In this woodworking deep dive video we look at how a saw blade is sharpened. Last week we discussed how to tell if your blades were dull and this week we’re going to take a look at how the saw shop cleans, inspects, fixes and sharpens your blades. This was amazing to see in person and I certainly learned a lot more about the process. We also got to see how they make spiral router bits and drill bits. Let me know what you’d like to see next. Thanks for watching! Please like, comment and subscribe. Cheers!

Well if my memory is correct, 0,001mm = 1 micron - Amazing accuracy!
I am far from an expert in metric. I model in metric on the computer so that's really good to know.
Most honest guy I know!!!
Love seeing this. As a manager of small to large machine shops for the last 30 years I have had probably millions of blades and tools sharpened. Last Shop had an Anca tool grinder to reprofile tools for our aggressive high speed machining we did. managing tool life and knowing when cutters would die we were able to get 4 custom grinds on the inner face before they were used up.
I sharpened blades many years ago , cleaning was a bucket of water and Mr Clean, worked good
I've been a Diablo user for quite a while, figuring that they were good enough for the price. After this video, I went on Taylor Toolworks to check out the CMT blades. Found that the ITK Orange were on sale, so took the plunge ordering the 24, 42 & 60 tooth blades. Man, what a difference. Quality is evident down to the packaging. Looking forward to using them more.
I really appreciate all of the info you present and tool reviews. I've bought several from you and your recommendations. - Chris
Just ordered all 3 of the blades you recommended on Sunday and got the email Monday morning saying they've been shipped. Thanks for the 10% discount code. 3 blades and free shipping only $178
I'm in Bakersfield so I'm just a short distance away. Going to give them a try with a couple blades I have
Good old Buckersfield! I’m not far from there myself.
Wicked cool video dropping some awesome knowledge. I appreciate the depth you’ve been getting into. I had a lot to learn when I started last year (still do). The majority of my woodworking playlist is your videos. I reference the tool tune up videos all the time. Jointer video saved my 8/4 walnut last week. Anyways, thanks for the excellent content!
Great episode; just love seeing incredible craftspeople who are skilled at their jobs!
Another great information-packed video Jonathan! Thanks for keeping us learning.
just ordered all three blades that you use. thank you for the discount code! excite to test those blades!
you have very high quality videos for such a small channel, some people who have 1+ million subscribers don't even have quality such as good as your, maybe its the camera and background mixed with the way you speak 👍
Super interesting and so high tech.......loved the tour!
Great video! It's cool to see what they can do. I have loved CMT blades and bits for a long while. I live in Edmonton Alberta and we have a similar place called All blades. They sharpen anything and even make bandsaw blades to any custom size.
Amazing vidieo! Need more of this type. Who knew so much was involved in blade. Well, looks like I bought my last diablo! Would love to see more videos of this sort, such as your chisel sharpening one.
Wow this is just cool. Those machines are just awesome.
Worth watching.... Loved it..
This was awesome to see. Thanks for setting it up and showing us. Makes me feel good about my cry once blade purchase😉
Beautiful
Thank you Jonathan! I love machinery like that; the accuracy they are able to achieve is amazing. Makes me wish I was closer to CA. I’ll have to find someone here on the East Coast that can do that level of machining. I got a CMT miter saw blade and a dedicated rip blade for the table saw. Both of them are great blades! Really happy with CMT blades. Thank you for the discount. And, thank you for the information!
Hi Sandy. We can handle your sharpening if you are willing to send it. USPS flat rate packages are an economical way to send out here. You just have to be careful to package them so they don't move around in the box or touch the other blades. We will pay return shipping on 4 or more sawblades.
Got my new CMT Rip blade a couple of days ago, and it's impressive (got the discount, thank you)! So far ripping hickory like sticks of butter!
awesome video! I had no idea.
Interesting look into this process. Thanks for sharing!
amazing video... I always wonder how they sharpen blades.. my neighbor told me he wanted to know they do it. now I can share this video to him. 😊😊😊
Amazing information.
Impressive!! Thank you !
Damn... to fast with the return button. I would love it if you were invited by one of your employees to make something out of pieces of wood lying around. Of which you do not know dimensions, have no idea which wood etc.
That's awesome thanks for the video
Impressive.
Lovely
Great video!
Pretty amazing, Jonathan! They really do a fantastic work! 😃
Thanks a lot for sharing!!!
Stay safe there with your family! 🖖😊
So Jonathan what would you do with a "smart finger" Dont answer that!!! As always, super informative. Ive been looking for a good saw sharpener for a very long time. Think Ive found the one. Cheers!!
Awesome video. Great information. I also enjoy the high production value of your videos. I can tell you have a good team.
I just commented something along the same lines ahhaha
This was SO SICK to watch! Keep crushing it with these awesome videos, Jonathan!! 🔥🔥
Great video. And yes, 0.001mm is one micron! Greetings from the metric world!
Cool video man, now let me see that magic bit making machine!!
The more you know... Cheers for the vid
Oh hey! I'm only 20 minutes north of Santa Maria!
Now find us an East Coast shop to resharpen at :)
Kind of amazing that they did all of that so fast.
