❓ Frequently Asked Questions
What are the main differences between the BR series and DHD30R hammers?
The BR series (BR2, BR3) is designed for specific pressure ranges and threads like RD50, while the DHD30R supports a higher working pressure range (up to 25 bar) and uses an API 2 3/8" REG PIN connection.
What air pressure is required for optimal performance?
Recommended air pressure varies by model: BR2 requires 8-15 bar, BR3 requires 10-17 bar, and DHD30R operates best between 10-25 bar.
Can these hammers be used for water well drilling?
Yes, these DTH (Down-The-Hole) hammers are suitable for various applications including water well drilling, mining, and construction.
What is the recommended rotary speed for these tools?
For the BR2 and BR3 models, 30-50 r/min is recommended. The DHD30R can handle a slightly higher range of 30-60 r/min.
Are the drill bits included with the hammer?
The specifications provided are for the hammers alone (weight and length without bits). Drill bits are typically selected separately based on the rock formation.
How do I maintain the DTH hammer for a longer lifespan?
Proper lubrication, maintaining the correct air pressure, and regular inspection of internal components are key to ensuring durability and performance.
