HMLC NMLC Impregnated Diamond Core Drill Bits For Soft Hard Rock

?

?

Description:

?

Our company& acute;s performance of IMP.bit is determinded by combination of diamond and matrix, Jinshi uses special matrix and provide optimal performance:
matrix have 5 different crown height: 9mm,12mm,14mm, 16mm, 25mm

?

?

Our impregnated bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.
