The standard BG 121 is designed to be the most affordable blade grinder available.
All BG Grinders feature a totally enclosed standard duty motor which requires an arbor to mount the R.B.G. grinding wheel.
All BG and R.B.G grinders have a specially designed reversing switch which allows you to grind both right and left hand blades to a fine hollow grind.
All BG and R.B.G. grinders have a quick guard removal for easy wheel replacement.
