Low wheel speed helps prevent tools from overheating as you sharpen them.
Item #
86% of 100

Woodworkers looking for a bench grinder that's capable of putting a sharp edge on chisels, plane irons, turning tools, knives and other hand tools will be delighted with the Rikon 80-805 Slow-Speed Grinder. Hit the power switch, and it starts up smoothly and quietly, coming up to speed at only 1,750 RPM, a low speed that all but eliminates the risk of tool damage from excess heat. For very damaged edges, we recommend dipping your tools in a water bath periodically as you sharpen. Two wheels—60-grit and 120-grit—let you go from rough grinding and shaping to final sharpening without any changes or setups. The left tool rest even features a V-channel for sharpening drill bits. At this price point, the Rikon 80-805 represents a very economical sharpening system that will give you sharp tools in a very short time. Of course, you can also use it for light-duty grinding or rust and paint removal with great success.


  • Cast iron base and rubber feet contribute to a solid feel and reduced vibration
  • Both wheels are surrounded by heavy-duty spark arrestors
  • Individually adjustable eye shields help to protect your face and eyes
  • Dual tool rests let you position your tool at a variety of angles
  • Left-hand tool rest has a V-groove for sharpening drill bits
  • Includes diamond wheel dresser for keeping the wheels round and flat

Great grinder
I needed a slow speed grinder for my lathe tools and this was the perfect balance of performance and cost for me. Even without the CBN wheels I am hoping to add in the near future, this grinder has made my sharpening process a lot smoother. I paired it with the Pro Grind Sharpening System and it works great for my lathe tools. If you do mount with a sharpening system, the wheels are very low, so be sure to add extra height under the base when you do mount it.

Great grinder. Perfect for honing turning tools. Works great right out of box. First one shipped was damaged. It was a great price at $99. Don't know why it's up to $139. Bought Wolverine jig with it.

BEST ANSWER: Read the fine print, “ Excludes sale items”
Oneway recommends standard 3450 rpm speed for their Wolverine jig, is this "slow-speed" grinder going to be a problem for that jig?
David A on Sep 1, 2016
BEST ANSWER: I've not had my setup long but i use my wolverine jig with this grinder. I haven't used the wolverine jig on higher speed machines so i have no basis of comparison however i find that even though it is a "slow speed" I have to be careful to not remove too much material when sharpening. I don't think i would want a grinder to go much faster. I use a lot of smaller tools 1/4, 3/8, and 1/2 this may be a factor.
Has anyone wished they would have bought the 1 HP model instead?
I'll I plan to use this for is sharpening lathe tools and MAYBE a chisel or two down the line.
Chris C on Dec 17, 2017
BEST ANSWER: I have used it a little for knife sharpening and it performed well
I use it mainly for deburing metal after cutting and hole drilling

Wood carving gauge sharpening?
Shailesh S on Jun 7, 2020
BEST ANSWER: If you require a razor edge on your carving tools then this will not work as the wheels that come with the grinder are too course. You could add a 600 grit CBN wheel (item #66307) for a smoother cut.

Better still consider a wet sharpening system such as the Rikon 82-100 8'' Wet Sharpener (item #55683). The alternative if you wish to sharpen by hand would be traditional wet stones.

what side should I use to sharpen turning tools. 60 grit or 120 ?
Joseph on Nov 3, 2019
BEST ANSWER: I use the 60 for roughing gouges, scrapers and for reshaping detail gouges and skews, I use the 120 for final and the 120 to finish reshaping tools and sharpening detail gouges, parting tools, and skews before finishing with a diamond hone,
Can you attach a water bath?
Steve on Nov 1, 2018
BEST ANSWER: The low speed is supposed to ensue that a water path is not necessary. If you are worried about over heating Rockler suggests inserting the tool in separate water bath. Overheating has not been a problem for as I use M2 steel powdered metal tools from Crown.
Can this be used for sharpening lawn care tools and mower blades?
Allen F on Jun 4, 2018
BEST ANSWER: Only if they’re not too dull; in general, blunt steel is more quickly sharpened w/ a conventional high-speed grinder but there’s a danger of ‘blueing’ the blade due to high heat. This will ruin the temper of the steel & cause the steel to become brittle & lose the edge quicker. This can be somewhat avoided by cooling the edge w/ water occasionally.
Hello and would this device work on putting an edge on a Straight Razor used for Shaving.The angle is what I am concerned about. I do it now with 4000/8000 wet stones and for a final edge a 12,000 stone.But it's Very Time Consuming and was wondering if this machine would take away the first steps of honing the straight razor the completing it with just the 12,000 Wetstone. Let me know your thoughts?
Thank You,
Jpc15045 on Sep 25, 2016
BEST ANSWER: That is not the machine for you. I like a 2" belt sander with very fine sand paper like up to 12,000
Can this machine accept buffing/polishing wheels as well? Is the speed appropriate for those raajs?
Edward on Jun 14, 2018
BEST ANSWER: I see no reason why this grinder could not be used with a wire wheel or buffer. I think the speed is adequate for both processes but buffing would be more efficient with a 3450 rpm unit. For thin wire wheels the guards should stay intact but when used as a buffer I would remove the guards so that more of the buffing wheel is exposed. Small buffers are not equiped with guards because the wheels are made from cloth and not very dangerous.
can I mount a 1 1/2" wide CBN wheel on this lathe?
Jim M on Jun 8, 2020
BEST ANSWER: I know the 1 1/2" wheel will fit on the 1 Hp Rikon slow speed grinder but I'm not sure if the arbor on the 1/2 Hp is long enough.
