Want to make your down-the-hole drilling fast and stable? This guide is a must-have!

Before operation, thoroughly inspect mechanical, hydraulic, power, and electrical systems, ensure sharp drill bits and a functioning air compressor. Precisely position the drill, securing it horizontally and vertically to prevent (swaying).

During drilling, control drilling speed, adjust air pressure based on rock hardness, switch between dry and wet drilling as needed, and remove slag promptly.

Remember the “slow first, fast later; light first, heavy later” principle, keep the drill rod vertical, and avoid overloading and stuck rods.

Safety first: Wear protective gear, stay away from overhead power lines, and stand in safe areas.

Master these skills, and your drilling efficiency and quality will improve significantly!
