                                                  Features The M1375 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.

 Polycrystalline diamond compact (PDC) bits deliver premium performance and durability for a wide range of standard drilling applications. These matrix- and steel-bodied bits incorporate the latest cutter technology, computational fluid dynamics (CFD), enhanced hydraulics, and various structure geometries to maximize ROP.

**Matrix-body bit
Matrix-body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail. For diamond-impregnated bits, only matrix-body construction can be used.
** Steel-body bits
The strength and ductility of steel give steel-bit bodies high resistance to impact loading. Steel bodies are considerably stronger than matrix bodies.A beneficial feature of steel bits is that they can easily be rebuilt a number of times because worn or damaged cutters can be replaced rather easily. This is a particular advantage for operators in low-cost drilling environments.

Rock hardness and bit selection 
Cone bit IADC code  PDC  Formation  Rock Types  Compressive strength (Mpa) ROP(m/h)
111/124 M/S112~M/S223 Very soft: low viscosity, low compressive strength.
