Drilling perfectly centred holes using a Drill Press?

- In this video I'll show you how you can avoid having to buy a lathe for more than 27 years straight. Although I would not recommend that.
The trick is to use your drill press basically like a metal lathe, by chucking up your workpiece in the drill chuck and using the drill press vise like a lathe's tailstock.

Great tip . Let another grandfather share a slightly different method . Put the drill for the hole size in the vise , chuck a smaller drill in the press , lower the chuck , or raise the table, move the vise until the two drill points meet and you are centered . Takes a little longer , but no stress on the drill in the vise . Thanks for this tip from a 75 year old grandpa .
This is a brilliant method! Thanks.
Your grandfather showed you a great trick. You can upgrade it by using the drill chuck to perfectly align the drill bit in the clamp before securing it in place. Love your videos.... you are one very smart guy
Simple, effective and annoyingly obvious after hearing this gem. Thanks Cosmas... This is very useful!
Absolutely brilliant ! I served an engineering apprenticeship and no-one ever taught us that trick: probably because a lathe would have been available some where. I'm almost 3 times older than you and I STILL don't have a lathe ... ;-(
As long as you need a through hole, for a small part like that I’ve always done it in the opposite direction... chuck the part in the drill, lower it to the vise, lock the head of the bolt (in this case) in the vise and lock down the vice to the drill press table. Release the chuck, mount the smaller drill bit and drill through. Flip the part, re-center it with the small drill in the chuck (insuring a parallel hole to the length of the bolt), mount the larger drill bit and drill to the depth required. With my 70-year-old eyes and hands it’s the only way I can insure a straight hole! If you don’t need the through hole then ignore this idea. Like your videos. Please keep them coming!

Amazing! I was saying all kinds of terrible negative things during thee video.
"This is BS!" (at minimum) I still can't imagine how this works so perfectly
Great tip. Thank you. 😁✌🖖
Useful tecnique! Thanks for sharing! Limitation is as long as we can get the work-piece in the chuck as most of these are around 13mm max.
I don't understand. The very first center hole that you drilled you didn't get it in the exact center of the work piece. So then how is the hole going to end up being in the exact center of the workpiece?
My thoughts are that any error in the centering will result in a larger hole than the diameter of the drill bit itself?🤔
Also found this method useless for my problem: What do you do if the item to be drilled is too large to fit in the chuck?
This might work great for a piece 1/2"/12mm or smaller, but I need to drill a perfectly centered hole in a piece about 3" in diameter. Now what? Thales Theorem drawing lines with a T-square???🙄
Clever man, your grandfather!
Wow, very interesting! Thanks for passing on your grandfather's wisdom. My grandfather taught me his method for eating peas. He would say, "I eat my peas with honey, I've done it all my life. It makes my peas taste funny, but it keeps 'em on my knife." :)
50 thumbs up from beginner manual lathe / drill press operator on limited budget!! Bauer you are a true artist! Your Grand-Dad would be so proud of you.
Very impressive !! I gave this a shot and am amazed at how well it works with very minimal set up.Thank you for sharing!
Wow…. I would have never guessed. When you put the bolt in the chuck, I had the ah ha moment. Im gonna try it today!!!! Thank you!!!
If its not perfectly centered? How does it find center when you make that first pilot hole? What am I missing?
This helped me so much, literally the exact kind of part I'm making as an adapter. Thanks for the video!
I just felt my life change, thanks Cosmas.
Very clever. I am shre your Grandfather was proud of you. I love your videos! Keep them coming.
Very clever. Kudos for remembering your grandfather’s tips and teachings!
Neat trick Cosmas! Thank you for sharing it with us.👌👍😎JP
Never doubt your Opa!
Now that's thinking outside the box. Great tip.
Brilliant....I’m going to try it now.
0:44 “still don’t own a lathe at almost 27 years old” 😂. Me neither, and I get by without one, just make do with a pillar drill and a good engineers vice.
5 thumbs down from lathe salespeople
12 now but 1 more up from me.
😂😂😂😂😂
Cool! I had to drill a hole in an ABS end cap, and as it turns out, it's a slip-fit over my drill press chuck, so, with your trick, I got a perfectly centered hole. Thanks for the handy tip. I love UA-cam!
Cosmas, I am a little older than you and I had not seen this done before. Thanks for sharing!!!
Awesome Cosmas! Thank you for sharing.
