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

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
