What To Look For in a Corded Hammer Drill
The corded hammer drill is a powerful beast. For powering through 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. Corded hammer drills that come with a variable speed trigger are ideal. They should feature no-load speeds in the 0-3,000 rpm range and impact rates of 0-48,000 bpm (beats per minute). If you are looking to carry out regular heavy-duty work an SDS hammer drill may be more suitable.
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. The chuck size diameter on a standard hammer drill should be 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.
