Air Tools & Compressor Accessories
Handheld pneumatic rock drill
A light percussive drill with air flushing, for short holes in rock and concrete where a rig cannot reach. Used for anchor holes, secondary breaking and small-scale blasting rounds.
Features
- Percussion and rotation are both air-driven, so the machine has no electrical parts and works in wet and confined locations.
- Air flushing clears cuttings and cools the bit; without adequate flushing air the hole packs and the rod jams.
- Rod and bit are separate consumables with matched threads, and mixing thread systems wastes both.
- Practical hole depth is limited by rod length and flushing capacity, typically a few metres for handheld work.
- Air consumption is high for the tool size, so one drill can occupy a substantial share of a site compressor.
- A stand or air-leg version transfers the feed force off the operator and roughly doubles achievable penetration rate.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Air consumption | 1 800 - 3 500 | l/min | Often the largest single demand on a site compressor. |
| Working pressure | 6 - 7 | bar | Directly sets penetration rate. |
| Hole diameter range | 22 - 45 | mm | Fixes the bit and rod system. |
| Practical hole depth | 1.5 - 6.0 | m | Limited by rod length and flushing air. |
| Tool weight | 18 - 30 | kg | Decides whether an air-leg is needed. |
