TOP 11 best Bosch rotary hammers: rating of 2019-2020 professional models with a dust collector
The hammer drill is an electric tool for breaking hard and brittle materials: concrete, brick, wood, natural stone, etc.
Many buyers confuse this device with an electric drill.
It is worth noting that rock drills use a completely different operating principle than impact drills.
In our article, we'll talk about how to choose a good rock drill, and also consider the rating of these popular electrical devices.
How to choose and what to look for?
When buying a tool, it is important to pay attention to the main technical parameters.:
- Impact energy determines the performance of the rock drill... The larger it is, the faster the chiselling process will take place. To operate the device at home, a tool with a maximum impact force of 2 J.
- Power must match the force of impact... For example, a power of 700-800 W is optimal for an impact energy of 2 J.
- Beats per minute... The higher the value of this parameter, the faster the hole will be drilled. A high value of the number of impacts (4000-8000 / min) helps tools with low power and impact force to have good performance.
- Chuck type... The most common ones are SDS-Max - for low power rock drills; and SDS-Plus for heavy-duty tools and shanks, 18 mm dia.
- Modes of operation... The chiseling function uses a reciprocating motion to drill shallow holes. Impact drilling is used when working with concrete and natural stone. The screwdriver mode will also be useful.
