  VERTICAL INTEGRATION & R&D

HOPRIO designs and manufactures brushless motors, controllers, and tools in‑house. With 265+ patents and 100+ R&D engineers, we control quality and innovation from motor to finished tool.
  HIGH EFFICIENCY & LOWER COSTS

HOPRIO brushless tools deliver 20‑35% higher work efficiency and 30‑40% savings on discs. Lower energy use, near‑zero maintenance, and longer lifespan reduce total ownership costs significantly.
  INTELLIGENT PROTECTION & SAFETY

HOPRIO tool features soft start, overload, over‑temperature, and power‑off protection. Capacitor‑free, sensorless design removes common failure points for safer, more reliable operation.
  LIGHTWEIGHT & DURABLE

Brushless motors allow HOPRIO tools to be lighter and more compact than brushed alternatives. With no carbon brushes to replace, they last 3‑5 times longer and reduce operator fatigue.

ADVANTAGES OF HOPRIO

We firmly believe AC brushless is a new trend in the world.
