Quick Guide to Picking Small Boring Tools

Check where you’re machining the inner hole and pick a suitable precision boring cutter shape — that’ll make the result spot-on.
Small boring tools come in different coating colors depending on the workpiece material. They’re all tuned up specially, so machining goes way smoother.
All the shapes in the diagram are left-cut (L). If you need right-cut (marked R), just switch L to R and reverse the direction too — easy enough!