Very useful to know. Greetings from California. Enjoy your videos.
That was awesome, never ever would I have thought of that.
Thanks for sharing your GP's knowledge. You best be doing something about that lathe issue :)
Cheers
My German friend,you have made my life so much easier, thank you for this ,you've no idea how frustrated I was wondering why the fuck I couldn't get a centered hole but now I don't even have to look,god bless you brother n Much love n respect from Dublin, Ireland 👍
I never tire of these simple solutions that ebb and flow through our consciousness. Thanks for reminding us of this one.
Question: what brand is your drill press chuck? I need a new one and would like to find a the best one possible. Yours seems to have hand and mechanical tightening, which would be . great for mine as well.
Thank you!
Wonderful technique. Thanks for sharing!
This is a very light vice. I need one like this.
Very interesting project. Thanks for sharing. Now you can make threads in the hole and put a threaded rod in it, or a another metric screw/bold.
Thank you. Just found a solution to a problem I was having with a spray gun tip...
The exact solution to a task I'm working on. Thanks
this is a very good way to make a perfect center hole with minimal tools
Excellent! Now I just have to get a more accurate drill press. The Ryobi I have has a one-piece shank and arbor. It is inaccurately made, and cannot be changed or altered easily. Ugh…
Thank you, for your grandfather's solution to my problem!
Few questions I hope you or someone here can answer.
1. Will this work on any length material, like 30cm long?
2. Does the material have to be PERFECTLY straight. I have a metal rod, i mean its straight, but not PERFECTLY straight.
3. Does the drill bit at the bottom have to be PERFECTLY perpendicular in the vice?
1. You have a drill bit 30cm long? Or at least one 15cm and go from both ends hoping to meet in the middle? I know, dad always said don't answer a question with a question. This was two questions...
2. How do you expect to get a hole straight through a workpiece that is not "PERFECTLY" STRAIGHT? A rubber drill bit? Two more questions.
3. Yes. And that's "vise". Drinking is a "vice". So is smoking, gambling and running around. A PERFECTLY straight answer.
Great video and good usable information delivered quickly. Thumbs up.
Everydays a learning day, I appreciate this
Nice video.. But the drill bit has to be perfect virticall right?
Very well done.
Man, am I happy to see this video! Thanks Cosmas.
Excellent , Thank you.
Totally worthwhile video, thank you!
lol, Like it. Will remember this - so obviously simple that it's over looked. Top marks.
Could someone explain again why it doesn't matter whether the drill is exactly in the center? I didn't understand the reason why the hole will be in the middle anyways.
Great tip. Thanks to you and your grandfather!
Yes, that is a good idea to switch position of drill and part for drilling (screw) to avoid bending of drill. But what I still see like problem is to find centre of screw. You made it well. But in fact it was coincidence or your finesse , I would say... Am I right?
Great trick thank you
Thanks for the information. Seems like a very hassle free method.
Why has it taken YT 2 years of delay to provide further proof of the power of inherited DNA and the deep end of the gene pool? Always enjoyed watching the cleverness of you, Cosmas and now also your GP.
Better use this social media fortune that you’ve earned to get a decent Bridgeport (or modern equivalent)……!
Thanks again!
And greetings from the south western corner of Australia.
a very useful genius tip... fantastic
That drill chuck looks awesome, did it came with drill or is it an upgrade? Looks like an Albrecht
Ok but now how do I center the drill press over a work piece that won't fit in the chuck?
So simple and yet just Genious!
Great, I'm having to do this tomorrow.
Wow. I've tried this three times and I still can't get my through-hole to center. Seems very centered at the starting point but wanders off-center by the time the drill has made its way through the piece. I even took the step of chucking the drill in the press (backwards) before I locked it in the vice. What am I doing wrong? Does the vice need to be free-floating?
Grandpa rules, thanks for listening to him
That's a pretty cool trick.
How is this "perfectly" centered if you're eyeballing it? Honest question. Am I missing something here?

Thank you for sharing.
What assures you that the drill bit is perfectly placed vertically to the vise ? sorry but it's not that simple.
It's almost useless if you're drilling longer holes.
A drill block/guide will do the trick.
Nice usefull trick, thank you
Thanks for showing how and sharing that, well done!
I don’t even do any metal work or engineering, but even I thought that was very clever.
I’m almost 30 and still no lathe😞
Just got an 8” jointer though 😁
Alex Van Nostrand I’m nearly 59 and haven’t got either a lathe or a jointer.
