Hammer drill or punch?
Already in the first stage of tool selection, confusion arises between the perforator and the impact drill. Despite the similar purpose of the tool, the main focus of the impact drill is drilling, the blow it has is very weak. Unlike the drill, the perforator has a strong impact due to the internal shock piston, it is specially designed for solid materials, it can withstand high long-term loads, and is resistant to building dust. Thus, the separation is obtained: if you need to make a small hole in the tree, drywall, foam concrete — you will fit a hammer drill; if you need to drill a wall for laying the Internet cable, air conditioning, mounting anchors, etc. — Take a punch.
The rotary hammer is an indispensable device that has entered the daily life of people, both in Ukraine and around the world. But what is it? A puncher is a power tool that allows you to make holes in hard materials (brick, concrete, stone). The work is carried out according to the principle of material punching due to rotation and translational blows by a special nozzle — a drill.
Everything related to making deep holes and working with durable materials is a task for a punch. Perforators are light and heavy, they differ in power, impact force, maximum drilling diameter, number of operating modes, manufacturer’s company and price. Even now, for example, in Kiev you can find two almost identical devices at a completely different price. We will try to figure out what makes this power tool different from its “next of kin” and analogs?
