Extending the Life of Rock-Drilling Tools: Best Practices for TIGER Series

Durability and precision are the foundation of every TIGER rock-drilling tool manufactured by Set Makina. Yet even the most advanced tool can fail prematurely if it is misused or poorly maintained. Understanding correct handling, lubrication, and wear-control techniques ensures optimal performance and lower drilling costs.

1. Start with Proper Setup

Before drilling begins, the feed column must be firmly fixed to the rock surface. Any movement during impact causes bending stresses and early breakage. Modern TIGER drills include stable mounting stands for quick setup on steep or uneven terrain. Correct alignment between the drill, feed column, and bit ensures a straight hole and safer operation.

2. Maintain Correct Lubrication and Flushing

Always start the water supply before activating percussion and rotation. Dry running overheats the bit and damages the tungsten-carbide buttons. The water-flushing pressure should stay about 1 bar below air pressure to remove dust efficiently while preventing backflow into the hammer. Regularly replace worn seals and inspect rotation bushings to avoid internal wear.

Proper thread lubrication on rods and couplings prevents seizing and reduces fatigue. Use clean grease and keep containers sealed to prevent abrasive contamination.

3. Monitor Wear and Re-grind on Schedule

Continued drilling with worn bits increases energy use and shortens tool life. Each 150 m of drilling for integral bits — or 300 m for button bits — requires re-grinding. Tungsten-carbide buttons should be restored to their original shape using diamond-impregnated grinding wheels such as the Set Makina TIGER SET ROC IP. Periodic grinding maintains penetration rate and minimizes the risk of cracking.

4. Handle and Store Tools Properly

During transport, protect rods and bits from lateral impacts that can start micro-cracks leading to fatigue failure. Store them horizontally on cushioned surfaces and avoid contact between carbide tips. Use proper wrenches when removing bits — never a hammer — and inspect threads with gauges to identify wear before reuse.

5. Practical Benefits

Following these maintenance principles delivers measurable gains:

• up to 30 % longer tool life
• higher drilling speed and consistency
• fewer unplanned stoppages and lower total drilling cost

Conclusion

Proper care and maintenance of TIGER drilling tools are essential to achieving long-term performance in quarrying and mining. With systematic inspection, lubrication, and scheduled grinding, operators can rely on Set Makina tools to perform safely and efficiently under the toughest geological conditions.
