Guards and Flanges
It is important to choose the correct guards and flanges to use with
the grinder accessories. See page 50–51 and this page for the correct
accessories.
NOTE: Edge grinding and cutting can be performed with Type 27
wheels designed and specified for this purpose.
WARNING: Accessories must be rated for at least the speed recom-
mended on the tool warning label. Wheels and other accessories
running over rated accessory speed may burst and cause injury.
Every unthreaded accessory must have a 7/8" arbor hole. If it does
not, it may have been designed for a circular saw and should not be
used. Use only the accessories shown on pages 50–51. Accessory
ratings must be above listed minimum wheel speed as shown on tool
nameplate.
