Comments about Rikon 8in Slow Speed Grinder :

I bought this grinder earlier this year on a similar sale when I was setting up my turning shop, and it's a great deal. Just having the friable grinding wheels on it makes it worth the cost. It's quiet, there's minimal wobble, and it does a great job of sharpening and re-profiling lathe tools.

Comments about Rikon 8in Slow Speed Grinder :

I use this grinder to sharpen lathe tools. It's the least expensive slow speed ginder I could find. Biggest issue is both wheells have a noticeable wobble and cause the grinder to vibrate. I've spent hours trying to get them to run true. I think if I had it to do over again I'd spend more for a better machine.

works well. Best you can get for the price. I have sharpened chisels, plane blades and I'm a wood turner too, so it gets used quite a bit.

Comments about Rikon 8in Slow Speed Grinder :

I use a grinder primarily to sharpen lathe tools. I bought this to replace my old 8" high speed grinder, and it certainly does. The slower speed gives me much greater control over the tools, the temperature is lower and more manageable, and the grinder comes with white wheels of two different grits. The tool rests are adequate, and the left-hand one has a slot for sharpening drill bits. I have installed, though, an aftermarket platform (larger) and a support for a "Vari-Grind" jig for sharpening lathe gouges. The grinder even comes with a diamond dresser. There are two problems with this grinder. First and most obvious, it has no light. That's not a big deal for me because I already have a magnetic shop light that I attach to the side, but for someone who doesn't already have one, it's an extra cost. And you really need a light while sharpening. Second, there's a noticable side-to-side wobble in both wheels. You can dress the wheels to take out the problem along the rim, but there's still a vibration that is irritating and makes it a bit harder to keep control while sharpening. I'll take the wheels off in the near future to see if I can shim them, but it shouldn't be necessary to do this. Fix these two problems, and you'd have an excellent sharpener.

Comments about Rikon 8in Slow Speed Grinder :

The unit I received is smooth and quiet. I use a Wolverine Sharpening System so I never installed the tool rests. Wheels are adequate for now and when they wear down I will replace them with Norton wheels. All and all a good buying experience and a great value.

Not a low speed grinder!

Cons

  • A Slow Speed Grinder Runs
  • At 500 Rpm

Best Uses

  • Cutting

Comments about Rikon 8in Slow Speed Grinder :

As stated above, a slow speed grinder runs at or below 500 rpm, not 1750 rpm. This grinder will easily take the temper out of tools if you're not careful.

Comments about Rikon 8in Slow Speed Grinder :

I started turning pens, and quickly found out 2 things. 1) I have to keep the tools sharp or bad things happen, 2) My old 6 inch grinder sometimes does more damage than good. I took advantage of a sale price on this grinder, and am very happy with it. You can overheat tools when sharpening, but you have to work at it,and it leaves a very smooth finish. When I got the grinder, it was missing the knobs to tighten the tool rests. I emailed Rikon, and after they verified the part number, I got 2 knobs in the mail, no hassles. Slight side to side wobble on the wheels, but the cutting edge was perfect.

Comments about Rikon 8in Slow Speed Grinder :

I am a wood turner and needed to replace my grinding wheels for my 6 inch grinder. I had wanted to upgrade my grinder to an 8 inch and this grinder was just came on the market. The $99 price was about $20 more than the price of two new wheels so I bought this model because it is larger AND it came with the wheels I was looking for. GREAT deal and flawless performance.

Comments about Rikon 8in Slow Speed Grinder :

I got this grinder to sharpen lathe tools and hand tools for woodworking. I had been doing some research on slow speed 8" grinders when this one came up for sale so I decided to get one. I was very impressed with the weight of the grinder, how quiet it runs and that it has all metal parts. It comes with rubber feet attached so it can just set on your bench or you can remove them and mount it. I'd read about grinders vibrating so bad that they danced across the bench so I was pleasently surprised when I turned this one on and it ran relatively smooth. Just a little vibration in the left side wheel which should dress out. I will probably not even mount this to a bench. One thing I was surprised to get was a wheel dressing tool. The write-up didn't mention one was included so that was a plus. The only negative was that my grinder came with two right-side tool rests and no left-side rest (which is the one with the drill bit guide). I emailed Rikon Customer Service telling them about it. Within 4 minutes I had an email back from them telling me I had a new left-side tool rest on the way. You can't ask for any better service than that.
