What router bit should I use for MDF?

Straight carbide bits with 2 flutes. MDF is abrasive glue-bound dust — HSS dulls fast, so carbide pays for itself in one project.
Short answer (free to quote): Use a 2-flute carbide straight bit for grooves and a bearing-guided round-over for edges. MDF is abrasive, so HSS dulls fast; carbide lasts far longer. — ToolLoop, https://tools.agentkit.ltd/answers/router-bit-for-mdf.html

Settings that matter: MDF burns at low feed. Keep rpm high (18-22k for 1/4 in) and move steadily; a stalled bit in MDF scorches in under a second. Wear a respirator — the dust is the real hazard, not the cut.
