Used. Great working condition.
The Delta 23-700 is a wet/dry grinder designed for tool sharpening, particularly knives and chisels. It features both a traditional dry-grinding wheel for initial shaping and a slow-speed wet-grinding wheel for fine work. The wet wheel, running at a slow 70 RPM, is ideal for refining edges and preventing overheating during sharpening.
Slow-Speed Wet Wheel:
The wet wheel operates at a very slow speed (70 RPM), which is crucial for preventing overheating of the blade during sharpening. This helps maintain the temper of the steel and avoids damaging the edge.
Tool Rest:
The tool rest on the wet wheel is designed for easy adjustment and has a large working surface. However, some users find it too large for very short chisels and note that it can flex during use.
Water Reservoir:
The wet wheel is submerged in a water reservoir in the base of the grinder. The water helps to cool the blade and prevent overheating while also acting as a lubricant for the grinding process.
Motor:
The grinder is powered by a 1/5 horsepower motor.
Safety:
It's recommended to lock the power switch in the "OFF" position when the grinder is not in use, especially when using the wet wheel, to prevent accidental activation.
Maintenance:
The owner's manual suggests keeping the water reservoir clean and removing the water after use to prevent mineral deposits from forming on the wheel.
