Drilling and cutting stainless steel. 

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

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.

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!

You convinced me with that sabre saw demonstration.

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

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.

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

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.

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!!!

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

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

Many thanks for the tips and the music!

I love learning from experts...great video 😄

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

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.

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.

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

Very helpful! Thanks, Wayne.

Thank you for all the helpful advice!

Thank you for this video. Very helpful.

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.

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

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.

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!

You're a good man, Captain.

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

Great tips, thank you so much.

Thanks for the tip. Very helpful

Most excellent instruction. Works great!

Awesome trick. Thanks buddy!

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.

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

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

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

Thanks for the excellent tip!

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

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.

Great tips. Thank you for sharing.

Very helpful for a beginner like me.. Thanks!

Great job!

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.

Brilliant, thank you!

great video. Thanks!

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

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

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

Incredible video! Thanks

Thanks for this great idea

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.

Wow what a good tip, thanks.

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!

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!

Stop and start the drill bit with a lot of force. Pull the trigger like you would a gun. Pull the trigger and let go, pull it, then let go. The action of the starting and stopping, digs into the stainless like I have never seen before. Short coils coming off and the drill bit does not overheat. Never ever hold the trigger on with stainless steel. The bit will dull almost immediately. And yes, water is the best lubricant for drilling stainless steel.

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

i search all over youtube you tip is best one

Excellent video!

“Cool” tip. Thank ya man.

Great tip

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

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

Well done!

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

Thanks for your tips

Wonderful video. Thank you

Great video. Thanks for the info.

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

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

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

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

Great tip! Thanks...
