- Today we're talking about choosing the right size pre drill bit. Pre drilling is important in woodworking and carpentry, to prevent the risk splitting or cracking your work piece. Therefore, in this video I'll cover two options for choosing the right size pre drill bit, and show you some examples of what happens when you do and don't pre drill.

10 years ago, there would no quick, straightforward way for a layperson like me to get these fundamentals. Cool!
Books and magazines, mate
Now that's what I call succinct! Only the important stuff in a minimum of time without being superficial, clear advice to memorize - thank you!
Wolfgang, you are always so supportive! Thank you.
Honor to whom honor is due! :)
Great, and to the point. Only thing that could have made the better. Would have been a link to the chart for what size drill bit to use. But thanks!
That's the right way for explanation: clear, short and simple!
This was awesome. I’m just hanging up a curtain rod and even the simplest task can seem like rocket science when you’re uninformed or uneducated. Thanks for this.
Some additional feedback:
You chose great viewing angles. I can’t tell you how crucial that is for beginners.
You spoke very clearly.
Your reference material was pretty helpful.
Keep up the good work!
"When in doubt, pre drill"
Best advice yet! Great video. So glad i found your channel! Been very helpful as a beginner DIY-er
I'm so glad you are here! Thanks for watching!
Being in pretty good shape for a 71 year old grandma, I decided to put the last 3 planks of my deck back because waiting around for anyone to do it, I’ll be dead before that. They’re 8’ long, 4” wide and I got them in place. I started putting in the nails because they already had the holes underneath them. They only went halfway in and would not budge. So I took them out and decided to look online to see what was going on. I always look for the shortest videos - long ones bore me. You made it precise, to the point and now I know what I’m going to do. Thank you and may God bless you, Joan 👵🏼🪛🧰
I wish all DIY videos were this clearly presented. Great work and very helpful for my project.
Exactly what I needed! Straight to the point with no fluff and extras - Perfect for this beginner DIYer. THANK YOU!!

Thanks for doing some basics. The cross sections are great teaching tools. I appreciate the effort.
You're very welcome!
Thank for your Professionalism from Thailand.
Simple and straightforward! Thank you!
Your instructions, tone confidence come through, great job. Thank you. You answered all my questions not making me feel stupid.
Great visuals and explanation. I've never owned a drill and had no idea the complexity. Thank you!
Glad it was helpful!
Excellent guide. Informative and it the point!
Thanks so much.
Awesome stuff! Thank you for this video. It was exactly what I needed and more.
Living in Japan and can't speak the language, so can't ask anyone in the hardware store for assistance.
This vid helped me a lot and love the positiv energy!
So simple and helpful, thank you 😊
Concise and to the point. Good video.
Excellent information. Thank you so much. Beautiful presentation. The best most succinct advice for woodworking I've ever seen on UA-cam.
Thank you for the comment!
Finally a video on the subject I enjoyed
Wow! Such a good teacher!!
Thanks man. Hope you are well. Very helpful video
Quick, easy, concise. Perfect how to video. Thanks 🙂
Thanks for watching Jen!
Thank you so much! I had to take the time out and leave a comment, quick, short, and right to the point. Earned yourself a new subscriber!
Hey thanks Molly!
Thanks, I don’t know why I’m barely finding your channel and I’m definitely subscribing to your channel. I’m in a construction class and your videos are helping me understand better. 😊
Thanks for subbing... Yes, I'm currently on the wrong side of UA-cam's algorithms... it's all a game with them. :) Let me know if you have questions.
Awesome video, and great tip on the drill.
A lot of people forget how much torque those little machines can produce. You can easily fuck up a nice project even if you pre-drilled, because you over shoot it by a bit.
Thanks for. Or assuming everyone know this stuff! I’ve learned very valuable info from you. Thank you!
Awesome video. Very helpful!
Thanks for the comment.
Very informative and helpful. I always crack the lumber. Exactly what I needed to know. Many thanks!
Glad this helped you out.
TQ for sharing knowledge. Keep it up.
Brilliant video. Thanks.
