Is there any way to use a 611 such that it accommodates other sized drill bits other than 1/8, 1/4, or whatever collet size you happen to have? There’s a lot of drill bit sizes smaller than 1/8 and between 1/8 and 1/4.
Thanks!
Just one example of many different brands…

Duh, hex bits. Never thought of that. 
thanks! {slap forhead}

Even on the lowest setting the spindle speed of 16000 RPM is too fast and you will be damaging the drills and or your project.
You’re better off using a V bit to center drill the locations and then finish them up on a drill press.
I have a project that requires a 150 holes to be drilled. Hoping I can get by with the spindle. Sorta need precision.
Any software you could recommend?
Jon,
of course I don’t know what you are doing or how many you need to make, but you may be better off getting a carbide bit made of the right size and a 1/4 inch shank.
Or who knows, you may get lucky and find one off the shelf.
please dont put these in your collets lol they will not work and you will damage the collet
If you must use harbor freight at least get these http://www.harborfreight.com/14-in-high-speed-steel-spiral-cut-bits-3-pc-61583.html or these http://www.harborfreight.com/18-in-high-speed-steel-spiral-cut-bits-3-pc-61633.html
Ok Guys, advice heard. No drill bits Didn’t expect this to be a big topic hehe.
@JonGlazer
on the contrary though you can use all sorts of drill bits with a cnc machine
but usually you have to have a er series collet system for them to work
you can use things like these
thats how I drilled all of these
you you can use these

and its best to mount a drill to your spindle so you can go at slower rpm speeds
Jon,
I drilled both sides of this disk (~2,000 holes) with this 1/8" bit with no issues.

I bought this kit for future projects. Includes brad bits for 1/8", 5/32", 3/16" and 1/4" (1/8" Shank on all bit sizes).

I’m a bit confused. How would one mount their drill to a spindle?
I’m not being sarcastic, I truly do not understand.
Well professional cnc machine have what they call drilling banks or blocks and basically they hang off to the side of the main spindle and are used only for drilling holes
But like for example on the x-carve if you built a custom mount or even zip tied a drill to the router you would be doing the same thing

Ahhh…
...I have found another Master Jedi to compensate my learning under. :-DWhy not just use the Drill option in Fusion 360?
Any milling bit smaller than the desired hole size can drill any hole desired.
because endmills are not designed to be used as drill you will go through then rather quickly
and interpolating a hole smaller than .25" is a slow process with tiny endmills
