Bronze Oxide Finish Drill Bits

Drill bits with a bronze oxide finish appear bronze or gold in color, and are best for hole cutting jobs where increased durability is important. This type of finish reduces friction, allows for easy recognition of, and increases toughness of the bit. It's most important on drill bits for cutting into metal, however you may see a bronze oxide coating on other types of drill bits too.
