A TNMG 16mm boring bar is typically:
- A solid steel shank tool holder designed to clamp a TNMG carbide insert.
- Made for internal turning (boring) operations on CNC lathes or manual lathes.
- Used to drill holes to precise diameters and achieve good surface finishes.
- Built to accept TNMG inserts (like TNMG160404, TNMG160408, etc.), which are triangular negativerake carbide inserts.
