The Multitool 2 x 36 belt grinding attachment for your bench grinder is a must-have tool for any fabricator! This versatile tool removes material up to 5 times faster than with the equivalent grit grinding wheel. Belts change in seconds from grinding, to sand deburr or polish. A variety of belts and discs are available for any project. Multitool fits most popular brands of grinders with screw-on type wheel guards with no special adapter required. We recommend at least a quality 1/2 hp grinder. Shaft size must be 1/2 inch or 5/8 inch. With a standard 3,450 RPM grinder belt speed is approximately 5,400 surface feet per minute. The fitting kit contains a universal adapter with radial slots to suit grinder's wheel guard mounting holes, and easy to follow instructions. Multitool will NOT fit a grinder with heavy cast wheel guards if the guards are used to retain the spindle bearings.
