Review on High-Performance Brad Point Drill Bits in Inches by Steve Tarantino

The drill bits I purchased in this category were a complete waste of money. The first issue was their inability to consistently create clean holes in any material. As my tests showed, they leave rough edges on the holes I made leading to shoddy work. The only positive was the range of sizes in the set. But, overall, I would not recommend these to anyone in the Industrial and Scientific field.
