2. Can be greatly improved the in hard and medium-hard drilling efficiency;
3. Wearable blade, without grinding, convenient to use;
4. Reduce the labor intensity,it is suitable for lithologic strata at level 4-12
This type of bit uses seismic grade tungsten-carbide as the cutting media. Tungsten-carbide does not possess the hardness of diamond and as such has a limited range of application as a core drilling cutting media. Tungsten-carbide bits are however a very cost effective means of drilling softer unconsolidated formations.
Features :
1. High Penetration Rate
2. High Rotation Speed
3. High Performance
4. Long life drilling
5. High strong resistance to abrasion
