Minecraft wiki entry for Breaking, associated text: For example, a player with Haste II holding an Efficiency V diamond pickaxe can break stone instantly, as the damage is (8+26)×(1+0.4)=47.6, which is greater than the base hardness of stone (1.5) times 30 (which is 45). Players in creative mode always break blocks instantly regardless of tools or status effects, except for when wielding a sword, debug stick or a trident, in which case the player is unable to break anything.
