Tired of running multiple water filter systems


 
And the gold titanium step bits at HF work great.
Irwin, Hilti, Bosch are worth the extra for a long haul bit, but for most the HF bit work.
Just lube it or it will dull esp on SS.
Did not buy one yet. Good to know. Likely will be a one off project so i kinda hate spending $50+ for a thing I will use one time
 
And don't run your drill at high speed.

When getting close to the size hole that you need, take your time and only do 1 step at a time and measure between steps since you can't reverse the drill and make the hole smaller.:oops:
I kinda figured this. It takes a 1" hole so do these type bits make a hole bigger than the rated bit size? Or can I count on getting a 1" hole?
 
Anything but cobalt or carbide will probably be destroyed cutting stainless steel - so don’t expect meaningful use of the steps after you’re done

I used this for extracting some stainless bolts that had sheared - easier to use since it stays put but maybe not any better than regular oil

Mach-Blue 6 Fluid ounce(s) Multi-purpose cutting tool lubricant
Would a little high temp moly grease work instead?
 
Regular oil will work but you will need to keep applying it

This blue stuff globs on and you can go longer before adding more
Well I am likely going to have to do this all by myself so I'd like to be able to have something "cling" to the work. And honestly if the bit is rendered useless afterward I don't care. I rarely do this type of work
 
From experience from my bits, the drilled hole is the same size as the marking provided you have the bit squared up.
Excellent! Great to know. I guess even if it went slightly over not a disaster as there is a large escutcheon on it so there is likely MAYBE 1/16" leeway there anyway.
 
You'll feel each " step " as the bit goes down.
Starting from 1/2" just count the steps until you get to 1"
Usually they are spaced 1/16" or 1/8".
If you have a piece of scrap sheet metal do some practice runs to get a feel for it.

Yeah, I have never used one of those bits so it's gonna be a learning experience :D I guess I could look for a a 1" twist drill with a turned down to 1/2" shank. Then there is no doubt on the size
