Product Description

Far Eastern Drilling are API (API-7-1 & API Spec Q1) factory specializes in drill bits, such as Tricone Bit,PDC Bit,Hybrid Bit,HDD Hole Opener,Foundation Roller Cone Bits and related drilling tools,application fields include large-scale open-pit mining, such as open-pit coal mines, iron mines,copper mines and molybdenum mines, also the non-metallic mines.With the increasing in variety of type,it is also widely used in quarrying ,foundation clearing, hydrogeological drilling,coring, tunneling in raillway transportation department and shaft drilling in undergound mines.

Conical tricone rock drilling bits offer numerous advantages in quarry, pit, ore, and mine well operations:
 

1. Superior rock - breaking ability: The conical shape of the bit and the interaction of the three cones enable it to apply high - concentrated pressure on the rock surface. This allows for efficient penetration and fragmentation of rocks, even in extremely hard and abrasive geological formations commonly found in quarries, pits, and mines.
2. High drilling efficiency: With their efficient rock - breaking mechanism, conical tricone bits can achieve high drilling speeds. They can quickly bore through rock layers, reducing the time required for each drilling cycle and increasing overall productivity. This is particularly beneficial in large - scale mining operations where time is a crucial factor.
3. Excellent adaptability: These bits are designed to handle a wide variety of rock types and conditions. Whether it's hard granite in a quarry, dense ore - bearing rock in a mine, or tough shale in a pit, conical tricone bits can be configured with different tooth profiles and cutting structures to optimize performance. This adaptability minimizes the need for frequent bit changes, saving both time and money.
4. Even wear and extended lifespan: The tricone design ensures that the drilling forces are evenly distributed across the bit. This results in uniform wear of the cutting elements, prolonging the bit's service life. A longer - lasting bit means fewer interruptions for bit replacements, leading to increased operational efficiency and reduced maintenance costs.

5.Effective cuttings removal: As the bit rotates during drilling, the conical shape helps to efficiently displace and remove rock cuttings. The cuttings are directed away from the drilling face and into the wellbore, preventing them from accumulating and causing blockages or interfering with the drilling process. This keeps the drilling area clean and ensures the bit operates at peak efficiency.

6. Stable drilling and high - quality boreholes: The balanced design of conical tricone bits provides excellent stability during drilling. This allows for more accurate and straight boreholes, which is essential for various mining operations such as blasting in quarries, ore extraction in mines, and well - construction in pits. High - quality boreholes improve the effectiveness of subsequent operations and reduce the risk of borehole collapse.

7. Cost - effective in the long run: Despite their relatively high initial cost, conical tricone bits offer significant long - term cost savings. Their high efficiency, extended lifespan, and reduced downtime due to fewer bit changes result in lower overall drilling costs per meter of borehole. This makes them a cost - effective choice for large - scale quarry, pit, and mine operations.
