With more than 20 boring mills GBS always has a solution for your challenge
Boring is an operation to repair a hole in a metal object. The hole may be damaged, deformed or worn. Unlike turning, the object stands still and the tool moves.
This regular boring technic is used to make holes deeper while maintaining the same diameter.
The flattening technique is used to make holes larger in diameter by making the bit larger and larger circles and working to the correct size.
