- WW'nTips-n-Tricks #092: Square Holes
Holes are a mainstay of woodworking. Square holes for things like mortise and tenon joinery is standard practice. You can cut them with chisels, even the specialty "mortising chisel" and by machine. But in the past years the perfect machine for making square holes has been left by the wayside.
So today I explore the mortising machine/hollow chisel mortiser and offer up lots of little tips along the way.
This video is an excerpt from the Router Table Build series which will be behind a paywall. But this portion of a larger segment on cutting the joinery of the frame in our frame and panel construction is specialized enough I thought it'd make a good tip.
So enjoy and keep your eyes out for our Router Table Build series.

in middle school wood shop, this was the only tool that i didn't understand. eventually learned how to use it in high school on multiple projects. such a useful machine.
Yep, and going out of favor to dominos.
Really interesting video, thanks. I picked up one of those attachments for a drill press at a yard sale and yes, the guy practically gave it to me. It came with a whole set of bits and chisels, but only one of them had been used. It had no instructions, so I had to figure that all out for myself, but when I got it working I was delighted with it. I found I could only drill a little way into the hole before I had to lift the bit and clear the wood, but that's probably because I had no idea that the bit needs to be lower than the chisel. Next time I use it, I will experiment with that. Anyway, it works a charm and I wold never buy a dedicated machine to replace it. It does what I need done, and the number of times I use it makes a dedicated machine just an unnecessary expense.
Thanks again for the education. I think you have improved my drill press attachment quite a bit.
If it serves your needs....
Worked well enough for me in 1957 high school wood shop.
consistent and reliable but not flashy enough for the digital age. not many manufacturers make these anymore.
Very useful for a beginner such as myself. Thank you so much.
Thanks that was both interesting and helpful. 11 or 12 years ago I bought one of the Morticing drill press attachments. It is still sitting in one of the shop cabinets, never been mounted and still has the original packing grease on all the parts. Been thinking of giving it a whirl, although I can see there will be a good amount of strain put on the drill press. Thanks for sharing, it is always nice to watch another effort of Worth the Effort.
Thanks, my attachement had enough strain to bend the handles of the drill press.
Excellent video - thanks! A great, thorough walk-through of using the mortiser. I am definitely looking forward to adding one to my woodworking tools.
"it's a generalized perfect". This describes most of my work.
I'm definitely in the "generalized perfect" crowd too.
This was well presented - thank you
Great demo! Just got a new to machine and this was useful!
I just saw a Facebook ad for one of these with your face in it! I hope that you were paid for that. If so, moving up in the world!
foriegn company ripping off creators. says all you need to know about the company.
10:30 Seems the authorities don't like your opinion and are now out to get you. Thank you for the video!
That was cool. Hadn't ever seen one of those in action before.
They serve a need.
Well done! Learned a lot. Ty!
Dremel for the win
nice wood work
Been using mine a lot lately they are pretty simple but very effective
Blessing when it's needed.
This was very informative .Thanks for sharing the information.
Thanks
great explanation. The only other one that I have seen that was as thorough was the one Charles Neil did many years ago.
Ya, he always has good explinations.
@@wortheffort I agree. I will miss him :(
Great video, thanks for the effort. I'd give 10 thumbs up if I could.
Hollow Chisel is the term.
Great tips did have a Delta one works great 👍
It's a standard design, kinda like bandsaws. From my understanding you can make all work well. 'cept for drill press attachements.
I've got most of a drill press attachment one that I got with my second hand drill press. I should really have a play with it.
Play with it for sure. But keep an eye out for a real hollow chisel mortiser too.
I have a drill,press attachment. I have a sturdy 17 inch drill press. I thought mine worked ok. Biggest drawback was the time installing and removing the attachment. Quicker to use a plunge router.
Ya, swapping back and forth is a pain.
Can I ask you the brand of your drill it’s really nice and it’s great video thank you
Awesome tips. I have a delta and love to use it. Mine does not have those nice shims or the sharpener. I need to find one of those sharpeners.
Thanks, most woodworking stores sell em.
I really really want one of those, but it's about five major tools down on my list.
