2 Flute With Ball Bearing Guide
Not guaranteed due to extreme diameter and radius. For best results it is recommended to use a smaller radius bit or chamfer the material prior to using these large radius tools. Tool life will be prolonged and a smoother finish will result.
Replacement bearings #'s 49120, 49121 & 49122 use #47706.
All others tools use #47704 bearing.
Warning: Maximum RPM12! = 12,000; 18! = 18,000
