Frequently Asked Questions (FAQs)
1. Is there a drill bit that goes through metal?
Regular drill bits can't cut through steel, so you need a heavy-duty, hard drill bit to do the job. There are two types of drill bits that you can count on for metalworking projects: titanium and cobalt. Titanium drill bits are high-speed steel drill bits (HSS) that have a titanium oxide coating.
2. What is the best drill bit for drilling through metal?
Cobalt drill bits are the best drill bits for hard metals including stainless steel. If you are using a hand drill then a 5% (M35) drill bit will be most suitable and it will be less brittle than other drill bits. TTP HARD drill bits are 5% cobalt and are a high quality drill bit.
3. What is the hardest 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.
4. What is the correct tool for boring holes on metals?
Almost any general-purpose twist bit will do a decent job of drilling holes in metal. In fact, most drill bits for metal are manufactured to drill through a variety of materials, including wood and plastic.
