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 100mm to 400mm.

Trepanning can be utilized in:

·        Machinery and Heavy Equipment

·        Manufacturing and Rebuild

·        Oil and Gas

·        Aerospace and Defense

·        metals Production and Distribution

·        Forging

Can be utilized when holes may be required in:

·        Finished Parts for Weight Reduction

·        Clearance

·        Fluid Flow

·        Working Cavities

·        Machining Blanks

·        Piston and Cylinder Features

·        Seals
