Beat 2 with this? (6)
I believe the answer is:
hammer
'beat' is the definition.
(hammering is a kind of beating)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hammer that I've seen before include "Clawed tool?" , "Carpentry tool" , "Nail-driving tool" , "Small ear bone" , "Weaken, damage" .)
