What are the commonly used grades of hard alloy mining drill bits?

Commonly used grades of hard alloy mining drill bits include:

1.Tungsten Carbide: This is widely used due to its exceptional hardness and ability to maintain a sharp cutting edge under high-stress conditions. Tungsten carbide drill bits are suitable for drilling through the hardest materials, including rocks and metals.

2.Cobalt Alloys (M35 and M42): These cobalt drill bits are designed to handle extremely hard metals and are distinguished by their cobalt content. M35 contains 5% cobalt, while M42 contains 8% cobalt, making them highly durable and heat resistant.

3.Diamond-Tipped: These bits feature industrial-grade diamonds on the tips, providing unparalleled hardness and the ability to cut through the hardest materials, such as concrete and stone.
