• Speed: The speed of an impact drill is measured in revolutions per minute (rpm). A faster drill will be able to drill through materials faster, but it may not be as powerful.
• Impact rate: The impact rate of an impact drill is measured in blows per minute (bpm). A higher impact rate will make it easier to drill through tough materials, but it may also be more noisy.
• Weight: The weight of an impact drill is important if you will be using it for extended periods of time. A heavier drill will be more powerful, but it will also be more difficult to maneuver.
• Price: Impact drills can range in price from a few hundred dollars to over a thousand dollars. It is important to set a budget before you start shopping so that you do not overspend.
