Reliability rating of rotary hammers - comparison of the best models for home and professional use

To select a good power tool, it is not enough just to study its technical characteristics, because even a powerful and multifunctional device in operation can show itself far from the best side. This rating of drills for reliability, is based on first-hand reviews - those who have been using these devices for many days and even know about minor flaws, or lack thereof.

Rating of punchers in price and quality

The best home punchers

Since home punchers are purchased for periodic and often short works, the requirements for them are relevant:

  • the device should be compact enough not to take up much space during storage;
  • power sufficient for at least short work on strong concrete;
  • reliability (the ability to periodic work in the "wear" mode) - you can not use the punch for several months, and then start a full-fledged repair;
  • the presence of additional functions - mode switch, reverse, speed control - all of them are useful in any case.

All devices that fall into the rating of punchers for home, without fail comply with the listed requirements.
