SDS Plus and SDS Max are two different connection systems for electric drills.
The main differences lie in the design specifications and application scenarios:
Specification differences
SDS Plus: Square handle drill bit, handle diameter 10mm, featuring two grooves and two slots design, suitable for small to medium-sized hole drilling operations.
SDS Max: Five-notch handle design, handle diameter 18mm, featuring a three-slot two-notch structure, specifically optimized for large-diameter and deep-hole operations, with greater torque.
Applicable scenarios
SDS Plus: Suitable for conventional drilling of heavy materials such as concrete and stones. It is easy to operate and has a low cost.
SDS Max: Designed for large-diameter drill bits (such as those over 50mm) or deep-hole operations, it can withstand higher torque loads and prevent handle breakage issues.
Performance Features
SDS Plus: Pneumatic sliding design, enabling quick installation and efficient force transmission, but may experience insufficient torque during large-hole operations.
SDS Max: By increasing the diameter of the handle and optimizing the slot structure, it significantly enhances the efficiency of torque transmission, making it suitable for continuous high-intensity operations.
