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.
A good design of reaming shell can increase the stability and reduce vibration during the drilling, through our engineers more than 20 years efforts, our reaming shells can always keep good contact with the circumference of the hole, we only choose the terrific material to ensure the quality and longer service life in the hole.
Wireline Coring System- Impregnated Diamond Bits Dimensions
Type | B-WL(BQ) | N-WL(NQ) | H-WL(HQ) | P-WL(PQ) |
O.D. of Bit | Φ59.5mm | Φ74.6mm | Φ95.6mm | Φ122mm |
I.D. of Bit | Φ36.5mm | Φ47.6mm | Φ63.5mm | Φ85mm |
O.D. of Reaming Shell | Φ60mm | Φ75.8mm | Φ96mm | Φ122.6mm |
Note: Customized gauges of the reaming shell are acceptable, contact with our sales representative for getting more supports.
Product Advantages
* Diamond Impregnated Pad
Enables the use of large synthetic diamonds greatly enhancing wear life and eliminating the need for specialty shells in diamond exploration.
* Diamond Ground
Outer diameter grinding pre-exposes the diamond and reduces variation in size improving stability and helping to produce the longest lasting reaming shell available.
* Heavy Duty
Available with an optional heavy duty blank to prevent undercutting in extremely broken conditions (standard on oversize versions).
* Dual Pad
Available in dual pad 10” configurations for straighter holes when deviation is a concern.
Note: Q is the trademark from BLY, here we quoted for helping customers to do a selection only.
