Machinist here. Everything you said is true, stainless will work harden. You need plenty of force to make the drill bite into the metal. As the drill is cutting its also creating a small hardened zone...you need to cut beyond that zone as the second flute comes around. Not enough pressure and the drill rubs creating heat and dulling the drill. Put a whiff of dish soap in the water helps even more.

Inorder to maintain some water retention around the hole that you are drilling out, make a water dam around the hole, using some plumbers putty. This will usually hold enough water in place, for the whole drilling process. Thanks for all of your videos. ❤️❤️❤️❤️❤️❤️ Keep your screws loose, and your holes tight.

You have got to be kidding me !. I'm 65 years old and have worked with all metals never heard of this. Thank you Sir for shedding the light.

Thank you Captain... If not for your video, I would be making all those mistakes you mentioned... like using lubricant instead of water, high speed instead of low speed, expensive drill bits instead of ordinary bits. Good video, a must watch for all. Thanks for sharing.

Thank you for the tip👍I learned this as a kid from masson drilling in stones, concrete etc. I use a small container of cold water on the side 💡❗

Thank you very much. I have to cut some 16 Guage stainless steel, and now I won't burn up my drills, and Jig saw blades😊😊😊

Glad I found this!! I had to drill a decent amount over the past few days on a project. I would have went at it full speed, no water. This technique made it quite easy. Thanks!

Thanks for sharing this. I'm at my wits end trying to drill those stubborn stainless steel box in my garage and even broke several cobalt drill bits doing so.

Thanks for the stainless cutting information. Very much appreciated it.

I’ll tell you why I appreciate this video. It teaches you good drilling technique. In actuality you don’t need expensive drill bits although they make the job faster and are more friendly to drilling too fast. If you know what your doing cheap drill bits will drill through almost anything. I bought a set of the cheapest drill bits I could find, even cheaper than harbor freight and I still drilled through a grade 8 bolt easily just to prove a point. Now it took longer and I drilled slower than with my nicer bits but it did the job without dulling the cutting edge at all

Wow this forreal works. Doing it now and the holes are coming out so so so much faster than in my past using rapid tap. Thanks so much!!!

You convinced me with that sabre saw demonstration.

Very helpful! Thanks, Wayne.

Wasn't looking forward to a job I have to do tomorrow. Now more confident. Thanks.

Many thanks for the tips and the music!

I love learning from experts...great video 😄

Thank you for this video. Very helpful.

That's good to know. I wished I saw your video sooner, would have saved a lot drill bits

Thank you for all the helpful advice!

Thank you , - straight and to the point , YOU ARE AWESOME ! , made my project go easy and cheap.

great advice i came to youtube to learn about drilling metal and sharpening drill bits and i think ill be trying this myself in the future :)

Ace Wayne, really helpful!

Thanks for making this, I’ve been trying to drill some 1.5mm thick stainless plate and had the issue of getting it too hot and ended up with a dull drill bit, gonna give this a try.

The water is serving as a lubricant, but as you mentioned, it serves as a great coolant. It takes a lot of heat to flash water into steam and oil doesn’t go through the same phase change as water and it is the phase change that really absorbs the heat.

Thanks for the great tips. I hate breathing in burning oil smoke...I do prefer using a drill press whenever possible. That way you have more control with a free hand.. Great video

Thanks Wayne. I broke 7 bits yesterday trying to drill 4 mm 304 stainless. Then watched your video. Drilled 16 holes today with a cheap drill bit, no problems.

Good info! I used your “TIPS”. Worked great

Thanks for the tip. Very helpful

Great tips. Thank you for sharing.

Great tips, thank you so much.

Awesome trick. Thanks buddy!

Hey gang, your not only keeping cutters cool, your keeping the stainless cool. Heat will work harden it in a hurry. The hotter, the harder.

Great job!

Thanks for the excellent tip!

I did this with stainless steel and titanium, the water works. Made holes in both with no problems, thanks.

watched a 3 other how to drill SS video,didn't work for me,your advice is gold!1.6mm 304 SS sheet,around 1 minute with cheap drill bits.I used small bits first as other video suggested, didn't work,your advice of constant preasure is the key,soon as the bits start to bite,you know you are almost there.sum it up:slow,constant pressure,dip in water.

Great tip, thanks. Tried all types of bits on my very very hard s/s, and nothing worked...then tried Dewalt Extreme 2 (need to use larger than the 5mm size as these have special flat end) and worked a dream. Slow speed, medium pressure, loads of water spray, and went up in increments to be on safe side (probably over cautious). These bits make all the difference. Try them for yourself.

Yep as an electrician I used to always use water or even spit when rotohammering concrete. Keeps the bits from over heating.

great video. Thanks!

Most excellent instruction. Works great!

