Safely & Effortlessly Create LARGE Holes
Вставка
- Опубліковано 4 жов 2024
- SHOP NOTES: This old adjustable hole saw (or a new one like it) can be used with or without a drill press, but when cutting holes this large in wood I always opt for the drill press. There's a couple more things to add, so a follow-up Q&A vid is bound to follow. Be sure to add your two cents in the comments.
I found two similar tools on Amazon. The first one below looks almost identical to mine, but the second one looks promising too and might be the better value:

🛒 Multi Size Hole Cutter with Dust Bowl: amzn.to/3Rr1ZxR

Wow, a hole new topic!
#ISeeWhatYouDidThere
Great video.
Pretty simple concept for a difficult task.
If you wanted a clean cut on the back side, you might want to drill halfway and flip it.
Great tip!
What a great tool! Fifteen minutes ago I didn't know it existed. Now I feel like I can't live without one.
I totally understand that feeling. I remember seeing it for the first time myself many years ago and thinking “Where has this been all my life?”
Nice tool! I often see fly cutters in the DIY shops near me but never with the guard and case. The cost of this kit seems to be about the same as two or three large high-quality single-diameter holesaws, but you get a tool that it is infinitely adjustable. I put it on my Santa list!
A few weeks ago my mother (94) received a new oxygen supply of 10 tall tanks and 5 small ones so using a similar (though without the guard) single tip circle cutter I cut 12 holes in a bottom board (3 - 4 - 5) and 10 holes (3 - 4 - 3) in a top board I made a holding rack. I used the top spaces that weren't cut to set two of the small tanks. I did begin cutting all the way through the top board to score the bottom one where the holes lined up but as the center bit located the the uncut holes I could half cut (using Shopsmith depth gauge) then flip each board over to cut from both sides leaving a much nicer edge and removed disc. It holds 9 of the large tanks (one went in the portable stand) and all 5 of the small ones. Interesting you covering a tool I just used. FYI you can turn the cutter around if you wanted the disc and not the hole.
That’s a great tip and way to go on helping out your mom.
Great video! I have an old fly cutter without any guards. There was an old issue of Wood magazine with a tip that recommended cutting an orange plexiglass cover as a safety guard. I had better plan on doing that sooner than later!
Do it sooner, so it’ll be ready to use when you need it.
Scott, As usual, another great video! I've always been leery when using circle cutters of this type-which lack the outer circular "guard". Great demonstration! Now I might be able to make corn hole platforms on the Shopsmith if there is 9 inches clearance from the way tubes to the spindle which I seem to recall being the problem in the past.
I am confused by your last statement about the quality of bearing and the guard in relation to the squareness of the cut. The squareness of the cut depends on whether the bit is square to the table, and if the cutter is parallel to the drill bit. The bearing in the guard is riding on the spindle of the hole cutter. The guard and the bearing have nothing to do with the actual cut. I agree that good bearing are very important to keep the guard from vibrating excessively which could cause a safety issue, but again the squareness of the cut has nothing to do with the guard or bearings.
Also, I would consult the speed chart to determine the proper speed as it relates to the diameter of the hole. This is where the Power Pro has a great advantage over the conventional headstock if one doesn't have the "crapometer" you used several videos ago.jim
I guess I wasn’t very clear in what I was trying to say. This particular unit, because of the metal frame on the dome, ax like a drill guide. This tool can 100% be used for making corn hole boards, but I would use it with a hand drill, not a drill press, due to the position of the hole in the board. The Shopsmith drill press will max out before you get to the 9 inch position.
That worked better than I expected. I can appreciate that a HSS cutter works better in wood than the carbide. Another big plus for HSS is the ease of sharpening on a grinding wheel.
Dave.
Correct. The carbide cutter is typically used for drilling through sheet metal. It can be used for wood, but it’s nowhere near as clean a cut as the HSS cutter.
I'm not sure how I've gotten this far without knowing what a fly cutter is. Especially since one is in my black tool box fourth drawer down in the left. One of the mant things that was given to be with my 86 510. 9:25 I don't say this lightly, but you have really expedited my smithing and I don't think I would have forced myself through the manual at this speed. You provide a very real service.
