Sanding Drill Bit - How to Discuss

Sanding drill bit

What type of drill bit do I need for metal? Normal drills can't cut through steel, so you'll need a strong, solid drill bit to get the job done. There are two types of drills you can rely on for metalworking projects: titanium and cobalt. Titanium bits are high speed steel (HSS) bits coated with titanium oxide.

Which drill bit is stronger carbide or cobalt?

• Cobalt is better, but a good HSS drill will work if it comes from a quality source.
• keep them sharp. Most drills aren't as sharp as they should be, even right out of the box.
• Metal split points are the way to go. Prevents the bit from moving.
• Use cutting fluid.
• Let the drill cut, not the pressure.
