I bought a set for measuring chamber sizes in revolvers I have. I paid $90 on Ebay about a year ago. It was the .250"-.500" they work great.

Good option... Pin gauge sets are expensive and I don't see my self using it that often. Seems like a quality drill bit set could serve a duel purpose! I like it!

Not really, note all the gaps in the required range...
(0.099 in.), 40 (0.098 in.), 41 (0.096 in.), 42 (0.093 in.), 43 (0.090 in.), 44 (0.086 in.), 45 (0.083 in.), 46 (0.081 in.), 47 (0.079 in.), 48 (0.076 in.), 49 (0.073 in.), 50 (0.070 in.), 51 (0.067 in.), 52 (0.064 in.), 53 - pin gauges won't have that.
Pin gauge sets like the ones listed by myself and @ar addict have a tolarance .001". Do you think a set of Harbor Freight drill bit will have tolarances like that? There are many uses for a pin gauge set beyond measuring your gas port size.

Do as you please but I stand by my previous statement here...

I hear you...your advice is not falling on deaf ears and is truly appreciated. I have always prided myself on being "the right tool for the job" guy. Just trying to balance cost of rounding out AR stall, starting up reloading from scratch in this market (or lack of) and tools to keep them both running... Money tree out back has it's winter coat on!!! Yikes

A round hole is a round hole.
Easy enough to measure the bit to see what it really is with some calipers.
Which is what I do no matter who makes it or what it's marked as. Always verify.

FWIW the bit marked .067" was really .067"
There are some gaps in a drill set but I lucked out I suppose.
I do have a .25"-.50 pin set but didn't see the need to buy more just to see what the gas port size was if I had a bit that worked.
All I wanted to know before dimpleing the gas block was the hole size and it worked for that. Didn't have to look very far for a 5/32 bit to dimple with either.

I love seeing people going back and forth about ways to measure a hole it's very entertaining. Yes a round hole is a round hole but I will tell you this a .067 drill definitely does not measure .067 that's just not how drill bits work. Pin gauges are great but you have to remember if a .067 pin fits the the hole is at least.0008 bigger or else the pin will not go in and that boys is why there are plus and minus pin gauges. Me personally I have much more accurate tools to use than a drill bit but if that's all you got go for it.
