Lb Well depth : To recover the chips produced during installation Insert length + 2 to 3 mm
The insert must be fully buried in the material :Insert length +1 mm
A larger hole will make it easier to fit the insert but at the expense of the holding force and torque resistance. Plan a counterbore and/or a chamfer to fit the insert more easily and ensure that it is flush with the surface of the material.
Depends on the material elasticity and the stress on the assembly.
