Needed for a job to drill out a dumb drain valve on a water heater to replace with a high flow ball valve. This is 1/64" below what is actually listed for 3/4" female NPT but was about 1/4 the price of the size listed and did the job. So I didn't really "emphasize" that point, but it's edgy and was the right solution for my needs. Based on that, however, I would buy Neiko for more demanding needs as well.
