  • Single body design - More reliability and easier to service.  This solid housing eliminates leakeages and increases the lifetime of the cylinder.  You can (dis)assemble the SRD easily, so service becomes a breeze.
  • Assisted Flushing Technology - Uninterruped drilling and 17% more productivity.  Turn the flashing valve open to active the SRD's Assisted Flushing Technology.  This allows an additional flow of compressed air through a pathway in the cylinder, flushing the drill hole without interrupting operations.
  • Ergonomic handles - 50% lower hand and arm vibrations.  Lower vibrations mean more comfort and you can work longer with your drill.  An SRD drill has a vibration level that is 50% lower than that of a comparable RH rock drill of the previous generation.
  • Improved silencer - Noise redutions with 2dB may not seem a lot, but it makes a lot of difference, especially if you run more than one drill at the same time.
  • Quick tool changes - kick-latch retainers allow you to quickly and easily swap tools.
  • Comfortable drilling - built-in silencers, a lightweight design and vibration reducers ensure safe and comfortable operations.  Thanks to HAPS (Hand and Arm Vibration Protection System), vibrations are reduced up to 75%.
  • Balanced performance - these surface rock drills are designed for excellent balance, without adding unnecessary weight.
