Low wheel speed helps prevent tools from overheating as you sharpen them.

Rikon 80-805 8'' Slow-Speed Bench Grinder

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

Nikon bench grinder attributes
So far very impressed. I retorted a Delta vari-Speed unit of similar size and opted for this. Delta, even at low speed, was too fast (2000 RPM) whereas this unit slower at 1600 RPM. Much better for sharpening chisels etc. Delta also had a wobbly wheel which would have had to be replaced.

Good Value
Well made and the wheels were balance from the factory. Quite operation with good set up instructions. The platforms are a little on the weak side but I’m not using them in my operation.
I would recommend this grinder. It’s a great buy when on sale.

With the white oxide wheels this is a good value grinder. With a small amount of tweaking wheels run true.

Great Slow Speed Grinder!
I'm glad I didn't buy the more expensive, same brand version as this grinder fills the bill. I am a lifelong woodworker and former skilled tradesman and Tech school teacher-this is a well made machine suitable for any non-industrial situation. Runs smooth out of the box!

Well worth the money spent
My main reason for purchasing this grinder is sharpening lathe tools and wood chisels, followed by whatever else needs an edge or reduction. Assembly is very easy. I mounted it to a piece of 2"x8"x28" board (with a 3/4"spacer to accommodate Oneway Wolverine sharpening jigs) so it would be mobile. The grinder with included wheels performed exceptionally well putting very sharp edges on all my tools. I let the wheels do their job and had no issues with over-heating the edges of the tools. No vibration, I did not have to use a clamp or any other device to keep it stationary. Motor is very quiet.

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 own four grinders and my favorite ones are one HP. I have a 3/4HP that bogs down on occasion. The grinder I use most often [ we're talking every half hour or so ] has two CBN wheels attached. 80 and 180 grit. Buy the ones that are wide and have rounded edges.
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.
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.
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
When will it be available ?
