Wondering which Bench Grinder is Best.

I’ve really been enjoying my lathe lately, and I “Accidentally” sharpened my Skew to a really sharp edge and guess what – I finally discovered that Sharp tools do work better with Lathe Tools :-). The quality of the cut is really smooth, required only minimal sanding. I ordered the Wolverine Sharpening system, with the the Vari Grind jig and the Raptor Angle gauges. The system works extremely well.

Now, the problem is the Bench Grinder that I currently have – it’s a 6” 3650 rpm grinder. It does sharpen the tools and with the Wolverine system – the sharpness is amazing. I am wondering if I would be better off with an 8” 1760 rpm grinder. It seems that it would be less aggressive and create less heat on the tool. What do you guys, or gals, think about this? What brand is best – in the $150 or so range?

I will really appreciate any suggestions or thoughts.

I believe the 8” slow grinder would be a wise investment. Make sure on wheel is as fine as you can get. The other, I would think, should be somewhere between course and fine. Look into fixtures/jigs for use with the 8”.

I’ve been working on one for a while now and still not happy with my results. Saving money isn’t always the answer.

Keep the old 6” for course work and rough shaping.

Check out some online videos on sharping.

I purchased the Woodcraft 8” slow speed grinder (1720 rpm) and have never regretted it. I am very happy with it and would never go back to the 3650 rpm grinder that I had used previously. The slow speed grinder is far better for sharpening lathe tools in my opinion. I also purchased 2 Norton replacement discs for the grinder as well which are great. The Norton discs were more true than the stock discs that came with the grinder. One of the stock discs had a noticeable wobble. I also have the Wolverine system and found that to be indispensable for sharpening lathe tools. Good luck!

Don’t know how you feel about Grizzly Products Bill, I bought the T10097 8’’ wet grinder ( $90) few years ago in a pinch and has served me well. I don’t have any store bought sharpening jigs and do most of my sharpening free hand and get good results. Just my 2 cents.

I’ll second Tigo’s recommendation. Woodcraft’s 8 incher is set up for my Wolverine as well, and it is sweet. Funny, they don’t seem to list it as an item on their website unless I’m missing something, butI was in Woodcraft not 3 days ago and there were 2 sitting there. Maybe they are phasing them out and you can only get them in a brick and mortar store.

I recently bought the Porter Cable 8” grinder. It is variable speed. I’m not sure how slow it goes since I run it on “11”. I was thinking it would be ideal for lathe tools, though.

Slower is better so you don’t heat up those fine gouges too much

Thanks all for the comments. I think that I will go with the Porta Cable 8” variable speed grinder. It’s available at Lowes for $119.

Hi Cajunpen,

Not sure if you’re still keeping track of this thread. I’m a relatively new woodworker and I am currently looking to get a bench grinder for my tools as well. The more I read reviews the more confused I become as to which is the right model to buy! :) I was wondering if you bought the Porta Cable 8” model and how you like it?

Thanks for your time!

Dan, I actually ordered the Wolverine sharpening and was shopping for a low speed grinder. I discovered the Easy Wood Tools and sent the Wolverine back to purchase the EWT set. Now I don’t worry about sharpening. I find turning with the EWT tools fun and rewarding. Hope this helps you.
