                                                Application Medium-hard to hard formations with low
compressive strength , such as hard shale,
limestone, sandstone, dolomite, hard gypsum,
marble, etc.
                                                  Features The M137 is a matrix body PDC bit with 7
curved blade with back-reaming and spiral
gauge protection. Optimized Hydraulie design
and enhanced cleaing and cooling effects of
the bits to prevent bit from balling

 

Regular sizes of PDC cutters are 8mm, 13mm, 16mm, 19mm.

 

Regular blades quantities of PDC bits range from 3 to 9.

 

The smaller PDC cutters the harder rocks it can drill, the more blades quantity the harder it can drill. But penetration rate will be slower down after adopting smaller cutters and more blades, so choosing the best configuration of PDC bits is very important before starting projects.

 

Drillers should consider:

 

1> Matrix body or steel body.

 

2> Cutter sizes and blades quantity.

 

3> Double rows cutters or single row.

 

4> Spiral or normal gauge protection, gauge length, gauge protection materials.

 

5> Nozzles.
