Why Titanium Coated Twist Drill Bit?

Titanium-coated stainless steel can come in heavy gauge sheets because it is a thin layer of titanium chemically bonded with a thicker layer of stainless steel. Stainless steel coated with titanium may increase its scratch and corrosion resistance, making its durability superior to many other metal options.
