This grinding wheel is un-used but may have small chips and will have a mark on the side where we have removed material to balance the wheel. These are imperfect but NEW grinding wheels, they have been "ring tested" and balanced - we are selling them at a discount because of their imperfections.
While supplies last.
The 9000-34 is the hardest wheel we offer as a one inch wide wheel. If you are looking for the longest possible life this wheel will provide that. The disadvantage of a harder grinding wheel is that your grinding time will take longer because this wheel does not break down as quickly to relieve the heat - you cannot push as aggressively into this wheel without beginning to burn the blade. This results in a longer sharpening time to manage the heat of the harder longer lasting wheel. While the 9000-34 is the hardest wheel we offer, it is still much softer than a bench grinder wheel or other competing lawn mower blade sharpeners which burn mower blades almost instantly.
