R28 Thread 41mm Button Bit for 30% Faster Drilling in Hard Rock Applications
The R28 41mm Thread Button Bit is a specialized tool designed for top hammer drilling operations, featuring high-efficiency rock breaking and strong adaptability. It is widely used in hard rock drilling scenarios such as mining and tunneling.
Core Performance Advantages
Efficient rock breaking and fast drilling speed:The ball teeth adopt a parabolic tooth design, creating concentrated point loads when in contact with the rock, enabling rapid crushing of hard rock. At the same time, the high hardness of the tungsten carbide ball teeth efficiently transfers the impact energy of the rock drill to the rock, reducing energy loss. Compared with ordinary drill bits, it can shorten the single-hole drilling time by more than 30%, significantly improving construction efficiency.
Stable and durable, low operating cost:The tungsten carbide ball teeth have strong wear resistance and impact resistance, and combined with the high-temperature inlay process, their service life is far higher than that of ordinary alloy drill bits. In addition, the R28 thread is reinforced, ensuring a tight connection with the drill rod and resisting high-frequency vibrations during rock drilling operations, reducing the frequency of drill bit replacement and maintenance, thereby controlling overall construction costs.
Wide compatibility and convenient installation:This drill bit is precisely compatible with R28 threaded rock drills from mainstream brands such as Atlas Copco and Sandvik, without the need for additional adapters. The threaded connection method makes installation and removal simple, reducing equipment downtime for drill bit changes and increasing equipment uptime.
