While both a hammer drill and an impact drill can drill through wood and metal, only a hammer drill can drill through concrete, tiles, and brick.Often, the power of a hammer drill will be expressed in a unit of measurement called a Joule. Due to the added power a hammer drill has, it is often the drill of choice for specific applications. Comparatively, an impact drill will pulse and apply extra impact to the drill head as it rotates.Generally speaking, a hammer drill will have much more power than an impact drill. However, it may seem simple to remember, a hammer drill hammers, while an impact drill applies added force through impact.The hammer drill will add extra power to the drill head through a knocking or hammering motion. Is a Hammer Drill the Same as an Impact Drill?Īlthough the two types of drills may sound similar, the truth is that a hammer drill and impact drill are very different and used for different applications. The thicker the concrete or the larger the project, the more time it will take you to drill through the material with a conventional drill.If you ever use a standard or regular wood drill bit, you will not have much luck, and the difficult and tough concrete will likely ruin the drill bit. The masonry bit will allow you to drill holes into the concrete using a standard drill.Keep in mind that using a masonry drill bit on a standard drill will be slow work, and it may take multiple masonry bits to get through the concrete or the brick. If you do not own a hammer drill, it is possible to use a masonry drill bit on a common impact drill or standard drill. It is a powerful drill that sends additional pulsating power to the drill head to allow you to drill through thick and tough material. Related Questions What Can I Use Instead of a Hammer Drill?Ī hammer drill is a specialty tool that is often used to drill through masonry, tile, and brick. Simply work to maintain and replace your Bosch hammer drill’s internal parts to get your tool back into working condition once more. When the piston cannot create a vacuum, it quickly loses power, which can prevent your hammer drill from hammering. Often, the thin o-ring that helps create a vacuum on the internal piston loses lubrication or degrades. Usually, with just thirty minutes of work, getting a hammer drill hammering once again is possible. Bosch sells replacement parts, as well as service kits, that allow a savvy homeowner to disassemble their Bosch hammer drill and troubleshoot the drill. The most likely causes for a Bosch hammer drill that is not hammering are a broken piston, a collapsed roller bearing, or an internal cylinder collapse. If a Bosch hammer drill is not hammering, the problem most likely is internal. Unfortunately, sometimes a hammer drill does not create the hammering motion either while drilling through a material or running idle. A hammer drill not only provides rotational movement to drill through materials successfully, but it also provides a directional, pulsing, or hammering motion, which can help give your drill additional power. A hammer drill is often viewed as a specialty tool outside the realm of a standard, traditional drill.
