just wondering what is a good size bit.

ag4l,

What do you use it for? Drilling all the time? Only to pop bullseyes on long cracks? Give us a bit of info on your intended use, and someone will let you know what they like for that application.

[Delta Kits]

You mean popping bullseyes on long cracks, correct?

[GlasWeldTech]

Get Delta's FG-701 as good as any I have used.

If you're using them to pop bullseyes on long cracks, I would recommend the FG-701 (if you're going with a DKI product), as GlasWeldTech said. It's not the smallest, but it wears quite a while, and drills a big enough hole to get your probe down to pop.
