If you mean 7 1/4” saw blades, they are so cheap that I find it not worth the effort to sharpen them.

Harbor freight has an inexpensive sharpener. I would love somebody on here to try it and let me know how it really works. 12” and 10” blades would be worth the effort in my book.

You can buy a Diamond wheel for your dremel tool.(1 inch diameter, cost her is $2.) I use mine to sharpen my carbide tip blades.

Every review I’ve seen of the HF sharpener is that it’s horrifyingly bad.

Having operated a sharpening service for over 10 years I was interested in looking at the HF machine since a good carbide sharpener costs thousands of dollars and it was about $50.00. Not too impressed. It won’t allow you to sharpened the tops, juist the face. The diamond wheel looks pretty thin and cheap. Might do a bit to help a cheap saw blade but I woudn’t want to use it on a good blade.

Thanks for al the replies, I use a 10” blade in my saw and they are hard to get, I normally buy the Ryoibi blades as they are the cheapest and last for a long time but as I am cutting a lot of recycled timber I hit the occasional nail which dulls the teeth.
The dremel diamond wheel sound like it may work but as I like down under I may not be able to get them here I will check the local hardware

I just leave my saw blade in my table saw and use a very small half inch cut off wheel that is used to cut the ends of nails off a project that sticks out. I mount the cut off wheel to my dermal and sharpen away. I guess I just have an eye for it. I even learned how to use my cut off wheel with my dermal tool to sharpen serrated steak knifes.

Jeff, next time you tackle that job, it would make for a very popular blog.

Jimboy, where do you live where 10” blades are hard to find!? I’ve been using throwaway DeWalts and Diablos, although I have a nice Forrest for the good stuff. I buy a pack of two 40 tooth Dewalts for around $30; one for the ts and the other for the RAS. I would try to sharpen them with a diamond Foredom tool but like David says, for $15, it’s hardly worth the effort. I wouldn’t risk ruining my $100+ Forrest so when the time comes, I’ll send it out to the pros like Garry. I’d imagine the HF is like a giant drill doctor, cool in principle, but too good to be true.

David, I’ve been waiting for a headsup on their bandsaw welder for the same reason!

I am in NZ and the reason these blades are hard to find is that they are a popular size for saw benches and being a small country we get what the retailers bring into the country
Thanks for all your help

a friend of mine bought allot of power shop tools and some of them he hasn’t opened yet since he bought them. one day I was in his shop visiting and noticed he had a electric saw blade sharpener that sharpens table saw blades from 4 inches to 15- 3/4 Diameter. It is a Chicago electric power tool. the motor turns at 3800 RPM while sharpening a saw blade. I am dying to try this tool out. My friend said if I can figure this tool out to show him how as well LOL. Like I said above I use my dermal to sharpen most my stuff but this tool should be fun to try out.

I used to have a saw sharpening service out of my home. Carbide tip blades are easy to sharpen, but you have to have the right machine to do it properly. Doing it by hand with a Dremel doesn’t work. You have to use a machine that can repeatably index each tooth accurately and do face, side and top grinds. Such machines cost over $1000. You are better off sending the blades out to a professional sharpening service. I only do my own blades now.
P.S. If you are cutting through nails, the chances are good that some teeth have gotten chipped beyond sharpening and have to be replaced and that is a whole different ball game.

Thanks MrRon for the info but having blade sharpened in NZ is nearly as dear as buying a new blade this why I am looking at ways to touch up a dull blade

Hi Jimboy, I’m sorry; I didn’t know you were in NZ, but what I said still goes. If you have a steady hand and a diamond sharpener, you might be able to touch up the teeth, but I wouldn’t count on it as being a long term fix. If you can measure the various tooth angles, you might be able to design a jig that can sit on top of your saw that wiill guide a sharpener at the correct angle. Good luck.

I think were seeing or learning the age old argument -re touching up blades ,and sharpenning them.
I don’t and never will accept that a fifty dollar brand new gizmo will make a decent job out of sharpenning good quality blades.I f you have them done locally for say 30 to 50 cents a tooth then that can add up so maybe you need to bite the bullet and buy new every so often.I got my last lot sharpenned here locally from a good saw Dr.Wow he knew what he was doing but some blades were getting costly to do ,so I usually have to buy in new.
Especially when my new saw a wadking cp12 dimension saw can take a sixteen inch blade with around a hundred teeth each. Alistair

Hi there Scotsman I buy new blades when they are available but there never seems to any in stock I think it is because it is a popular size, Dewalt can be bought but are expense and I am told they are no better than the cheaper Ryobi blades that is the same as the Makita expensive

Wow it amazes me how many guys like to talk about sharpening their blades for their table saws and other tools and what you guys talked about. I don’t think I will use my dermal on blades any more as of all the input I got .
