Sharpening tool edges with a high-speed dry grinder risks overheating the steel and ruining its temper. That won't happen with this Variable-Speed Wet Sharpener. Its 220-grit aluminum oxide grinding wheel is constantly bathed in a water reservoir to keep its surface cool, and the motor spins it at just 90 to 160 RPM. A universal tool support, grinding jig and angle guide are included to help set and maintain consistent grinding angles. After initial sharpening, use the leather wheel charged with honing compound to strop away any burrs and polish your tool edges to a mirror finish.
Drilling, sawing, sanding or machining wood products can expose you to wood dust, a substance known to the State of California to cause cancer. Avoid inhaling wood dust or use a dust mask or other safeguards for personal protection. For more information go to www.P65Warnings.ca.gov/wood