@@markharris5771 I'm already 59 and neither lathe nor jointer
I'm 68 and I'm building mine. 😸
OK, I learned something. You got me there. But what is this hex bolt with a through-hole in it useful for I wonder?
Could use for many things but that's now really the point. It's showing how to do something that otherwise can be difficult, cost more money and even know simple, can cause a lot of inconsistency and problems if your trying to center and drill out or really a cool ass trick. The point was never a screw/bolt, that just a demo and this method can help in many ways. Which you said you learned something. I know I did. This comment is not meant to dickish in anyway BTW. I'm a super newb at this and landed on some pretty hard times. Definitely helps with some side projects. Stay blessed 👍
How do you ensure the drill bit is perpendicular?
Great video... one suggestion, though... get a lapel mic, your audio is hard to listen to when you are speaking in the shop.
I'm more interested in what this part is for. Hex head on something with no threads is puzzling to say the least.
It was probably just to demonstrate the procedure. Not everything has to have a purpose
Proper clever that is.
Thank you!
Nice job and excellent idea. Don’t worry about any negative comments from some folks. They are wanna-be’ s that can’t probably do anything mechanical.
CLUTCH!
Pretty clever, thanks for sharing
who knew you could drill up
Comas bauer please building and shooting the slingshot crossbow still ball video please!!!
Interesting. But it would seem that the drill bit would need to be accurately plumb to maintain an accurate hole size.
I was thinking the same thing, but I suspect that as the chuck is turning, it will accuratly locate the drill bit (making it plumb), overpowering the vice grip.
Drill bits generally aren't rigid enough to cut a significantly larger diameter hole by misalignment. The shaft will bend, and the part inside the hole will be straight. That's why when you chuck up a drill bit you're supposed to have some of the shaft without flutes exposed because this part isn't hardened and can bend without snapping. You face the exact same situation using a drill press the 'conventional' way. If you need a perfectly accurate finished hole size you use an undersized drill bit and then a reamer to get it to the final dimension.
I have a lathe and still liked it
As always genius!
I whish i knew this trick before i bought a lathe.
Thanks. You make my day.🙂👍👍👍
Very interesting, and very clever.
Fabulous. Thanks for that tip.
Awesome tip. Thank you! :)
It would be a very interesting video if you actually showed an imperfectly sharpened drill bit actually moving your workpiece (self centering) like you said to illustrate that this would actually happen. Love your videos Cosmas! Keep them coming!
very cool trick.
Nice one
Very clever thanks
Oooooo that's clever !!
Thank you (and thank your Grandfather).
Excelente
Neat!
Sorry but I don't see how this is suppose to work.
If the initial pilot hole is off center when it's all clamped up - it won't be in the exact center. So eyeballing the initial pilot hole, clamping everything, doesn't ensure exact center. It might be close but it will be off center. If you're an 1/8th inch off center for the first hole, you're an 1/8th inch off for the entire piece and the bit will warble once raised. or it will be pulled to center not drilling a straight hole but rather one at an angle towards center...
It seems that way to me anyway.
Because the workpiece is spinning the pilot hole will be exactly concentric with the axies of rotation even if the cutting tool is not on that axies.
@@CosmasBauer - Thanx for the response Cosmas -and I do understand that part of it... or the theory of it. But I keep seeing it like a lathe I guess. or not starting the cut dead center if the bit isn't perfectly in center. Ican see it going towards center at an angle, then possibly straightening out but... lol I don't know. I'm just going to have to try in short. lol
If I mount a piece on a lathe. Spin the piece and stick a gouge or other cutting tool even close to center, it cuts a circle however far off center I am with the tool. If I'm off center with a bit, it will warble the bit as it cuts and either break the bit or tear up the work piece. And there in lays my not visualizing this - even seeing it in your video... I keep seeing the initial cut off center or angled towards center as it moves the bit to try and correct itself.
As stated, I'm just going to have to try it out. And be bedazzled if it actually works. lol
Ive used this trick since I was a kid. Dont remember who taught me though.. Its not something I do on a daily basis but its a handy thing to know. Its also quite amusing to see the initial reaction in peoples faces then you make a setup like this "Emh... I thought you knew what you are doing, im just pushing papers and even i know its the other way around dumbfuck" 😂
Who the hell thought this WASN'T a good tip?
Lathe manufacturers.
Yeah, probably. haha.
