100mm diameter unitised wheels, 3mm wide on a 6mm spindle
Grade 7 SA unitised abrasive wheels are flexible but have a much stronger than the grade 5 or 6 which increases the amount of cut the SA7 can achieve whilst leaving a 320 grit finish on the workpiece
Grade 7 unitised is flexible enough to get into the root of a tig weld and remove the ripples to leave a burr free, entrapement free finish
Use the SA7 also for heavier deburring of threads and thin cut edges.
