Hammer Drill vs Impact Driver | What Tool Is Better And When
Aug 28, 2022You can see speeds of up to 3000 rotations per minute from the impact driver, while the hammer drill remains at the 2,000 range. However, when I used bigger loads like the 1/4" ledger screw, the hammer drill was about 3 seconds faster than the impact driver. Therefore, the hammer drill takes the win for heavy-load operations.
