The most common types of drills that are used in rotary hammers are SDS Plus and SDS Max.
As compared to a hammer drill, a rotary hammer has a more powerful punch and can drill almost everything. To enable the drilling, the SDS Plus and SDS Max are usually installed in the hammer drill. These two drills are made to handle different construction and demolition projects such as concrete drilling or breaking concrete.
SDS Max vs. SDS Plus
When drilling concrete, the SDS Plus and SDS Max are the most commonly used bits. These two bits can be used in the same tool. When performing heavy concrete drilling, you should consider the SDS Max, as it will enable you to choose from a wide range of accessories. SDS plus bits are usually thinner and smaller as compared to the SDS Max Counterpart.
One of the major differences between SDS Max and SDS Plus tools is the size. SDS Plus are usually smaller and thinner as compared to the SDS Maxi bits. The thinner SDS plus is a good choice for light-duty tasks such as drilling holes. On the other hand, SDS Max is good for heavier duty jobs like drilling bigger holes.
SDS max with the SDS plus tools can handle one, two, or three capabilities…
For instance, a rotary hammer can combine the hammering with rotation. Some tools only have the drill only mode. These tools will rotate to drill through materials. Other tools combine the hammering action with drilling. These are a good choice for hammering through the tough materials that cannot be handled by the rotation drills only. Other tools have a demolition mode or chip-only mode.
SDS Plus has 4 large grooves (two of which are open and two are closed) and there are locking balls connected to the gloves. This means that it’s possible to interchange SDS plus with the older SDS. SDS plus can drill a hole with a diameter of 1 and 1/8 inches. This has a length of 10 mm installed 40 mm into a chuck.
SDS Max is commonly used in the bigger hammer drills that can drill holes with bigger diameters than what the SDS and the SDS Plus can drill. The SDS Max can also work like a chisel and is, therefore, a good choice for heavy-duty tasks such as chiseling, chipping, digging, and cutting. The drill has 3 open grooves and a feature for locking balls. It has a shank of 18mm and is installed 90mm into the chuck.
Application of a hammer drill
A hammer drill works like a normal power drill, producing a rotational motion. However, it also has a built-in hammer feature that enables it to deliver heavy hammering punches. This makes it a good choice for drilling through hard materials such as wood, stone, or brick. If you need a setup where the normal power drill isn’t working, you will need a hammer drill.
Whether you are a homeowner, a DIY enthusiast, or a professional who is looking to drill holes with a small diameter, then a hammer drill may serve you well. Remember that a hammer drill uses the traditional bits and chucks. This means that you need to tighten down the bit. Among the benefits of the SDS plus and the SDS Max bits is that both can stay well installed into a chuck.
Application of a jackhammer
At times, an SDS Max may not have enough punch to break concrete, patio, stairs, or other structures that are built from the thick concrete slabs. This is when you may want to use the jackhammer. Jackhammers have hex bits of 1 1/8” that are specially built to handle the tough masonry tasks that may prove challenging with the less durable and less powerful power tools.
The top-rated jackhammers are made in a way that enables them to power through even the high PSI concrete. If you are handling a concrete of less than 6″, a jackhammer will handle it easily. However, the strength and power of the jackhammer may have some cons. Jackhammers are a bit expensive, harder to transport, and aren’t the best choice for surgical work. This means they aren’t the right choice for working on delicate surfaces.
Conclusion for SDS Plus vs. SDS Max
Both the SDS Max SDS Plus and the SDS plus tool are made to make your masonry work easier. If you are considering buying an SDS Max or SDS plus tool, a jackhammer, or a hammer drill, ensure that you pick the right tool for the task. You would rather be over-equipped than under-equipped. For instance, a demolition task that would take half an hour when using the SDS max tool may take less than 10 minutes when using the jackhammer.
Therefore, if you find tht you are spending more time on your masonry project, you may want to consider more powerful equipment.
