This set includes three extension rods measuring 3 inches, 3.9 inches, and 5.5 inches, enabling customizable lengths for specific tasks.
On the other hand, the AVID POWER Angle Grinder is designed for cutting, grinding, and polishing across multiple materials. With a powerful 7.5-amp motor that delivers up to 12,000 RPM, this grinder is suitable for various applications including rust removal, metal cutting, and even masonry tasks. Its versatility makes it more functional for users who require a dedicated tool rather than just an accessory.
Build Quality and Durability

This ensures durability and longevity, particularly when working in challenging conditions. Its seamless docking feature ensures stable installation without loosening during operation.
Conversely, the AVID POWER Angle Grinder is also built with durability in mind, featuring a robust motor and an adjustable safety guard for protection during use. The inclusion of extra carbon brushes is a notable advantage, as they extend the motor's running time.
