Sinocoredrill Diamond Core Drill Bits HW Casing Shoes , High
Penetration Rate
Casing shoe is used on the leading edge of a casing tube string to
advance it through the overburden layer and into the bedrock by
means of rotational drilling. Depending on the range of
application, the cutting media on the core bit may take the form of
synthetic diamond, tungsten-carbide particles or tungsten-carbide
elements.

Notice :
To select the right bit for the job, assess the speed and power of
your drill for the size and depths of the holes to be drilled and
assess ground conditions such as rock type/formation and down-hole
conditions.
Size:
SINOCOREDRILL bits are available in all standard drilling sizes .
Also, non-standard sized bits can be produced according to
requirements from clients.
