7′′ 33mm Tapered Bits Taper Cross Drill Bit for Coal Mining

7'' 33mm Tapered Bits Taper Cross Drill Bit for Coal Mining

Taper cross bits can be used under any rock drilling condition because of it's comprehensive adaptability. Compared with taper chisel bits, taper cross bits have a better drilling performance because carbide tips on cross bits doubled, which means carbides shape are cross type on drill bits. Taper cross bit is mainly used for hard or very hard rock formation. 

The drilling depth is usually 15m-18m of hardness grade F8-14. 
 

Taper cross bit has excellent wear resistance, both in terms of durability and longevity. Its rugged construction has been specifically designed to withstand constant wear and tear, making it ideal for heavy-duty drilling applications. Superior wear resistance ensures that the bit is always in top condition, providing reliable and consistent performance over long periods of time.

Thanks to its high-speed drilling capabilities, Taper cross bits offer unmatched efficiency and productivity. Carefully designed to cut even the hardest materials with ease, ensuring fast and precise drilling and greatly reducing project completion time. Its optimized design enables rapid penetration and improved drilling performance, saving you valuable time and resources.

It is widely used in earth and stone engineering mining Wells drilling construction projects drilling Wells edge pillar support.
