Frequently Asked Questions (FAQs)
1. 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.
2. What kind of bit do you use for metal?
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.
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. Do diamond bits work on steel?
While diamond drill bits are designed for drilling in extremely hard materials, Electroplated Diamond Drill Bits are NOT designed for use on metal, concrete or masonry materials. For drilling in concrete, masonry, and metals such as iron, cast iron and steel, a carbide tipped drill bit must be used.