You'll find em everywhere when not looking or them.
I think the domino makes sense to speed up joinery for the professional but personally I'd like to make more through mortise joinery which I think looks better with square faces. What do you think of these for getting perfect through mortises?
You drill from both sides....
When your mortiser turns on, there is a metal on metal rubbing noise. Mine makes the same noise when turned on. If I push the chisel forward a little, that noise is gone. It turns out, as soon as I tighten down the chisel, the screw pushes it back a tiny bit, but auger bit stays in center. So the bit is scraping the front of chisel. After a few cuts, the chisel and auger bit get really hot. I tried oil to reduce friction between them, but as soon as wood chips are hollowed out, it starts rubbing again. Have you done anything to solve this?
Please help. Thanks.

Bought the attachment for my drill press. Doesn’t work very well.
Hey nice video, very helpful for a new mortisir owner. I also noticed the Dewalt rolling cart which is typically sold for the tablesaw behind you. But you have mounted the planer on it. do you need special modifications to do that?
Not really. Used same mounts.
@@wortheffort thanks for answering. one more thing. Do you actually raise it up and down on that cart? Or do you just leave it on the low level and use it that way? My Dewalt planer just arrived and I'm thinking out how to mount it in my small garage workspace. I will have to move it around for storage and such.
Cool machine, way to pricey for me. Did you do a video on drilling a "Square Mortise hole". I'm sure the expression was wrong, I think you know what I meant.
You can often find them for a few hundred on craigslist.
Can the "square" hole drill bit, be used in a hand held drill, to make a mortise on a frame in situ ... ?
Phil Melson no, you need the leverage.
How would you drill that same square hole with your mortice machine if you needed the cut made on the end edge side and 3" long. How could you fit a 3.5" wide x 10" long 3/4" thick plywood board on that base? Does it swivel away and let you use a lower base? Maybe I'd need to cut out a piece of the steel drill base to slide the board up into and then clamp.
It is a Mortising chisel bit I guess
Ya, I suck with nouns.
Hey can I ask for some quick advice? I have a shorn off bolt that holds a gear to a driven spindle. It is held in such a way that I can only reach it from the bottom of the headstock - essentially a 6in diameter pipe and the bolt is 8in down the "pipe". I do not own welding equipment. How would I either carve a notch into the flush bolt to remove with a screwdriver or remove the bolt another way?
That's one above my pay grade. Not a machinist.
If you had a dremel with the wand attachment you could possibly put the groove in the bolt head with a burr or small cutoff wheel. I would also recommend trying a left handed drill bet. Yes, there is such a thing. You use them with the drill in the reverse direction. If the bolt isn't too tight, they will often catch and spin the bolt out for you.
Hey question, do you know anything about the square hammer driven, mortise chisels? And have you done a video on them? And or would you do one? I'm just wondering the machine is way out of my price range. But I thought that would be a fun way to try making them. Thanks either way.
No but if it’s hammer driven just use a regular mortise chisel or bench chisel.
In advance I know it’s not a mortise but just a square hole. I’ve used the square hole, hammer driven, METAL punches on wood a few (less than a dozen) times on wood. They’re made to go all the way through metal stock starting with a round punch and flaring to a square. It makes a nice square hole say for a square plug. I predrill most of the waste away. Then hammer all the way through when the exit hole was hidden. Or Flipped the punch and beat the square end in a few fraction of inches. Again I know it’s not a mortise, just a square hole. I don’t have the production need or cash for a dedicated mortiser.
I have a table top one
That's what I was using.
You mentioned domino couple times. Are you talking about the festool domino mortising tool? That tool seems incredibly expensive. Are there more economical or reasonable alternatives?
By the way I love your videos
a chisel
Thanks
Where would you go to find a used one? Is there a website you'd recommend?
clubs, classifieds, estate sales, ask other woodworkers.
Where can i buy this square drill bit?
It’s called a mortising bit. Available lotsa places.
What is the name of this tool.?
read the title
That's great but is headache for you why you have to be so much force I watch Asian videos The Machine the one did use a lot easier and faster and doesn't need much force or wait
What is an email I can contact you at?
