I use this drill for several months, the traditional DIY: Drilling wood, brick / mortar and occasionally concrete and metal. Fairly light, compact and easy to handle, this drill is to use very pleasant to use, both single and percussion drill fashion. Powerful, it never failed me, even in concrete. The self blocking chuck system is great, simple and efficient. The drive is very convenient for delicate drilling boots. This is an excellent tool for DIY everyday and also for more serious work.
To get the best of this drill, do not hesitate to be equipped with quality locks and drills that even the best and most powerful of the world's drills will give poor results (or break) if used with accessories piercing (bits and drills) low end.
Also note that it remains a tool for small and medium business. It seems clear that this device is not suitable for drilling 10 hours for thousands of holes, 3 cm in diameter in concrete or hardened steel ... Each use his tool.
