Adjustments maybe necessary depending on machine rigidity, work material L geometry and clamping. Note 2) A carbide shank extension is recommended to prevent vibrations. NOTES ON MACHINING METHODS a How to choose an appropriate diameter tool. a Relation of the cutter diameter and corner R size of work material Machine plain surfaces with a larger tool and corner radii A guide for the smallest possible work material radius that with smaller diameter cutters. can be machined is from 0.6 ─0.7 x diameter of the tool.
