Product Overview:
Our brushless square sander, equipped with a 550W brushless motor and a 21V lithium-ion battery, combines powerful performance, portability, and a user-centric design to meet the needs of contractors, woodworkers, and DIY enthusiasts.

Core Technical Specifications
This square sander is driven by a high-torque 550W brushless motor with an adjustable idle speed between 10,000 and 12,000 rpm, allowing users to fine-tune the sanding intensity for different materials and tasks. The 110×100mm square sanding base provides a wide, flat contact surface, ideal for quickly covering large surfaces while maintaining edge precision – perfect for flat surfaces, trim strips, and furniture components.
Key Advantages and User-Centric Design
This sander utilizes advanced shock absorption technology to reduce hand fatigue and numbness during prolonged use, ensuring stable operation and consistent sanding results. The compact, ergonomic body features a textured, non-slip grip that naturally conforms to the hand.

Highly Efficient Dust Collection and Heat Dissipation
Equipped with a rear-mounted dust bag and a labyrinthine air intake/exhaust system, this sander effectively collects up to 90% of airborne dust and debris, keeping the work area clean and reducing exposure to harmful particles. The dust bag is easily removable and reusable, simplifying maintenance and cleaning. Furthermore, the efficient heat dissipation design prevents the motor from overheating during continuous heavy-load use, protecting the machine from burnout and extending its lifespan.

Durable Brushless Motor
Compared to traditional brushed motors, brushless motor technology offers higher efficiency and durability, lower maintenance requirements, and a longer lifespan.
