Based on my experience using this drill bit, it excels in both accuracy and efficiency. The bright finish allows for easy identification and the precision drilling is unmatched. The only downside is that it may be too expensive for some budgets. Overall, this high-quality drill bit delivers results you can't get from cheaper alternatives.
Pros
Efficient drilling due to its bright finish
Cons
May show signs of wear and tear sooner than other drills
bits of excellent quality! Wrong size sent wrong (looks like Revain didn't hide the correct supplier label properly). I contacted the supplier on Christmas Eve and was quickly put through to a real person who quickly resolved the issue, although it was obvious it was Revain's fault.
Some sanding dust on the preservative supplied but the edges are nice and sharp no chips or anything. Looks good, wish it had a # engraved on the bit - although this is unusual for small sizes. If you don't know the size, you may need a chart that shows the size of the drill bit versus the likely size of the hole. and not one or the other as some think.