I used one years ago, admittedly not one with a guard which in my mind is a much better idea. I do so little of the drilling of big holes that it does not look like a good fit for me, I still have a number of hole saws that still work fairly well. I must admit that they are not as accurate as I would like, the whole tends to wobble even with drill press, the hole I end up is little bigger than what I really like. so I only use it for rough cut stuff. if someone ends up buy one of these, I would not buy one that did not have the guard attachment because it helps to stabilize the drill as you plunge into whatever your drilling. without it you could get a catch that could be dangerous. I agree, buying one that is well made is a must.
Yeah, some things are best not going the cheap route.
Wow. I have never used a tool like the one in your video. Thanks for coming up with a new tool we can use with our ShopSmith.
“New” is subjective, but I know what you mean! Happy to share. Scott
@@MyGrowthRings Hahahahaha
My father's adjustable hole saw cutter, 1957-era, was with his Shopsmith parts. And, I do remember using it once with him and it being cool. There is no safety guard or anything, unlike this modern version. Hooking it up, modern day, it triggered off all of my danger zone warnings. It seemed like a better idea to just go buy the exact size I needed.
That’s true, but have you priced a 4 3/16 inch hole saw lately? Thankfully I had some flexibility in the sizing of this hole, but had it been critical, the cost would’ve been exorbitant. I’m quite comfortable with this tool, and clearly, I recommend it. Scott
Neat! Thanks for sharing.
Thanks for watching and commenting!
That is a cool tool.👍👍😀
I have found it quite useful. Sure beats trying to freehand with a jigsaw.
@@MyGrowthRings
I did not know that was available. I’ve drilled various holes along the circumference , then as you mentioned, finished with a jigsaw but never had your results. Again, thanks for the heads up!
@@johnrice4273 It has served me well for many years.
Great video Scott, that is a substantial tool compared to the fly cutters I have seen and used. But I agree with @StephenADraper I feel much safer using a hole saw. And have collected a few large and odd sizes over the years for specific projects.
I also use hole saws. It all depends on if the size is standard and on hand.
@@MyGrowthRings I use a 6 inch hole saw on a DeWalt 235G 1/2 inch drill to cut out the whole for corn hole platforms with considerable difficulty. I wish I could position the platform on the Shopsmith, but the position of the hole being 9 inches from the top won't let me use my Shopsmith in the vertical mode....maybe I can move the headstock all the way to the right and use the horizontal mode, but how do I secure the piece?
Really interesting tool. Thanks for sharing this, Scott. I've got an exhaust fan project coming up and one of these will be great for cutting the holes to the attic. Check out some other options that have an integrated vac port in the bowl. The newer models with dual cutters like the one from Klein Tools might be what I go with.
The dual cutter version can be tricky to get tuned-in, but the balance can be good if you get it just right.
I guess if you want to make wheels this is the tool for you. For drilling perfect large holes, I like spur bits, or large Forstner bits. Just my preference. Great video Scott.
A 4 inch forstner? Did you get that promotion?
@@jerbear7952 Ha! You are exactly right about that.
FIRE ZE LASER! -Frau Farbissina
Interesting product, it does not look like it has enough mass to get a good cut and it looks like you would get bit of deflection with the larger holes, how did you find it?
It has always worked well for me. It does have some counterbalance weights that I didn’t mention, but that come in hand on drilling the larger holes.
Just a word of caution. I've installed acoustic ceilings for 37 years. Over that time I've seen a lot of electricians cut holes in ceiling tiles for can lights with hole saws and fly blades...don't do that. Breathing the mineral fibers is bad juju. Use an old fashioned key hole saw. (Don't use circular saws either)
Good call.
👍

What brand of bibs are you wearing?
I like to think of it as an apron! It’s nice and heavy, so I use it whenever I stand the chance of getting hit by something. Here’s the link: amzn.to/3xlzdI3
Hate to bother you but I bought a 1954 mark v came with multiple Jacobs chucks one has 2 "Morse taper but has bearing in shaft that makes the chuck spin freely is it for pen making I have never done pens thanx very interesting way of cutting holes would work good for Chuck spacers for bowls
Yes, it can be used for that. There are occasions when you might want to shorten the length of a mandrel, so with that the excess length can pass through the tailstock. That can come in handy.
Thankyou
@@lorriebuxton2041 You are welcome.
I have one of these I inherited with my SS. It has no guard but two cutters. I’ve used it only a few times because it’s scary! But the few times I used it, I found it /very/ difficult to adjust the two cutters identically. Now I’m thinking to remove one cutter and use only one at a time. Your thoughts?
I never liked the two cutter versions, but they were made to be balanced with two in place. This one was made to run balanced with one. I wouldn’t remove one, personally.