For my next sharpening, I plan to use Accurate Cutting Tech in Indianapolis. I have read good things about their work. They are not east coast, but they are close to me.
You my boy blue!
I think I get about as close as these guys when I sharpen freehand with a dremel ;) haha, nice video my cat
Great video. But the Freud industrial blades are awesome. I have CMT and Freud blades. I love my CMT ripping blade. But the Freud premier fusion next gen general purpose blade is hands down the best table saw blade I’ve ever used. Idk why he was saying they aren’t good.
I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.
Joint of the week if you feel like doing those again, secret mitered dovetail.
I'm going all-in on 3 CMT blades finally! I'm wondering why you chose the 24t Rip over the glue joint 30t Rip blade? Seems like anyone who's used a glue joint blade wont give them up for anything else!
There is a local guy that sharpens around me here. It cost me $8 to have a 24 tooth blade sharpened. and $4 to get my 2 3/8" Forstner bit sharpened. Gives you an idea of his price range.
Hey, is this where I learn about blade sharpening?
Looking at the blades you use, is a flat bottomed grind of some kind (tcg, ftg) not needed in a cross cut blade? Or do you just use your rip for that when that's needed?
Also, I got up early to wait for this video and still missed it. Lol
Good morning 🌞
I have a forrest blade that has a broken tooth from saw stops brakes. Does anyone know if that would be worth fixing or even possible to fix?
I always just assumed it was like the opening credits of Twin Peaks. Turns out it is way less dramatic and creepy.
Wow, when was the last time any of us saw a CRT?
That blade inspection rig has been around for decades.
I was waiting for someone to notice that. I have been meaning to try to replace it, but the connections from the line generator are very specific and newer monitors will not work. These inspection machines have not been made in a number of years. They were made by a company called California Cedar Products. I found a patent dated 2002 for the machine, so maybe not quite as old as you might think. One of these days when the CRT monitor dies I will be forced to figure it out. Until then I will just have to live with it.
@@mikesteinfelt7315 Well, blade inspection is the first step to a great sharpening job!
And your whole operation seems to be efficient and successful.
If and when it finally does die, inspection cameras are a commodity now so you might be surprised at the cost and resolution you can get today.
While I'd like to patronize you I'm in the NYC metro and have been using Forrest since the '70's, so I'm not about to change now....
Thank you for your comment and some insight into the equipment that you use! 👍
Another problem is wobbling of circular saws
those Diablo blade have lots of pro...if you chip a tooth you can go get another blade at 1/4th the cost while the CMT you'll have to send it in and have it fix and sometime that's not as effective....so you'll lhave to go to HD and brade a blade to finish the project
The CMT looks like a great blade but do they offer a thin kerf that's decent? Lots of folks are using contractor or jobsite saws and I believe that thin is the way to go?
They do
Great video @jonathan
I guess with the 5 axis machine they can do complex geometry like bevel+rake+shear angled teeth like those found on some exotic combo blades...
Re Freud - I think there is some miscommunication here - the Freud diablo stuff I see sold in the USA is not their top of the line industrial blades... So I don't think the comparison is fair. Top notch industrial Freud blades in Europe cost much more than the diablo stuff.
Re nanometer accuracy....I think you went a little overboard there. 1 Nm is a bit less than 10 atoms of iron/cobalt/magnesium etc.... No spinning industrial Cutting machine can be that accurate
3 decimals of a millimeter is exactly microns. 0.001 mm = 1 micron .
Been doing this for 20 yrs. I use Cx100chp give a good quality sharpening.
Question after watching this, which is cheaper getting a blade sharpened or just buy a new one? I guess if you spend couple of hundred on blade but most of us probably spend 50 or so on a blade, just asking.
So...as an East Coast guy (am in Atlanta)...do you have anyone you can recommend on this side of the country?
You are in a major metro area and if I remember correctly there is a decent lumber industry in Georgia. You might try calling a lumber mill there and asking, it’s worth a shot anyway.
Re: CMT saw blades. All of their rip blades seem to be of the type that is not recommended for use with Sawstop. Which rip blade to you recommend?
Watch my sawstop video. I don't worry about it personally. That thing is so fast it would stop a tile blade before it cut you (for legal purposes that my opinion and you should make your own informed decision)
@@katzmosestools Thanks! I'm new to Sawstop, and everyone seems so adamant that you shouldn't use blades with that type of tooth structure. I have seen your Sawstop video - hope SS helped with the cost of brakes & blades! Is there a specific CMT rip blade you recommend? Keep up the good work!
The cmt doesn't have any 8.25 inch saw blades?
I don't know
Does CMT ship to Canada? :D
Ugh, why does the CMT ripping blades have the kickback shoulders...and why Jonathan are you recommending that blade when you have a SS? They explicitly state not to use those types of blades.
Can anyone recommend a good sharpening shop in the Northeast of the US?
Forrest Blades in Clifton, NJ
They not only sell _great_ blades, they sharpen and retooth other brands.
~$35 for a 100 tooth 12" blade + shippin
I think i might use this company. Looks like they actually inspect the blades and make sure they are worth sharpening. Some of these companies advertise on their website like they do all types of inspections and diagnostic… but when you call them, they admit they do anything but sharpen what you send in
They were incredible and their turn around time is like 5x faster than anyone I've used before.
