what I learned from the old boat maker who uses the marine grade hardened stainless steel is: 1. put the material in the freezer and take it out seconds prior to drilling 2. put one or two ice cubes on the material as near to the expected hole location and it can touch the drill bit on the drill press just be careful with your fingers or use small piece of wood to push the ice cubes towards the drill bit 3. use high temp car engine grease (red paste) and dip the drill bit in it, it will remain on the bit as it's very sticky 4. use cobalt drill bits preferrable with the narrower pilot tip (DeWalt or Bosch or alike) 5. right after drilling, drill through another ice cube and leave it on the drillbit end with the above method, I can actually push hard on the material, and drill quickly, the quicker the better. the chips will be like a spiral continuous cut rather than smaller shorter pieces. I also use the aluminum drill press table that dissipates the heat from the drilled material. and it is waterproof / oil proof, so it's a breeze to clean up the mess, comparing to doing it on the wooden drill press table. cool video shooting with the action cam underwater.
Thanks ! Yesterday I discovered myself water is doing the job for stainless steel at low speed (I was grinding a hole). Learned in the hard way after destroying couple of drills and stones. I wish I knew this video exist.
Thanks, glass and s.s. are the most pain to drill, by far- so true. What's the rpm (setting on the adjustable drill)? Stainless, chipped my cobalt bit (cobalt bits, especially the thick ones are very expensive). God bless, Rev. 21:4
There is no electrical hazard to drilling that stainless in a bucket of water with a corded drill (unless of course, you stand in the bucket and drop the drill in the water also)

Great advice-it worked awesome-much thanks! I went a step further and added ice to the water and put the SS in the freezer before drilling.
Cheers
thanks, being able to drill stainless steel opens up so much more DIY possibilities
The go pro shots are class!!

Great tip using aluminum as a heat spreader! Will give that a try tomorrow at work!

Hey Alex, Glad to hear the video is helping you out, It’s crazy how just some water can be so helpful!
use a normal metal drill bit, just water to cool the bit, no need of expensive tips or special oil.
Nicely done video.
loving all your videos! the format of them is so entertaining :)
great video thank you
Useful video. Thank you.
Very useful, thanks!

Stainless, chipped my cobalt bit (cobalt bits, especially the thick ones are very expensive).

Hi Steven, I just have my drill set to the slowest rpm and use the trigger to get the speed I want, sort of like clutch control in a car. Thanks
Good idea

They are Titanium drill bits not Tietanium!
Not where I'm from!
