The Mibro 5/16 in. 18 NC and 3/8 in. 16 NC Plug Taps are designed for cutting new or restoring existing internal threads in compatible holes. Made from quality tool steel, these heavy-duty plug taps provide durability for threading and repair applications. A titanium nitride coating helps reduce friction for smoother operation and extended tool life. The first 3 to 5 threads are tapered to help the tap start straight and accurately. National Coarse (NC) threads are a general-purpose thread pattern commonly used in machinery, equipment, and everyday fastening applications. This plug tap is ideal for maintenance, repair, fabrication, and general threading projects.

Seemed to be a store return, by the way the package was taped, it did work for what I wanted it for.

No, I do not recommend this product.