A good friend of mine/Old Timer very experienced Carpenter showed me on a job site once, to help a screw go through tuff wood easier, to rub the screw threads on your scalp using your natural oils to lubricate the threads or furniture Polish. He always kept a can of Pledge furniture polish in his truck that he would also use on window and sliding glass door tracks. Watch and listen to the Old Timer's as they work Smarter.
Great comment. Thanks for sharing.
Great video
Thank you
Perfect! Thank you!

Thanks. Super helpful.
right to the point. Great ... I don't like commentary when I'm in the middle of something. Thanks!
Many thanks. That's much useful indeed
Glad it was helpful!
that was so helpful, thank you
very simple very helpful!!!
Glad it was helpful! Thanks for the comment
Excellent video
I watched 3 other videos before this one and you explained things in such a way that a novice understands.
Great to hear, thank you!
Very helpful thank you 🙌🏻
Glad it was helpful!
Thanks for this!
Great video. I find most of the screws i use a 4mm counterbore is best having tested all sizes. As i only had 1 bit rhat size I have now ordered 20!
Unless its just a rough piece I tend to counterbore all screwa for neatness and safety.
great help😀. thank you
If the wood is not especially prone to splitting, then the predrill can be a little smaller than the shank, which allows the screw to fit tighter and hold stronger.
Hello, I like your content and I'm learning how to work with wood materials, thanks to you! One question, I have ST3.5x19 wood screws included to assemble for adjustable desk, what number is this screw? I don't see ST3.5x19 in any of the wood screw chart online. I just want to find out a proper drill bit size for pilot holes. Can you please help me on this?
I just found your channel and am enjoying your tool basics videos, especially the router ones. Could you put together a beginner/newbie playlist to make navigation easier?
I'll work on that Roam Sweet Home. Thanks for the comment!
Very helpful
What's the best 3/16 replacement woodcutting or multipurpose bit for dremel trio?
Thanks very much.
1:09 This been so helpful thank you.
Similar to drilling a slightly larger diameter hole then running a tap but in wood working applications. Short, well focused, couldn't ask for more.
Thanks for these helpful visuals. I'm no stranger to assembling furniture out of a box, but this afternoon I hit a snag when trying to put together a bamboo dresser. I think they didn't drill the pilot holes deep enough to accommodate the screws that came with it, and it was offering a lot of resistance and sounding awful, so I stopped before I split it. I wouldn't have thought that a variety of grass could be harder than oak, but after having a lightbulb moment watching your video, I did some more research. And I will *definitely* be fixing those pilot holes before trying to tackle it again!
Awesome! Thank you for commenting.
Thank you for explaining this like the viewer is five years old without making the viewer (me) feel dumb!!😂😅
Lol, glad you learned something. :) Thank you for taking the time to comment.
Great video!!!
Thank you for subscribing Mike! 👊
Excellent demos. I feel very silly for eyeballing screws instead of looking for a chart.
Your comment on using a screwdriver so you know how much torque is going in made me laugh - I was doing something where I didn’t care about aesthetics recently. I switched from Phillips to Torx screws and was trying the impact driver I recently bought. 3” screw in less than a second. The only difference when I had pilot holes was that the screws went in straighter. Absolutely no tactile feedback on how much force I was using :)
Great! Thanks!. . .
Perfect. No minimum “10 mins” chatter like other videos.
I try to keep it straight to the point. Thanks for noticing and commenting.
Thanks.
Argh went to local hardware store told them what I want to do -- when I saw the threaded screw/nails they suggested, I mentioned that I would struggle to do it and they told me not to worry a screwdriver would be fine 😭😭😭😭 screwdriver is not fine I am just overweight & unfit not strong 🤣🤣 will go get a drill bit tomorrow to make a pilot hole which makes complete sense. Thanks for the video.
Thanks for the comment. Reach out if you need help.
Is it possible to pre drill something then use a countersink bit to drill for counter sink on the poo site side of something ?
Right to the point in 3 minutes and no yada yadaaaa!
Short, sweet and useful. Go raibh maith agat.
i'm installing a ceiling fan (my first DIY project ever is a little ambitious) and need to install the mounting brace, and man was i struggling to get those wood screws in!! i'm gonna drop by walmart tomorrow for a drill bit of the right size so i can finally cool down my room in this crazy heat
Let me know how it goes!
