Ask This Old House general contractor Tom Silva explains the basics of using a hole saw.

Tools:
Drill driver [amzn.to/2UGSyOk]
Hole saw [amzn.to/2uqU64p]
Steps:
1. Hole saws are typically installed on arbors or mandrels that attach to a drill driver to cut a clean hole in a material.
2. To mount a hole saw to a mandrel:
a. Insert the bit through the center hole.
b. Screw the mounting plate as tight as it goes.
c. Loosen up the mounting plate until the nubs on the plate line up with the holes in the hole saw.
d. Push the mounting plate up and into the holes.
e. Tighten the nut behind the mounting plate until the mandrel is secured to the hole saw.
3. Hole saws come in a variety of diameters and tooth sizes, so choose the right one for the right job.
4. Hole saws often get jammed up with wood pulp and other materials in between their teeth, so every now and then, pull the saw out and clean out between the teeth. The hole saw is likely to be hot, so be careful when doing this.
5. To cut with a hole saw, Tom recommends drilling at a lower speed to ensure the hole saw cuts in the correct spot and doesn’t wander. When the drill bit reaches through the other side of the material but the hole saw itself has not cut through yet, flip the material upside down, line up the drill bit with the hole, and finish the cut from the other side. This will prevent the material from blowing out.
6. Tom emphasizes that the drill and the hole saw should do the work and minimal speed or force should be applied by the user during the cut.

Tom demonstrated a variety of hole saws that can all be found at home centers.

Safety tip. Put a side handle on your drill to gain more control over the hole saw while drilling. These are especially prone to catching in a hole and causing the drill to bind which could cause broken wrists, etc.

When i expect a chance of a drill binding up, i put both my legs next to the drill and hold it with two hands at the same time. Last month i had a 1600 watt drill getting stuck in a concrete floor. This tactic saved me. And also that the drill had a clutch apparently. But just hands would have hurt badly. Put as much body mass on the drill as possible.

yeah I have an old bookcase that I've converted into holding my TV on top but I want to put a few electronics on the shelves below (Apple TV, headphone amp) but it's solid wood in the back, no way to run cables out the back. So I want to drill out a hole in the back of the cabinet to run the power/hdmi/audio cables, etc. I've ordered a hole saw like this for my drill but wasn't sure exactly the technique to use it (I've never used one before) :-)
Tom MF DaSilva! You and Norm are two of my all-time hero’s. I’ve been a carpenter for 20 years and still pick up tricks and tips from your videos. I DO wish you would do a more master class style series from time to time. Nevertheless the PBS format is still priceless.
amazing vídeo! so simple and yet so good! greetings from extreme north of Brazil!
Thank you, sir. It is my first every hole saw lesson.
Thank you for this very well explained hole saw instruction. Thank you 🙏
We used a forstner bit to drill through blocking in my attic when rewiring. When my dad hit a screw with it, it ruined it. To finish up, I grabbed the only other thing I had handy, a step bit from Harbor Freight. I cannot believe how easily that went through, or how nice of a hole it left. So I will definitely remember that for the future. The only real problem is the reach. I was able to go from both sides, so no problem.
I hope no one missed the tip about whole saws being very hot after the us! .I learned that the hard way after reaching for it to clean out the cut out piece stuck in it! Also as he said it is easy to envision a whole saw being a saw that was bent in a circle.
I should have watched this first before using my hole saw for the first time. Great to know I should flip the wood for smooth (both) sides. 👍🏼
I did not know to partially drill one side then flip the board and go at it from the other side. That does make it much easier. Thank you for this information.
Thanks for the learning, I have always just pushed through to the other side. I dont do much woodworking or handyman stuff but if I've done it right it's because of This Old House

Good information thank you
thank you!
if you are using a hole saw on thin metal (like metal studs or an electrical box) make sure you have your drill in clutch mode until the hole saw teeth have started to cut its circular groove into the material. If you don't you run a high risk of bending your pilot bit when the pilot bit breaks through the material and the hole saw makes contact with the material. It took me a few pilot bits to learn this lol

Hole saw. You are the expert.
I have had a set of hole saws for years. I needed a series of 29mm holes, 50 of them, in 40mm MDF. Tried a spade bit and it was hopeless, even after sharpening, used several and none were any good and were very slow. Use the hole saw and it was no better, clogging up and in need of constant cleaning. Bought a better hole saw, similar to the ones shown here and while it was better and eventually got the job done it was also constantly clogging with swarf. Also tried a set of Forstner bits which were no better. Bought an auger bit for some smaller (12mm) holes that was better but still slow and repeated clogging and cleaning.
Thanks for the video =)
Diablo Hole saws and Milwaukee drill is the best combo imo

Thank you for this video, I bought a whole saw set and there were no instructions so this was extremely helpful.

Drill four small holes are the circle to give the cuttings somewhere to go when drilling large holes.
If you need the hole you are creating to be perpendicular to the surface of the timber either use a drill press or a scrap square piece of wood as a guide to create a perfectly vertical pilot hole. Then use that pilot hole to guide your hole saw.
Ive used just about every brand holesaw and Starret carbide tipped are the only hole saws I'll use drilling through timber framing.

@@UzsDc1UZ plastic is so soft compared to wood or metal. The whole saw metal teeth dig into the plastic so fast and deep the whole saw gets stuck almost immediately. By cutting in reverse, the metal creates far smaller cuts, essentially melting the plastic without getting caught. Allowing a far smoother cut in reverse.

Search on Hole Saw Guide Plate, you should find a device that won't help you ;-). But.. you now see what could be easily shop-made out of scraps of plywood. Start with two pcs 6" by 18". Lay them side-by-side. Mark a 6" square in the middle, as a diamond. Cut out those two triangles. Put the plates side-by-side again. Place the 6" hole saw, minus pilot drill, within that square, and shift the plates to snug up on the hole saw. At this point, you could screw or clamp the plates onto your workpiece, and use the hole saw... But I usually get a couple of plywood scraps and a handful of screws to lock the two plates into alignment. Good luck!
