and buttons of rotary-­percussive bits, heavy rock

drill bits to cut hard and very hard formations.

It is mainly used for making cemented carbide

substrate tips to be used in PDC cutters for

excavating coal and oil field PDC bits.

Mainly for the stamping dies used in the

conditions of heavy impact load and large strees.
