Q: Sizes 1,2,3,4,5 are imperil/standard (1/8, 3/16,1/4, 5/16/, 7/16) are the half sizes metric?

Center drills are intended to be used as starter drills before drilling the final hole size. After center punching where you want to drill a specific hole size then use a center drill to start with. They are also used on a metal turning lathe to make a center hole for the live center that holds the stock that is going to be turned. As far as the sizes that is just for reference. I’ve been a machinist for 40 years. These work great for home use to start a hole.

Q: Ok, I have a Unimat mini lathe and there is not enough for regular drill bits, do they make short drill bits the length of these center point drills

There are stubby drill bits you can buy.

Q: Can this be used in reverse to extract a snapped bolt?

No. You need a screw/bolt extractor bit for that.

Q: can these be used in a size 3/8 cordless hand drill?

Probably, but won't work as well as a set of countersinks that are made for a handheld drill. About the same price.

Work great

Just got a mini lathe as a hobby, trying to get some tooling put together, these are cheap enough to learn with. Used one of them to center drill this, then dill a hole threw a bolt for a plumb Bob

Be very careful and you're OK

Small bits have a tough time in brass and don't work very well in steel. The bigger bits work great in everything though. Hog through metal with ease and leave a clean cut.

Works but could be better

The product is okay. While it is sharp enough to cut, it's simply not durable for fast center holes. I was feeding at 4 ipm and it broke going .04 deep in mold steel at 1500. Packaging looks nice.

Necessary tools for lathes.

This set of center finders covers all sizes of countersinked pits in my project work pieces. They are extremely accurate and durable for a good price.
