The harder the material is, the more force you’ll need. As such, it’s better suited to drilling holes in softer materials.Īn impact drill’s mechanism only engages when you apply force with the drill against a material. Compared to the rotary hammer drill, the mechanical percussion mechanism of an impact drill is weaker but more precise. Two sets of toothed gear discs interact with each other, creating a horizontal back-and-forth movement of the drill bit and chuck. Although the impact frequency is lower than that of an impact drill, a rotary hammer’s force is much greater due to the stroke-like hammering method.Īn impact drill also uses a percussion mechanism, but the energy is generated purely mechanically. The percussion mechanism is coarser than that of an impact drill and smashes the material in a stroke-like movement. With a rotary hammer - as the name indicates - the drill bit rotates while a percussion mechanism provides a hammering effect. In addition to how they work, the two types of tools differ in what they are suitable for and how much physical effort you have to put in. The Bosch Electronic Speed Control, an additional variable speed control system, is available for work on specific materials. Some rotary hammer drills even have a 2-speed gearbox to provide optimum control over speed and torque. Also, you’ll want to consider whether to buy a corded hammer drill or not. These include whether the tool has the ability to reverse the rotation direction (for unscrewing screws, for instance), and whether it can utilise the Bosch Vario-Lock for more liberal chiselling applications (as the chisel must not rotate when in use). In addition to these fundamentals, there are other factors that can improve the effectiveness of rotary hammers. A Bosch SDS hammer drill not only guarantees optimum power transmission, it also enables drill accessories to be changed quickly and without additional tools .
