company news about Where is the DTH Bit Used?

1. Granite and hard rock:
Description: Granite and other hard rocks are dense and abrasive and require durable drill bits to drill efficiently.

Recommended DTH Hammer Drill Bits: The carbide balls or inserts on the drill bit are essential for drilling through hard rock. Tungsten carbide balls are common in down-the-hole hammer drill bits designed for granite and similar hard formations.

2. Limestone:
Description: Limestone formations vary in hardness, but they can be abrasive and may contain soft and hard layers.

Recommended down-the-hole hammer drill bits: Drills with tungsten carbide teeth are suitable. Depending on the specific limestone hardness, the balance between hardness and toughness of the carbide ball teeth is critical.

3. Sandstone:
Description: Sandstone is generally softer than granite, but can still be abrasive, especially if it contains quartz grains.

Recommended DTH Hammer Drill Bits: Drill bits with harder carbide teeth are necessary to withstand wear. Sandstone formations containing quartz may require drill bits designed specifically for abrasive materials.

4. Shale and clay:
Description: Shale and clay formations are relatively soft and prone to collapse during drilling.

Recommended down-the-hole hammers and drill bits for mining: Drill bits with round buttons or ball buttons are suitable for softer formations. These drill bits deliver good impact without causing excessive damage to the formation.

5. Coal:
Description: Coal seams are generally soft and non-abrasive.

Recommended down-the-hole hammers and drill bits for mining: Drill bits with ball buttons or flat designs are often used in coal seams. These drill bits provide good penetration without creating excessive dust.

6. Mixed formation:
Description: Many mining sites contain mixed rock formations, with different rock types encountered during a drilling operation.

Recommended DTH Hammer Bits: Combination bits with different button types or designs strategically placed on the bit face for effective treatment of mixed formations. These drill bits are designed to handle the different rock types encountered during drilling.
