The CQS-3.5 Mining Handheld Percussion Drill is engineered for drilling operations in rock, brick walls, concrete, and similar materials. This versatile tool facilitates pipeline installation, power line erection, and anchor bolt placement across various environments including chemical plants, road construction sites, tunnels, sewers, and confined spaces. Its explosion-proof design ensures safe operation in gas-rich underground mines.

Compatible with standard five-hole drill bits commonly available in hardware stores, the CQS-3.5 offers convenient sourcing and cost-effective operation.

Ideal for drilling operations in refineries, construction sites, heavy industries, hazardous tunnels, underwater environments, and confined spaces. The pneumatic explosion-proof design eliminates spark generation, making it exceptionally safe for high-gas mining operations while improving work efficiency and reducing labor intensity.
