Wall Slotting

  • Drilling and chiseling requires different impact capacity performance compared to simple drilling jobs. Chiseling work requires most motor power converted into impact power to achieve better demolition efficiency.
  • Wall chiseling produces powder of which granules are very tiny, which can easily invade device switches and oil seals, causing switch malfunction and oil leakage.
  • The cylinder and chuck can be easily damaged in wall chiseling. Since they are required to bear massive impact force and vibration as their linking parts can be easily damaged.
  • Our chiseling equipment features 10%-50% greater impact capacity performance than common DIY equipment, due to ram weight and cylinder diameter parameter optimization. This leads to greater working efficiency.
  • Professional dust proof method is applied on switches, motors and oil circuits, leak proof and lubrication are both considered in grease selecting, to prevent from damage in dusty environments for extended periods of use.
  • Essential parts of our products apply 35CrMo alloy steel, processed with automobile industrial standard heat treatment equipment imported from South Korea, all treatment procedures are automatically inspected and controlled, to ensure professional level durability.
