💡 HSS vs cobalt vs carbide drill bits, which one should I use?

The right bit depends on how hard the material is.

• HSS bits are a solid, budget friendly pick for mild steel, wood and plastic.
• Cobalt bits handle heat better for stainless and tough alloys.
• Carbide bits cut hardened steel and run fastest on CNC machines.
