Dull Hole Saws?

[@dollyhadbraces9361]

Respect from an obsessed 30 year plumber, all these points are on hit!

[@ramonartful]

Ok cool! You guys would know! Much thanks.

[@DaileyWoodworks]

Keep sharing these tricks! I’m pretty much self taught. So those “obvious things” from you decades of experience are completely new to some of us. Thanks, I always learn something from your videos

[@rickdafler2515]

I love it. I come to learn one thing and pick up four or five new ideas. THANKS, Ramon!

[@ramonartful]

I dig hearing that. Much thanks

[@lenturnbow8038]

As everyone else says, thank you for these great tips! I found it far easier to clamp the pilotless arbor in my angled bench vise. As I unscrewed the hole saw and braced it with my left hand, I used a Mototool cutoff blade to touch up each tooth top. It was really fast and easy to do; left the teeth scary sharp.

[@ramonartful]

It’s amazing how well they cut with a touch up! Thanks for the input and feedback.

Thanks Ramon, I was ready to go by a new 4” hole dozer and when I found your video I tried your technique with my grinder, it worked well and now I just saved $40

[@ramonartful]

Good tips! Wafer wheels can fly apart pretty easy, might want to keep a guard on that grinder with wafers!

Yeah…that’s a good point! Here I’m not taxing the wheel at all…probably not much chance of that. But you can never be too safe! Much thanks.

@@ramonartful I have a curved model that is challenging to restore accurately do you use them?

[@billf9526]

Great tips, thanks! Chugging through a 4x6 with an old hole saw bit… the wood being a tad wet doesn’t help (treated). I had broken out the files but decided to search and found this. Thanks!! 👍

[@ramonartful]

Oh yeah…wet PT is a bear😆. Another thing I’ve done that’s not in the video is grind most of the teeth away. Leave four or so…however many works with the teeth that are there. Try to make em bigger when you grind. This will cut way faster with less clogging. Anyway, have fun. Much thanks.

[@redridgemillwork4188]

Just subbed baby... Coz I just wanna hear the chuckle after you describe a little nugget! U da man Ramon

[@ramonartful]

Thanks! Ha ha 😬👊🏼

[@henrysscrollsawworks6917]

Can you use the diablo hole saw without the centering bit

[@ramonartful]

I’m not sure about the Diablo. However, I do that often by simply cutting a hole in scrap 1/4”…then use that as a template or guide to drill holes without a centering bit. Just clamp the template down , yeah? Works well.

[@charlesgray1981]

Another great video. I can’t wait to try your sharpening technique. I would want to know if you have tried a Dremel with a cutting wheel. I know it would be slower but for us less talented folks it might be safer. LOL

[@ramonartful]

Hello Charles. I have not used a Dremel for this...I’m sure it would work as well. The guard gets in the way a bit with these types of grinders but may be a good alternative. Much thanks 🙏🏼

[@OldSneelock]

I used a Dremel with a pink grindstone. I could shape the stone to a rounded edge. That let me shape the gullet while I sharpened the tooth. Running the smaller wheel and slowing down the Dremel to about 10,000 rpm keeps it from bluing the tooth. Sharpening can be a run what ya brung process. The angle grinder does a decent job.

[@Rusty6450]

Great tips on how to sharpen my existing tools. I am a novice and did notice a 'wobble' on the hole saw on the drill press. Should that be a concern? Thanks.

[@ramonartful]

You’re right…hole saws do tend to wobble a bit. Generally, lower speeds should be used. This makes the cuts safer by helping to maintain control as the cutter contacts the material. Also, lower speeds will keep the small tips of the teeth from overheating, which can quickly dull the tool. And the wobble of the hole saw will smooth out as the cutter engages the wood. Thanks

[@karyldavidkidd7111]

I have time to save my gear and create less annoyances. Increasing my chances of accomplishment in the first run at it is worth the f'n time. Oooohh, expletive. Thanks bud!

[@ramonartful]

Wait …huh?

[@t.e.1189]

Hey Ramon, I've heard you say a couple of times now that you use to be a production manager work in a commercial shop. Do you have a video explaining your background and history in woodworking? If not it would be great to hear your story. You have lots to share to the woodworking community.

[@ramonartful]

I’ve added this to my requests for KZbin videos. I’ll try to keep it short and not too boring! Thanks a lot for the suggestion!

[@d.k.1394]

Respect

[@ramonartful]

Thank you! I appreciate the view.

[@xman4328]

In case you happen to read and reply,,, What did you do to ensure all the teeth remained the exact same height?? Did you grind the cutting edge of the teeth and not show it?

