Quick Overview

SG-FLEX featuring ceramic oxide abrasive grain is recommended for fast weld removal and heavy deburring on all metals. 1/8" wheel thickness provides smooth grinding with minimal vibration for blending to a quality finish. Wheel flex during grinding process creates a large surface contact area for easy blending operations and reduced risk of gouging the workpiece material.

SG-FLEX wheels may be ordered with 5/8-11 Quick change hub. These allow for quick disc change-ups. Please note that the hub reduces disc flexibility , and creates a more aggressive grinding action with a rougher surface finish than the same wheel without hub.

For optimal flexibility and best performance, PFERD recommends SG-FLEX wheels be run with 7/8" arbor hole and backing pad.
