Frequently Asked Questions

What are the advantages of using a DTH drill bit?

DTH bits offer high penetration rates, straighter holes, and are more efficient in hard rock formations compared to other drilling methods. They also ensure lower energy loss as the hammer is positioned directly behind the bit.

Is this 115mm bit compatible with standard hammers?

Yes, this 115mm bit is designed with a DHD340 shank, which is a standard interface for many high-pressure DTH hammers used globally.

What material is used for the cutting buttons?

We use high-quality YK05 or T6 tungsten carbide buttons, which provide excellent wear resistance and durability in various geological conditions.

How does the design reduce air consumption?

The inner structure is optimized based on advanced rock drilling theory to ensure maximum energy transfer to the rock, which naturally improves efficiency and reduces unnecessary air volume requirements.

What is the typical lifespan of these bits?

The lifespan depends on the rock hardness and air pressure, but thanks to the high-quality alloy steel and premium tungsten carbide, these bits are designed to provide a 15% to 30% faster penetration and longer service life.

Can these bits be used for water well drilling?

Absolutely. These DTH bits are ideal for water well drilling, mining exploration, and civil engineering due to their robust design and ability to handle high-pressure environments.
