Review on QUALITY PRECISION BORING DIAMETER CARBIDE by David Lucas

This boring bar is a complete waste of money. I work in the Industrial and Scientific field and have extensive knowledge in Cutting Tools gained from practical experience. This boring bar was an absolute disappointment. The precision and quality of this tool is severely lacking. It couldn't even bore a clean hole through a soft metal without leaving a rough finish. The only pro I can think of is the carbide material it's made of, but that doesn't justify its poor performance. Don't waste your hard earned money on this subpar product.
