Metalworking drill bits require something different than typical multi-purpose or wood bit sets. Due to the harder materials, drill bits made for metalworking come in titanium nitride, tungsten carbide, or cobalt high speed steel. These denser metals can resist the toughness of regular steel, stainless steel, and aluminum as well as the greater temperatures and abrasion. Cobalt HSS is common for heavy metalworking using cast iron, bronze, and cast steel as well. As a result, drill bit sets that come in cobalt HSS will be more expensive than other options but will be the best for a high-quality, lasting set.
