This grinding wheel may have small chips and there will be a mark on the side where we have removed material to balance the wheel. These are imperfect but NEW grinding wheels (or very lightly used), 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.
