What to consider before buying

When choosing a boring bar, consider material (steel vs carbide) based on workpiece and cut depth. Carbide offers better wear and finish but is more brittle. For hobbyists, a steel set or single carbide bar is affordable. For production, indexable or solid carbide bars improve efficiency. Check shank size to fit your tool holder.
