You actually don't have quite that much (yet) - this is possibly the best high hand now, with a draw to the nut low.
If you have a strong draw to the high nuts, then sure, it's fine to come out betting.
The problem you will run into with this example hand is that you are most likely behind on the high side (you're not drawing to the nuts on the high straight - anyone holding 46 or 67 is way ahead of you) and if the hand comes brick-brick on the end, can you really win it with just a pair of Kings? I'd be surprised.
You generally want to bet to protect your made hand or give some deception to your nut draw. In this case, you don't have either, so I would be checking to see how the hand develops.
I agree with switch - if you have only the nut low, then betting is almost never the correct play.
