For
drilling blast-hole, ground hole and , etc., where taking a core sample is
not necessary, non coring bits are used. As the time spent to take and
remove the cores is eliminated , non core drilling is much faster.
Polmak
manufactures Non Core Diamond Bits for all required sizes with the
required connections.
