Overview
Sized to cut 3/4-10 NC threads, the Century 97117 is a high carbon steel threading tool weighing 3.84 ounces, rated 4.6 across 411 reviews.
The size notation 3/4-10 NC (3/4 inch diameter, 10 threads per inch, National Coarse) marks this as a single size threading tool rather than a multi piece set, and its light weight fits that reading. High carbon steel is the standard material for this kind of cutting tool, built to hold an edge through repeated use on fasteners at that exact size.

Who it's for
Machinists, mechanics or DIYers who need to cut or clean up 3/4-10 NC threads specifically. Not useful for any other thread diameter or pitch, since this tool is sized to that one specification.
Strengths and trade-offs
Drawn from this product's published specifications.
- Sized precisely for 3/4-10 NC threads
- High carbon steel construction
- Strong monthly repurchase volume
- Only fits one thread size, 3/4-10 NC
- Listing does not specify tap versus die
Performance notes
High carbon steel holds a sharper cutting edge than mild steel and resists wear better across repeated passes, which matters on a tool this specialized since it is built for one thread size only. At 3.84 ounces, it stays light enough to work by hand rather than requiring heavy tap wrench leverage.
