Product instruction:

Our impregnated diamond core bits are the most commonly useful bits in the mineral exploration

industry, as they have the widest range of application. The carefully selected grades of high quality

synthetic diamond are distributed in the depth of impregnated bit's matrix series. The matrix layer

of the "DIYFIA" contains a uniform distribution of these crystal that are embedded in a powdered

metal bond.

Introduction:

diamond drill bit has excellent ability in drilling concrete, reinforced concrete and brick wall.

segment and thinner tube wall can easily reduce the resistance and increase the drilling speed

(compare with the assembly type).

1.Thinner diamond segment and thinner tube wall can easily reduce the resistance and

increase the drilling speed (compare with the assembly type)2.provide 20% higher cutting performance, particularly in difficult operating conditions.3.Very fast cutting speed and low cutting pressure.4.Different connection end for different drilling machine.5.Especailly effective in drilling through reinfored concrete.
