Reinforced Concrete Drilling

  • When a hammer drill bit gets stuck in concrete or masonry, the tool can start twisting and injure the operator
  • It requires different impact rate in drilling and chiseling, drilling works require high-frequency impacts converted from motor power for better efficiency and effectiveness.
  • Drilling works are sometimes performed in hot and humid conditions, which would require better cooling performance, in order to prevent the motor from overheating damage.
  • The safety clutch used in the rotary hammer has been subjected to 20,000 time lifetime testing. It will shut down rotation when the drill bit gets stuck in concrete, thus ensuring operator safety.
  • Our power tools feature 20%-30% better impact rate than usual DIY products thanks to improved specifications of their impact structure (crankshaft, ram, etc.)which grants much better efficiency compared to common machines with the same weight.
  • To make sure the motor’s working power meets the rating, we apply strict designing and testing standards, and have optimized motor cooling, which grants over 10℃ lower working temperature than common DIY devices in the same running condition.