I read the comment section, ya, we’re all here for the same reason, I got to drill through 1/4 “ chain plate on my boat, been putting it off, good video

Great info. I have to drill through stainless, but I think I'll drill through an ice cube and leave it on the drill bit while i'm drilling. We'll see if that works.

Very helpful for a beginner like me.. Thanks!

Thanks for this great idea

Incredible video! Thanks

Excellent video!

Wonderful video. Thank you

Thank you. This solves the problem I was having today.

You're a good man, Captain.

Wow what a good tip, thanks.

The coolest part of this video is the word, "Snook" found on the bumper sticker beside you. Great sports fish.. a real fighter & OMG after they've been cleaned & de-boned you're left with steak size fish strips for preparing however you choose. Personally I've always liked 'em breaded & deep fried. Yum Yum!

Yes. I found this video useful. I drill through stainless steel pipe that is used to weld two copper pipes together. Three drill bits busted. Today, 6 November 2018, I shall bring a squirt bottle to work.

It's hard to believe but it's logical. Nice tip. I must try ir.

Captain Wayne! I was hesitant to use water on my milling machine to drill some hole in stainless steel…tapmagic wasn’t hacking it. Switched to water and magic! Thank you very much for the suggestion!!!

It works! Great tip yet!

i search all over youtube you tip is best one

I reckon I am one of the few who like stainless steels especially the 300 series. It is clean the coolant doesn't get full of crap.

Well done!

Great tip

Thanks for your tips

Great video. Thanks for the info.

This one really helps my project a lot in which I have to cut a stainless-steel kitchen pepper shaker in half.

Thank you.... Very nice video

Thank U so much for this video ....🙏🙏🙏

Thanks for your beautifull tips 😀

Great video, if you want to trial our TTP HARD cobalt drill bits and CUT-IT metal cutting paste some time let us know and we can get some sent straight out

Great tip! Thanks...

Nice...thx for this handy tips

I wish I could give you two thumbs up instead of just one thank you I learned something today

makes perfect sense, and best of all, it works.

Very nice& effective demo...

top man, I know what i need now , low speed and water only

Great man !!

You are correct. Worked as a machinist years ago. Stainless is low speed and high feed for sure.

thanks, very nice video

Brilliant, thank you!

I did not know that thank you excellent video

Thank you. Im going to drill a fairly small pan. I think I will place it in a plastic tote with water.

great vid, thanks

“Cool” tip. Thank ya man.

Thanks for the great guide I have to drill some holes in a set of stainless boxes and cannot keep the drill vertical due to the nature of the boxes. Any idea how to lubricate in such a situation? Thanks

I broke 4 bits today at work and am at risk at developing a nickname. Thanks for this video.

Great video thank you

Very good vídeo thanks 👍👍👍

Good advice. I tried this and it kept the drill bit sharp and cool. Thank you.

Thank you Sir, it really helps

I like how I find this AFTER I figured this out on my own through trial and error milling 304! smh 😔 Great video! 🔥🙌

A couple of things that help are using 135° point angle, and do your best to keep a chip going. If you need to stop, you will need to break through the hardened layer to start a chip again. Ive had much success using a 135° cobalt split point bit for a pilot and then going continuing on with regular hss. Ive had to go as large as 1" and 3.5 deep using this method, water works well, but coolant is better, has a high water content for heat control and still offers good lubricity.

Thank you so much.

Very useful information

thank you

Nice ! Thanks !

Great tip. I'm planning on cutting a 1mm 316 steel sheet using a jigsaw. I might clamp it to a sheet of sacrifical MDF while cutting. I wonder if it would be helpful to drop a bunch of icecubes into the water, to keep the water cold until used.

Good tip. I like Rapid-tap but it's pretty expensive (and stinky) since you go through a lot of it with stainless. I'll have to give straight water a try.

Thanks You Sir for Your Tips.

I am a newbie, so, thank you, thank you, thank you.

I drill stainless everyday. Agree with the water. Oil is actually worse than not using anything. One thing I will say. When you start drilling go with it. Don’t peck at it. Drill it. Stainless work hardens quickly. I buy the cheap drill bits and they will last a longtime if you drill it when you start drilling. If it does work harden you will have to heat it up with a torch to an orange and let it self cool before drilling it.

Thanks I used nearly four drills before drilling using oil lubricant and took a long time

Hi Wayne my name is Jim mungai I’m from Canada Pennsylvania in many years ago I worked for the Boeing company building parts for a commercial airliners anyway snow and then head to drill some titanium or cut do some Connor sink work van same theory applies lower and steady pressure even with the carbide drill bits are you had to go slower and not overheat that titanium or it will work hard in on you like right now anyway but thank you for that information I never knew about using water like that for stainless thank you again again this is a Jim mungai From Kennerdell Pennsylvania

I took a whole week to drill hollow SS pipe. I wish I could've known this before.
