PROCEDURE FOR SELECTING RIPPER POINT
PROCEDURE FOR SELECTING RIPPER POINT
REMARK
A symmetrical ripper point is suited to a terrain of hard rocks because it recovers penetrability by turning the point
after the penetrability drops due to its worn tip.
Ripper points usually lose their hardness when they undergo intense heat generated by a contact with rocks
during the use. In this respect, red ripper points are suited to a terrain of hard rocks where those others are likely
to slip during the use, because red ones are made of materials whose hardness less lowers under intense heat,
compared with yellow ripper points.
Where an amount of wear on a ripper point is limited, a heat- originated (thermal) crack on the point surface is
not readily removed, and the point itself can break with the crack as a starting point. For this reason, ripper points
for limestone (A) are suited to a jobsite where they are comparatively free of wear.
