What is the toughest drill bit for metal?
Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades. Carbide (Carb) is the hardest and most brittle of the drill bit materials.

Can you use masonry drill bits on metal?
While wood and metal bits’ sharp tips are useless against concrete and brick, masonry bits’ abrasive tips quickly bore through rock-hard substances. On the other hand, masonry bits’ blunt, abrasive tips are largely ineffective at boring through wood and metal.
How Can I drill a hole in metal without a drill?
