What is the best drill bit for galvanized steel?

What is the best drill bit for galvanized steel?

Clearly, the best drill bits for hardened metal or steel come with a cobalt blend. These cobalt drill bits use an alloy including 5%–8% cobalt. This cobalt makes up part of the steel blend, so the hardness of the bit doesn’t wear off with a coating (like titanium bits).

Can you drill thru galvanized steel?

Drilling into galvanized metal is no different than drilling a hole in standard carbon metal, with the exception that the protective zinc coating does not protect the drilled hole. This can cause corrosion (rust) to form in and around the hole.

Are cobalt drill bits better than HSS?

Cobalt drill bits are incredibly strong. They can be operated at much higher speeds than a standard HSS drill bit. The ability to withstand heat means that cobalt bits perform for long periods without cooling or the need for cutting fluid. They are most often used to cut through hardened and abrasive materials.

Which is better black oxide or titanium drill bits?

I’m sure that you won’t be surprised when I say that titanium bits have a significantly longer tool life than black oxide ones. Compared to a bright finish bit, a titanium bit lasts up to 6 times longer. In other words, if you want to get the most value for your money, titanium drill bits are the way to go.

What are the strongest drill bits for steel?

carbide-infused drill bits are one strong option when drilling into stainless steel. Infusing drill bits with cobalt is another way that manufacturers achieve ultrahard drill bits. High-speed steel, also known as HSS, is the most common drill bit for metal applications. Cobalt bits are an extension of HSS bits.
