My analysis of this Router Bit showed that the marketing is deceiving. It claims to have a tungsten engraving, but in reality, it is dull and ineffective. The only positive was the price, but it's not worth it for a product that doesn't work as advertised. Save your money and invest in a better quality router bit.
Pros
High-quality tungsten material for durable and long-lasting engraving results
Cons
Suitable only for specific sizes and degree of engraving, limiting its versatility for various projects
