Product Information:

The Rikon model 80-805 Slow Speed Grinder features a smooth starting, powerful ½ HP motor. The grinder operates at 1,750 RPM, which is ideal for sharpening operations because it reduces heat build-up and minimizes the possibility for “bluing.” This grinder comes equipped with two 1" x 8" white aluminum oxide grinding wheels: one 120-grit wheel and one 60-grit wheel. The cast-iron base features anti-vibration rubber feet and is equipped with mounting holes for convenient attachment to a workbench or grinder stand. Grinder comes with Tool Rests, Eye Shields, Spark Arrestors, 6' Power Cord And Five-Year Warranty.

Comments about Rikon 8in Slow Speed Grinder :

Like most people who will buy this grinder, I use it to sharpen HSS turning tools. It's by far the best value on the market for this application. As a number of viewers have noted, the relatively inexpensive wheels supplied with this grinder are not perfect, but users with access to a web browser can find very good, clear instructions about grinder set up to remove almost all of the imbalance from most wheels. Mine runs with no discernible vibration at speed. In most casese of excessive vibration on any grinder, it's a set-up problem and a wheel problem and has nothing to do with the grinder per se.

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.

Excellent Value

Best Uses

  • Sharpening

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!

By  Tool and die man

About Me Professional

Pros

  • Easy To Use
  • Ergonomic Design
  • Quiet
  • Smooth Running

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.

  • Shaping/Finishing

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.
