What are DTH Bits?

DTH bits are specialized drill bits designed to work with DTH (Down-The-Hole) hammers. They feature unique designs that optimize energy transfer from the hammer to the rock, resulting in efficient drilling performance.

Key Features of DTH Bits

• Thread Connection: Designed to match specific hammer thread types
• Carbide Buttons: Tungsten carbide inserts for cutting and breaking rock
• Flushing Holes: Channels for compressed air to remove cuttings
• Face Design: Optimized for different rock conditions
• Gauge Protection: Extra carbide to protect the bit diameter

DTH Bit Sizes

DTH bits are sized to match corresponding hammer sizes:

Hammer Size	Bit Diameter Range	Common Applications
3"	85-100mm	Blast hole drilling, exploration
4"	105-130mm	Mining, quarrying
5"	135-155mm	Large blast holes, water wells
6"	152-203mm	Mining, construction
8"	195-254mm	Large diameter drilling

Button Configurations

DTH bits feature various button arrangements:

• Standard: Balanced button placement for general drilling
• Drop Center: Aggressive cutting for high penetration
• Concave: For soft to medium rock formations

Maintenance and Care

To maximize DTH bit life:

• Monitor button wear and regrind when necessary
• Check thread condition regularly
• Ensure proper hammer-bit compatibility
• Maintain adequate air pressure for flushing
