge, I find that frequent dressing is key to grinding without losing temper (I use a regular high speed grinder).
Not sure, but I think the diamond wheels are mostly for HSS, not regular tool steel. Great for turners, but not so much for planes and chisels.

I usually avoid the heat build up with that exact grinder, by making sure to apply very little pressure. Overall, I lie that grinder.

Thanks Fridge, I’ve got that Wolverine dresser, I’ll try using it more and see if it helps.
Now that I think of it, when I was talking to a guy at a wood shop about the diamond wheel, he was a turner. I never thought about an issue tool steel. Not like I’m gonna buy one soon, they are real pricey.

I got mine off of Ebay and it works well for me.

Same as the Rikon, different paint. Mine too, different brand but identical to the Rikon.

The Cool Grinding Wheels from Lee Valley help with heat build up but do need constant dressing.
I use a hand powered grinding wheel with a Cool Grinding wheel for all my final finish and touch ups, makes a nice hollow grind on chisels and plane irons.

A lot depends on the grinding wheel (maybe more than speed). Fine = heat.

When hollow grinding chisels I don’t even touch the fine stone anymore.
