If holes have to be drilled in difficult substrates, the right tool is required. But what should the choice be – impact drill or hammer drill? Both variants have advantages and disadvantages.
areas of application
Holes can be drilled in different materials with both the rotary hammer and the impact drill. The difference is that screws can also be screwed in with a percussion drill – as long as the rotation speed is dosed appropriately and the impact is deactivated. This is not possible with a hammer drill. However, chiselling work can also be carried out with the hammer drill. For example, it is possible to use it to pry off tiles or to remove entire walls.
materials
Impact drills can drill through softer and harder materials. Wood, plasterboard and even concrete and metal can be processed with it. The rotary hammer is primarily suitable for hard materials. Care must therefore also be taken not to drill too fast or too hard on lighter subsoil.
effort
Impact drills have a mechanical impact mechanism. This means that the impact force is generated by gears and the impact frequency is very high. However, the impact force is comparatively low compared to a rotary hammer. As a result, a relatively large amount of force has to be applied when using the percussion drill. The effort required with a hammer drill is significantly lower because the hammer mechanism is driven electro-pneumatically. As a result, the device only has to be aligned and held in such a way that a clean drill hole is created or too much substance is removed when chiseling off.
volume
When using a percussion drill, it is always advisable to wear hearing protection. Due to the high impact frequency, an immense noise level develops. The rotary hammer is quieter due to its electric drive and the lower impact frequency and therefore less strain on the hearing. Here, too, it is advisable to wear appropriate protection to protect your hearing and thus prevent damage. With longer use or very hard materials, there is only a marginal value in this area Difference, which of course can also be attributed to the manufacturer and the production of the device can.
Price
The prices of rotary hammer and impact drill do not differ too much. In general, however, powerful rotary hammers are somewhat more expensive than impact drills Already with a power consumption of 650 watts it is perfectly sufficient for most tasks are.
Accesories
Impact drills are generally more versatile in use. For this reason, there are usually more accessories available for them in the form of bits and attachments.
In addition to the usual drill bits, there are also mortising bits or chisels for hammer drills. With these, for example, old tiles can be removed from the wall, but also natural stone and other hard materials can be removed.
recommendations
Due to the different properties, the impact drill and the rotary hammer prove themselves in different situations. Impact drills are all-rounders, but with harder materials it is necessary to use more force yourself. In addition, they cannot be used to chisel off tiles and the like, nor can they remove entire walls. That applies to the rotary hammer, however. However, a potential disadvantage is that the device cannot be used to screw in screws. However, if you already have a cordless screwdriver in your equipment and often have to work on hard materials, you should opt for a high-quality rotary hammer.
Tip:
Safety clothing and equipment should always be considered, regardless of the type of equipment chosen. Ear protection, a mask to protect against dust in the respiratory tract and goggles as a safeguard against flying particles, dust and other potentially harmful influences makes sense both when using a hammer drill and a percussion drill.
