SDS vs SDS Plus: Understanding the Key Differences

SDS and SDS Plus are two types of shank systems used in hammer drilling with masonry drills. The SDS system was first introduced in 1975 by Bosch and is still widely used today. SDS Plus is a newer and improved version of the SDS system that was introduced in 1988. Both systems are designed to provide better hammer drilling performance than traditional chuck systems, but they have some important differences.

The main difference between SDS and SDS Plus is the size of the shank and the number of grooves. SDS Plus has a smaller shank diameter of 10mm and four grooves on the shank, while SDS has a larger shank diameter of 11mm and two grooves on the shank. The additional grooves on the SDS Plus shank provide a better grip and prevent the bit from slipping during hammer drilling. SDS Plus also provides better hammer drilling performance than SDS due to its improved design.

Understanding SDS Technology

As a professional in the construction industry, I have come across many types of drill bits and chisels. One of the most commonly used system is the SDS, which stands for “Slotted Drive System” or “Special Direct System”. In this section, I will explain the history and evolution of the SDS system, as well as the mechanism behind it.

History and Evolution

The SDS system was first developed by Bosch in 1975 and was later adopted by other manufacturers. The system was designed to provide a more efficient way of drilling into concrete and masonry. The original SDS system had a shank with two grooves on either side, which allowed the bit to be inserted into the chuck and locked in place with a spring-loaded ball bearing. This system was an improvement over the traditional chuck system, which required tightening of the chuck with a key.

Over time, the SDS system has evolved to become more efficient. The SDS Plus system, which was introduced in the 1980s, has four grooves on the shank instead of two, which provides a better grip and reduces slippage. The SDS Max system, which was introduced in the 1990s, has an even larger shank and is designed for heavy-duty drilling and chiseling.

SDS Mechanism Explained

The SDS system works by using a mechanism that allows the bit to move back and forth within the chuck. When the bit is inserted into the chuck, the grooves on the shank engage with the mechanism, which allows the bit to move freely. When pressure is applied to the bit, the mechanism locks the bit in place, which provides a more secure grip.

The SDS system also has a unique feature that allows the bit to be removed quickly and easily. To remove the bit, the user simply pulls back on the chuck sleeve, which releases the mechanism and allows the bit to be removed.

In conclusion, the SDS system is a highly efficient and reliable system for drilling into concrete and masonry. The system has evolved over time to become more efficient, and the SDS Plus and SDS Max systems are now the most commonly used types of SDS systems. The mechanism behind the SDS system is simple yet effective, and the system is easy to use and maintain.
