NRQ series drill rods undergoes technical upgrading on the basis of Q drill rods. Well drilling capability is improved and well drilling cost is decreased due to its stable and reliable connection.
ZL Drilling Impregnated Drill Bits are made using special and patent formula with sophisticated powders for making sure premium quality and getting optimum drilling performance balance with longer service life. For making sure the user can choose the bits easy, through the hard working of our engineers, our impregnated drill bits can cover wider range of application, fewer bits types but for whole ranges of the rocks, so it can make you have a good experience for bits selection and reduce your inventory cost at the meanwhile.
Benefits of Impregnated Drill Bits
Durability with special matrix ( cuts hard rock faster with longevity).
Reinforced OD and ID gauges design, so you don’t worry about the gauges lose.
Drilling straighter than normal bits.
Better core samples recovery.
Different Crown and Grades of Our Impregnated Drill Bits
Junior Grade:11mm, Cost Effective
Suitable for soft to medium hard formation not broken too much , this is an economical choice. Most popular for Indian market.
Navigator Grade:14mm, Ideal Choice
Suitable for hard to very hard formation with good penetration speed and lifespan .Our best sellers to oversea market.
Master Grade: 15/16mm, Top Quality
Have a very good flexibility for various rock formations with our best quality, especially for compete rock formation with non- abrasive.
All of them have wonderful engineering and special designs, experts in powder metallurgy with sophisticated sintering and CNC machining, strict quality control and precise gauge protecting technology, all of those procedures are only for ensuring best work-life and good penetration rates, especially for MASTER bits, which are widely used in Mideast countries, Russia language speaking countries and South America for tackling tough rock conditions. Not only for impregnated drill bits, but also we provide surface-set diamond bits, PDC bits, T.C bits for your selection and we are capable of designing the bits according to our customers specified requirements.