[@ramonartful]

I grind the leading edge of all the teeth and attempt to use the same pressure and time in the “gullet”. This keeps the teeth the same height. The sharpened teeth cut crisp and clean…It’s amazing how well they cut…way better than new! Hope that makes sense. Thanks

[@zohranbloedjes9770]

As i said definitily worth the effort

[@ramonartful]

Thanks buddy

[@samponette3306]

Is it faster then with a handfile? Or are the teeth too hard for the files?

[@ramonartful]

Years ago I use to use a file. They need to be triangular. But man...it’s a lot of work! When “cut off” disks became popular for small grinders, I thought that the thin shape would work well for this...and they do. Give it a try...they cut so good! Thanks

[@FHG1st]

It works better if you can "clamp the grinder down" and bring the metal up to the grinder disk. Gives you much more control and is easier to manipulate for precision sharpening

[@ramonartful]

That actually makes sense. Someone needs to make a “grinder Dock” 😬 Similar to the Dock that I sell for the Festool Domino. Thanks for your input.

[@instantchow]

Come for the hole saw sharpening, got three more tips!

[@ramonartful]

Ha ha…noice. Thanks for watching !

[@benborsa8266]

Solid tips as usual! 👊🏼 The "table" you built for your bench grinder, what angle do yoy have that set to from the wheel and why? As well as why so low on the wheel? I've always seen and have used jigs and such on the top side of the wheel.

[@ramonartful]

Good question. I had to go see my set up in the shop.😆 The drill bit contacts the wheel dead center...but it appears low in the video due to the camera angle. In other words...if you draw an imaginary line through the drill bit...it would line up with the center of the wheel. The actual angle is matching the end of the drill bit. Those bits are most likely 118° maybe 135°...standard drill bit angles. So I am merely matching that (complimentary angle). Hope that helps

[@benborsa8266]

@@ramonartful haha thats funny. Right on, so that is exclusively for doing drill bits then?

[@ramonartful]

@@benborsa8266 Another good question! This grinder is actually set up for sharpening my Stew Mac scraper...nearly exclusively. It just happened to be the same angle that I needed for the drill bit. But most of my grinding is done on a Tormek. thanks man

[@benborsa8266]

@@ramonartful solud thank you, good sir 👊🏼

[@network_king]

Was curious how to do this till saw no guard on the grinder and fingers an inch away, can't bring myself to finish watching this.

[@ramonartful]

Well, watch the video and take from it what you want. Keep your fingers away, keep your guard on. 🤷🏼‍♂️ It’s an effective solution 😬

[@williamhicks2763]

Great tip on cutting the extra hole before hole sawing. I was helping a friend cut holes in pressure treated plywood over the weekend and wish I had know about that then. The in-line blowers are something I need but the reviews on Amazon are pretty bad. It seems like perhaps they stopped making them in the USA and are now selling cheaper made blowers that do not work as well. One comment I saw said to look around and you could find a rebuildable in-line blower that is made in the USA and much better quality, but for the life of me I can’t find anything that’s not made in China and/or has good reviews. Can anyone point me to a really well made in-line blower? Or perhaps these are still good and a few unlucky customers are dominating the comments. Help please?

[@ramonartful]

Thanks for checking out the video! I used to use the cheaper ones…and they end up failing after a while. The button will develop a leak or sometimes the housing begins to leak. Dynabrade sells a good one. And I see they’ve gone up in price. I had been getting them for around $24. But at least, they’re well made. I believe they’re still made here in the US. www.wurthmachinery.com/DynaJet-In-Line-Blow-Gun-Dynabrade-94467.html?gclid=CjwKCAjw8sCRBhA6EiwA6_IF4f8SsdCOERPuUDEMxmok4DpxWUhKk-0te_s62jwg1ShBDVgCIIvX3RoCVD0QAvD_BwE

[@EFD620G]

One more thing.... most drill presses have speed change capability that never gets used. Try using it,you;ll burn fewer bits.

[@ramonartful]

I change my speeds on the drill press constantly. You’re right, it makes a huge difference. Thanks

[@carterscustomrods]

Have you ever made a wave style hole saw (like the saw system used on Forstner bits from Fisch and Freud)?

[@ramonartful]

I have not. But I have reduced the number of teeth on hole saws by tons of grinding. They cut superbly well without clogging! Thanks

[@josephbree742]

Just found you via Blacktail Studio kzbin.info/door/6I0KzAD7uFTL1qzxyunkvA And he is right, you do have A LOT of great tips. I love the one where you curl up a piece of sandpaper and put it in the drill. Wish I had known about that 2 weeks ago when I was trying to smooth out small holes when I was at work without a file. Very helpful videos, Thanks for putting them out.

Don't leave the battery attached to the tools it will drain it and it can case the battery to fail.

[@ramonartful]

Just now seeing this. But, what you’re saying doesn’t make sense. The tool has a switch…connected to a relay. There’s only a connection to the battery when the trigger is pulled. I’ve never had an issue. 🤷🏼‍♂️ thanks
