Trepanning is a drilling process that leaves a core. Trepanning is a deep hole drilling process that has broad application over many industries. In many cases, trepanning is meant to be a roughing operation to be honed for finish, or machined further. In other cases, the trepanned hole is fit for use ‘as-drilled’.
The common factors for choosing trepanning are a long design, through bore, and within size ranges of 4.1″ to 15.75″.
