Superior Quality Diamond Segment for Drill Bit
Description:
This segment is made up of two parts:diamond working area and the welding layer which contains no diamond.
The characteristics of a single grain size of diamond and wide horizontal spacing can improve the sharpness of core bit, and ensure that the core bit is suitable for drilling reinforce concrete of different hardness degrees. In addition, the diamond longitudinal arrangement is interlaced, which can ensure the continuous diamond exposure and stable drilling. Besides,the welding layer contains no diamond, which can guarantee the welding strength and drilling safety of the core bits.
