1.Long working life 2.High penetration rate 3.High core recovery ratio 4.Verious sizes 5.Fast lead time
Characteristics:
YC impregnated diamond core drill bits are characterized by high efficiency and long life, work extraordinarily well for special strata such as hard, crisp, debris, slipping type of rocks and ferroconcrete. Drill bit standard: Q series, T series, nonferrous metal metallurgy standard and customer standard available. Full spec. Series of product can be provided. Electroplated drill bits are also available for better performance in engineering reconnaissance and ground processing.
Impregnated core bit description:

Electroplated diamond core bit description:
Model | Regular sizes | Suited stratum | International standard |
Single tube electroplated diamond core bit and reaming shell | Φ36,Φ46,Φ56,Φ75,Φ76,Φ91,Φ94,Φ110,Φ130,Φ150,Φ170,Φ200,Φ220,Φ275,Φ325 | 1. Drilling for the hardness and abrasiveness complete strata. 2. The strata of ractured congested the core of double tube bit. 3. The strata of above cases, the cores can not be flushed liquid erosion easily. 4. Drilling level holes and vertical holes in the trenches. 5. For sampling drilling. 6. Small diameter and shallow drilling in project. | AQ,BQ,BQ3,NQ,HQ PQ,PQ3 |
Double tube electroplated diamond core bit and reaming shell | Φ46,Φ56,Φ59,Φ66,Φ75,Φ76,Φ77,Φ91,Φ94,Φ110,Φ130 | 1. Used for drilling weak to moderate hard and hard strata of abrasiveness. Good at drilling "Slippage" strata. 2. The matrix has a high abrasion resistance, and also working good in slightly higher abrasiveness strata. | AQ,BQ,BQ3,NQ,HQ PQ,PQ3 |