Did I miss the cost to sharpen the blades? Don't remember hearing it in the video? Would be nice to know.
Cost of sharpening depends primarily on the number of teeth. A range similar to the blades we sharpened for JKM is approximately $14.00-$26.00 Please call us at 805-614-9111 if you would like to discuss.
Also my most recent (previous) video breaks it down in detail.
👍👍
Cost?
Stupid question, how do you get the wax off the blades when you get them home?
Just peals off
@@katzmosestools that's correct and pulling with the direction of the teeth.
It blows my mind how they can Sharpen a blade for $20 and have to use all that expensive machinery to do it, that is why most of the sharpeners have gone out of business
Speaking from experience, what drove saw sharpeners out of business was the drastic reduction in price of blades off all types. My dad sharpened saws for most of my life growing up, and it just became cheaper to buy a new carbide blade than have him sharpen, or even replace the teeth. Specialty tools used in commercial settings were often sharpened in their own shops. Almost every customer was either a construction firm, or a construction worker. Even hand saws, which he had machines to re-tooth, sharpen, and set, couldn't be sharpened anymore because of induction hardening. He eventually realized that it was costing him.more money to keep the business going, and sold all but one of his bench grinders.
@@Myopicvisions yeah thats too bad, I know I have always had my stuff sharpened, I always by the best blades, It makes no sense to get a cheap blade it does me no good and gives me poor results. But the last local sharpening company shut down about 2 years ago, now I have a place that I drop them off and the guy takes them somewhere and theyre sharpened its better than the cost of shipping them all over
My guess is because this specific sharpening business is a value-added business to their selling of equipment. If this was not the case, with only two people working there, the investment will just not pay for itself.
But to pay $20 per blade is an absolute bargain.
Probably makes the real money selling Festool.
@Maciej Jan Długosz that’s why most buy the cheap blades from harbor freight.
Can't believe they replace teeth , the cost not worth it . I worked in a tool and cutter shop we did carbide saws allso for awhile . The blades became to cheap to do anything but sharpen. And eventually stopped doing them at all no one wanted to pay
So what you're saying is that this is *slightly* better than the Harbor Freight DIY model? 😂 Thanks for the lead on a sharpening service, it's one less thing I need to google. I also purchased my first CMT blade and absolutely love it! Also, as an avid ToT viewer, the machinist jargon used to trip me up. I found this to be very informative: www.southadams.k12.in.us/Page/453
sorry to get off topic here. but you have covered many kinds of joints for wood working. I have yet to see the correct joint for a three way joint. I'm trying to build a frame box with wire on the side to put my garbage in. (damn varmints) anyway. The one i built is just a few year old and the top board keeps coming off on the front I assume this is from bags hitting it when they go in and out.If you need a picture I can get you one if are not understanding what i'm asking. Basicly like you did in this video here czcams.com/video/rRZBUbMjxWY/video.html but i'll be useing 2x4 not square what would you suggest?
Wow! Why not just charge for the blade on every job. Collect bad blades, get them sharpened and charge for them. I charge for blades on every job. Recip blades if I use a sawzall, circular saw blades when I use them in their job, oscillating blades, drill bits... everything. This is how I can ensure I have them in every job!
Because that's not feasible in our profession (furniture making). If you're doing it right you're using multiple blades per project and maybe making just a few cuts. This isn't construction or handyman work we're talking about. The right blades makes a difference in the amount of labor you do so therfore maintaining high quality blades actually saves money. PLUS! If you watch my previous video I break down how much more expensive cheap blades. They're a lot less cost effective than high quality blades.
Clicked on the video bc we have the same last name
First comment?!
I am disappointed I didn’t get a “gentlemen” after wishing for a smart finger.
Why take 10 thousandths off the top (outside)? Why take anything off the top? It's not necessary.
41st.
Here I was thinking last week "How can sharpening blades be so cheap if you're paying your workers a living wage? That's got to take so long to do."
Here I am this week: "Oh, duh, of course they use computers now."
My wife wishes I had a smart finger
Every time I see your videos I can't help but think how much you look like Jimmy Kimmel. I mean same cut, same face, and even same accent. Are you related to him by any chance?
Will they sharpen "mid-tier" blades or only elitist blades?
They retoothed and sharpened his red Freud blade didn't they?
@Maciej Jan Długosz I think of $50-100 as mid-tier compared to Ridge Carbide, Forrest, Systematic or FS.
Freud is in this middle tier, above their Diablo line and below the "premium" blades mentioned
why not just get a new blade?
Well I can understand that train of thought as here in Md I have yet to see any sharpening service do a top notch job. They take off too much material and they all seem to think it's necessary to sharpen the teeth on the outside not just the face. It wears down a blade faster so they can sell you another one you see. A scam in my book.
That's what your wife said
Don’t try this at home. Lol
That retipping is sloppy. I retipe u wouldnt tell the difference. Im pretty good at what i do. Jus bragging
Where are your masks, people?
LMFAO. 😂
