Buying Guide Image

Frequently Asked Questions (FAQs)

1. What is the best drill bit for hardened 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).

2. Which drill bits are for steel?

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.

3. What tool is used for boring holes in metal?

Hole Cutters Also called hole saws, hole cutters are used to cut perfectly round holes in metal, wood, and other materials. These metal working tools can cut far larger diameters than your standard drill bit.

4. How do you bore a hole in steel?

Drill at a Slow Speed 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.
