Matrix body fixed cutters are made from tungsten carbide material. This provides improved wear resistance and erosion.Additionally, they are typically more heavy set as far as cutter count.In applications of high fluid volume or high sand, matrix body PDC bits offer longer life and multiple bit runs.
PDC Drill Bits are equipped with Hardened Alloy Steel base material;High performance PDC-Cutters;Carbide and Diamond gauge protection;Carbide/Diamond Shock Studs;Threaded or Plain Carbide Nozzles for Flushing
Above features are subject to changes and modifications according to customers' requirements.
Matrix Body PDC Bit advantage :
2.Cutting structure is force balanced ,non-symmetrical blade and wide gage are designed so that the bit drills more stable and resulting longer working life of the bit
3.Better wear resistance and higher strength of the bit are guaranteed in regard to material and structure by using matrix body material with self-owned intellectual property rights and combining FEA analysis technology.
4.Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
5.CNC sintering process uses full automatic control. Inside and outside temperature of the bit is monitored during all procedures to fully embody material properties as well as ensure uniformity and stability of product quality.

Imported cylindrical roller bearings are mostly single-row; there are also double-row and four-row. Cylindrical roller bearings and raceways are imported bearings with line touch. The load can be large; the radial load is accepted first. The rolling body and the ferrule rib Conflict. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
According to the ferrule with or without ribs; divided into NU, NJ, NUP, N, NF and other single-row bearings; and NNU, NN-shaped double-row bearings. This type of imported bearings are separable layout of the inner ring and outer ring.
Cylindrical roller bearing without inner ring or outer ring; its inner ring and outer ring can move relative to the axial direction; therefore, it can be used as a free end bearing. There are double ribs on one side of the inner ring or outer ring. The other side of the ferrule has a single ribbed cylindrical roller bearing; can accept a certain degree of axial load in one direction.
Double row cylindrical roller bearing; high rigidity to radial load; first used for machine tool spindle.
Usually steel plate stamping cages; or copper alloy car cages. But some also use polyamide forming cages.
