High Drilling Rate Diamond Core Bit For Coal Mine With A Latching
Mechanism
Specifications:
NW Casing Shoe
1. Simple configuration
2. Easy installation
3. Affordable prices
Casing Shoe Bit
The inside diameter of the casing shoe bit is not set with diamonds
sometimes(surface set Type) and flush with the inside diameter of
the casing. Basically,the corresponding size of Drill Bits and Core
Barrels have to get through the inner diameter of the casing shoe
bits freely.
Casing Bit
The inside diameter of the Casing Bits are set with diamonds and is
smaller than the Casing Shoe Bits. It will not permit the passage
of the core barrel.
Rod Shoe Bit
We also make the Rods Shoe Bits to use with the Wireline Drill
Rods.
PDC Drill Bit For Sandstone Drilling
1. New Superhard Material;
2. High Drilling Rate;
3. Wearable Blade;
4. Used For Coal Mine
1. Cutting toos adopts superhard material, long service life drill
bit;
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
