Diamond coring loads require big anchors. Maximum normal force (FN) on a core bit:
- High torque (MD) gear setting (low rpm)
- Small bit (r small)
- Blunting bit (µ = 2)
Anchor load (FA) is defined by FN and baseplate geometry. FN is the operator´s pressing force.
Coring applications are the most critical concerning anchor failure. High torque and small core bit diameter favor anchor pull-out.
