Although it was work while using stainless steel drill oil (product number: 854) purchased together, Nachi 3 mm 6 mm even with Makita GHP 451 Hammer drill 18 V 3.0 Ah, teeth did not stand at all and asked a trained motorcycle repair shop and asked for a torque We used a gold bit set and a drill oil 854 which seemed to be expensive with a heavy metalized heavy coded drill and also scoured up to the point of penetrating smoke while using it, but we watched the state while holding down the motorcycle carrier , Gold bit was better than NACHI. After that it was penetrating & finishing with 9 mm of NACHI and smoke with oil. Perhaps, it felt like I got a piece of cheap gold bit 9 mm if it was two.
