The corded hammer drill is a powerful beast. For powering though hard materials like concrete and steel the best hammer drills need at least 500W of mains power to generate sufficient rotation speed and hammer action. Look for corded hammer drills that come with a variable speed trigger and no-load speeds in the 0-3,000 rpm range and impact rates of 0-48,000 bpm (beats per minute).
One of the most important features of any drill is how far it can penetrate. The best hammer drills should be able to drill at least 25mm into wood and 13mm into steel using the drill’s rotary action and at least 13mm into concrete using the hammer action. Look for a chuck size on a standard hammer drill of 13mm. These drills come with keyed or keyless chucks – keyless are more convenient.
Comfort and ease of use are important features too, especially if you are using the drill for long periods. Most hammer drills weigh around 2kg, but a secondary handle, ergonomic rubberised grips and low noise and vibration levels will all make a positive difference to your drilling experience.
