tools for drilling through rock in tunnels, specifically designed

However, integrating such a mechanism is not without its challenges. The ballistic button bit requires precise manufacturing to ensure safety and reliability. The launcher must withstand repeated use without failing and the projectiles must be designed to not pose a risk of injury or damage to the surroundings. Additionally, the cost of production for such a specialized component might limit its initial adoption.
