Difference Between SDS Plus and SDS Max

When it comes to drilling, there are a few different types of bits and drivers that you can use. In this blog post, we’re going to talk about the difference between SDS Plus and SDS Max. Both of these drills have their own unique benefits, so let’s take a closer look at each one.

What is SDS Plus?

SDS Plus is a standardized drill bit system for use with rotary impact hammers. It was developed by the German company Bosch in the 1980s and has become the industry standard for this type of drill bit. SDS Plus bits are characterized by their unique S-shaped shank, which allows them to fit securely into the chuck of an impact hammer. The SDS Plus system includes a wide range of drill bits crafted from different materials and designed for different applications. Whether you’re drilling into concrete, brick, or stone, there’s an SDS Plus bit that’s up to the task. Thanks to their versatility and durability, SDS Plus bits are an essential tool for any professional contractor.

What is SDS Max?

SDS Max is a type of hammer drill bit that is used for drilling into concrete and masonry. The SDS Max system consists of a drill bit with an SDS (Slotted Drive System) shank and an SDS Max chuck. The SDS Max system provides more torque than the standard SDS system, making it ideal for drilling large holes or demolition work. SDS Max bits are available in a variety of sizes and lengths, and they can be used with both rotary and percussion hammer drills. SDS Max bits are also compatible with SDS Plus chucks.

Difference Between SDS Plus and SDS Max

SDS Plus and SDS Max are two types of SDS or Rotary Hammer Drills. SDS Plus is the smaller of the two and is typically used for light-duty applications such as drilling into wood or soft metals. SDS Max, on the other hand, is larger and more powerful, making it ideal for heavy-duty applications such as concrete drilling. Both SDS Plus and SDS Max use a collet chuck to hold the drill bit in place, but SDS Max has a larger diameter chuck, meaning it can accommodate larger bits. In terms of power, SDS Max drills are typically more powerful than SDS Plus drills, but they are also heavier and more bulky, making them less maneuverable. When choosing between an SDS Plus and an SDS Max drill, it is important to consider the intended use and application. For light duty tasks, SDS Plus is usually sufficient, but for heavy-duty tasks, SDS Max is typically the better choice.


Bosch offers two types of SDS-plus drills, the standard SDS-plus and the extreme power SDS-max. The biggest difference between the two is that the SDS-max can handle more torque and has a longer life expectancy. If you’re looking for a drill that can handle some serious drilling, then you want to go with an SDS-max. However, if you don’t need all that power and are just looking for an everyday drill, the standard SDS-plus will do just fine.
