Review on Chicago Latrobe Cobalt 15 Piece Increments by Aaron Hawk

When I tried these industrial and scientific cobalt drill bits, I was blown away by their durability and precision. THEY cut through metal with ease and maintained their sharpness over a long period of use .The 15-piece increments set also provided a variety of sizes to choose from. The only downside is the higher price point compared to other drill bits in the market, but the quality definitely justifies the cost..
