The carbide button is sintered by coarse grained cemented carbide,
with proerties of high hardness and good transverse-rupture
strength, as well as corrosion resistance, resistance to acid and
alkali, long service life.
They are mainly classified as follows: the cutting tips used by
cold pavement milling-planing machine, the cutting tips used by
rotary digging machinery, the cutting tips used by coal digging
machine, the cutting tips used by roadway and tunnel boring
machine, the cutting tips used by trench excavator etc. They are
widely used for crushing or milling rocks. Cutting tips are tools
for rock digging widely used in mining and geotechnical
engineering.

〇 Second Selection Grade
Cemented carbide can be used for making the drill bits/ end-mills /
reamers; automobile special cutters, printed circuit board special
cutters, engine special cutters, horologe processing special
cutters, integral vertical milling cutter, graver and etc. Besides,
they can be also used for making of cemented carbide stamping head,
core bar and perforation tools.
