Power and Impact Energy:

1. SDS Plus tools typically deliver impact energy that is sufficient for lighter-duty tasks some heavy-duty. They’re perfect when precision and ease of use are more important than raw power.

2. SDS Max tools, on the other hand, can deliver advanced impact energy because they have longer lengths. This makes them the go-to choice for heavy-duty demolition and deep drilling.

Bit Size and Capacity:

1. SDS Plus bits generally range from 5/32 inch to 1 inch in diameter. This is more than enough for most residential and light commercial tasks.

2. SDS Max bits, however, can range from 3/8 inch to over 2 inches. If you’re dealing with thick concrete or stone, the larger capacity of SDS Max is essential.

Shank Design:

1. SDS Plus shanks are smaller, which makes bit changes quick and easy. They’re designed for versatility and ease of use.

2. SDS Max shanks are larger and more robust, designed to handle the increased power and torque of heavy-duty work.

Tool Compatibility:

1. SDS Plus tools are generally smaller and lighter, making them easier to handle, especially in tight spaces or when working in overhead scenarios.

2. SDS Max tools tend to be larger and heavier, which requires more power to operate but offers far greater impact energy and drilling capacity.

Weight and Ergonomics:

1. SDS Plus tools are often more lightweight, making them easier to control and less fatiguing to use over long periods, especially on your hands or shoulders. They’re ideal for jobs where precision and ease of handling are needed.

2. SDS Max tools, while powerful, are also heavier and can be tiring to use for extended periods of time. They’re better suited for jobs where power is more important in the long run.
