How to drill a NEW air hole?

[emus]

Did you clamp the caps when you drilled them? If so how did you do it so that you didn't scratch the cap?

I have a drill press and clamp.

Safety glasses.
Punch pilot hole guide dimple.
I tape cap to avoid scratches.
I use 1/4" plywood scrap against jaw faces to avoid scratches.

Since we have discussed the various types of drill bits, I have a question about the the various types. Of course the interest would be in a bit that can stand up to drilling stainless steel.

From the Precision Drill site they say that they offer bits made of: "cobalt, High Speed Steel (HSS) or solid carbide". So which type would work best for drilling stainless?

I have found 135° HSS bit to work best for drilling SS... They are a heavier duty bit vs. 118° bits you find in a standard drill bit set. They don't caost all that much more either.

Ya soooo broke a bit... Couldn't keep it straight so i put it in a rubber dog toy and drilled through that, bit snapped off in it when it hit metal...

Gotta concentrate keeping drill vertical and hold teeth just right when not using drill press.
Already have a pilot hole?

Like muzichead, I favor a 135⁰ bit for stainless. I'll go with HHS as long as it works; otherwise, cobalt. In all cases of difficult or work hardened material, I'll thin the web if the bit is big enough to see what I'm doing. Solid carbide bits withstand the heat of drilling plastics and composits, but are going to have a very thick web. For anything involving e-cigs and their modification, I would stick with plain high speed steel bits.

A hole is created by removing matter with the aid of a drill. Adhering to all the safety precautions posted previously, proceed to remove matter till hole of desired size and depth. Observe hole to determine nature of hole :
- if it fills with air , it's an airhole
- if water accumulates in it, it's a waterhole ( not to be mistaken with a watering hole - water is the least encountered fluid in these )
- if **holes assemble in it, it's a capital...

This is the bit I bought for rba cap air holes. Delivery was about 2-3 weeks. Have not used it yet because FT RBA order rejected by HKP.

Nope, hence the "NEW" in the title. I'll borrow a vice from someone later.

I understand it was "NEW" yesterday but naively hoped you made a little progress before snapping bit.

I actually have that same drill press vice. I'll give that a try on the Igo cap that I got from Fasttech that came with one hole. Thank you for the rundown.

I bet that I can get exactly that at Fastenal. I looked at H. Depot tonight and the guy there recommended a cobalt bit.

Indeed, Jerry. Fastenal is many times more likely to have quality industrial supplies.
