Black Bronze oxide coated HSS drill bits have a finish designed to help resist corrosion and they offer superior durability and speed.  Many pros find they get years of use from them and consider Black Bronze oxide bits the best general-purpose drill bits you can buy as they can have a 50% longer life than standard high speed steel bits.

Manufacturers heat the bits to 950 degrees Fahrenheit, creating a black oxide finish that resists rust and corrosion. This reduces friction between bit and workpiece, thereby speeding up the drilling process and have a decent heat resistance.

Black Bronze oxide drill bits are ideal for hard and soft metals but mostly used for drilling in aluminium and tough metals such as stainless steel but are also suitable for work on mild steel, copper, brass, wood, MDF, PVC, polycarbonate, acrylic, ABS, nylon, and composite materials.
