What are the best bits to drill through 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). It runs throughout the entire bit.

What is the best way to drill hardened steel?

In general, it's a good idea to drill through metal using as slow a speed as possible using a drill bit for metal. Hard metals like steel and larger drill bits require even slower speeds. With a small twist bit (1/16 in. to 3/16 in.), you can drill through most metals at 3,000 rpm.

How can you tell if a drill bit is for steel?

The Color of High Speed Steel You can distinguish an HSS bit by its black color -- a conventional steel bit is chrome. If you're drilling through hardened metal, even an HSS bit can wear out quickly, and you may need one made from tungsten carbide or titanium.

Are black oxide drill bits good for steel?

Black Oxide Drill Bits – Basic and Inexpensive Bits made with a black oxide coating are suitable for work on steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon, and composite materials. Black oxide bits last up to 50% longer than standard HSS bits.
