casing drilling CwD

[@epistte]

How is a drill bit changed when drilling while casing?

[@deactivee-mail1005]

After the section has been drilled successfully, the bit is milled away.

The name itself says drillable bits. Once the casing has been placed then the smaller casing drillable bit will be milled through it