You’re awesome
Thank your posting this. I am going to hang up a hammock and need to pre drill to screw in by hand a 1/4in screw. Would the correct straight bit size then be 11/64?
The pre-drill size should be really close to the size of the screws shank. If the shank is 1/4" you can use a 1/4" and be fine.
In regards to the screw wax, ive recently found some brands that pre wax their screws. It certainly saves time on a job site. If you can find them...
Thanks for sharing!
I would add info about pre drilling for the sake of accuracy when using large drill bits too, not just when we are screwing.
My girl was watching this & thought he was screwing that in with his hand. Hahahahaha!
👍
Nice video, thanks! What is that screw was you mentioned?
Are you referring to "self-tapping" screws?
@@TrainingHandsAcademy Sorry, i meant the screw wax. Thanks for answering!
I was using this one in the video. amzn.to/39KI31r
If I'm screwing in an 8 inch screw, do I pre drill the entire 8 inches?
what brand is the screw wax you use, or will any surfboard wax be suitable?
amzn.to/3aBs3B2 .. and I think surfboard wax would work too!
What about drywalls? Same thing? Just match the size of shaft of the screw?
Yes. :)
How do I read the numbers on a packet of screws? 10-8 x 65mm, 10G x 75mm, what are these numbers and what do they mean?
The 10 is the diameter of the screw. Often times it is just called a "#10 screw" here in the US. The 8 is the TPI (threads per inch) and the last number is the length of the screw. The second screw is different in that it is galvanized, meaning it's coated for outdoor use. The middle number of the second screw is not listed, therefore it would have the normal number of TPI, and for a #10 wood screw, that would be 13 threads per inch. I hope that helps.
@@TrainingHandsAcademy yes and no I guess. Do any of these numbers tell me how what size drill bit I need to drill a pilot hole?
Let me know if you ever do a video at a hardware store and pointing out all the screw types and labels
The first number tells you what the diameter is... which then helps you to determine the right bit for pre-drilling. The actual pre-drill bit sizes come from a chart that you can download online, search for "pre drill screw chart size." For example, and #10 screw on the chart shows a pre-drill bit size of 1/8"
@@TrainingHandsAcademy OMG I got it now!
10 - 8x65mm
10 or 10G is the "Gauge" which is the diameter from thread to threat. Online charts show a 10gauge is 5mm.
8x65mm, 8 is the mm diameter of the head of the screw and 65mm is obviously the length of the screw which was the ONLY thing I understood before all of this.
So now, it seems I drilled the WRONG pilot hole!! Oh well lol. Thanks for the help.
I've always been told to just rub the screw on a bar of soap. How would you compare that to the wax?
I used soap as well when I first got starting in woodworking. I think the wax overall is better, how much better...? I don't know.
@@TrainingHandsAcademy Thank you for your advice, much appreciated!
I also wondered if pre-drilling too deep will undermine the screws ability to secure the two surfaces. Looks like the depth of pre-drilling isn't even mentioned. Am I to assume, you can pre-drill the entire length of the screw you intend to use? I will also assume you should never pre-drill deeper than the length of the screw?
I always wondered & worried about drilling too deep and now finally got around to asking.
Yes pre-drill entire length of the screw, and it's ok if you go beyond the length of the screw a little.
@@TrainingHandsAcademy Thanks for the quick response! I always wanted to know. Great video!
Does a pre drilled screw hold the same weight as the non pre drilled one?!
Great question, yes it does.
Counter Sync?
I'm opretar this machine
Learn something new again!
come to brazil
Never been
@@TrainingHandsAcademy we have trees
I went to pre drill and got my bit stuck in the 2x4 stud😅 No idea how I managed to do that but it’s still stuck and won’t come out lol
Been there! lol
Tighten your chuck and run it in reverse quickly.
So-called self-drilling screws don’t remove wood. They merely chew the wood. Splitting can still occur.
you look jhonny sins 😅✌
Great video but I will never hand drill a long screw like that, consequences be damned
I buy the same screws and just lube the whole box with WD-40. Drive a lot easier and saves battery life.
I need help 🤣
With what?
You said nothing about choosing sizes lol.
