When to use it
This のに means "for" or "in order to", and it is used with a limited set of words in the second half: かかる (it takes time or money), 使う (it is used for), いい, 便利だ, 必要だ, 役に立つ. It says how much something costs, how long it takes, or what something is good for: このはさみは紙を切るのに便利です.
Nuance
Neutral; common in daily speech. The main clause describes cost, time, usefulness or need, not a deliberate action. With a noun, に is used without の: 旅行に便利なかばん, 料理に使う. It is a set pattern, so learn it with these words.
Compare
Purpose のに vs ために: ために is followed by an action (家を買うためにお金をためる); のに is followed by an evaluation or cost (家を買うのにお金がかかる). Purpose のに vs "even though" のに: 30分 (to get there) vs 急いだのに遅れた (even though I hurried).
Tip: Tell the two のに apart by the second half: かかる, 便利, 必要, いい point to purpose; a surprising result points to "even though".
