I have a 7.5 amp motor hammer drill. This hammer drill takes me 40/45 minutes to drill a 3/8" hole 2.5" deep, drilling into beach rocks. It take me a few seconds to drill the same hole into concrete.
How much (many minutes) faster would a 5.2 Amp SDS Plus Rotary Hammer, 2920 blows per minute do the same hole into the beach rocks?
TIA,
kurango
