VFM Excellent for its price. It drills without impact, but it takes more time that way. It's worth it, just like always you have to be careful not to hit iron because it can break the teeth. It has a large thread for SDS plus, such threads are found in SDS MAX, which theoretically makes it impossible to break like those with smaller threads. But that's not necessarily a good thing, because instead of breaking the thread, the tool may get damaged or the SDS may break. Who knows.

Very good when used with the appropriate hammer. It penetrated through solid brick without impact, only with rotation.
