About This Product

Use the 415 dressing stone to clean the surface of the grinding stone and restore its original shape. You can also use the dressing stone to create a grinding stone with just the right shape for that special job. For best results, insert the accessory bit all the way into the tool and then back it out slightly before tightening down. This provides plenty of shank for the collect or chuck to hold onto the bit.

      Great little grinding stone. I used this on a flexible shaft to sharpen some old cutlery knives that I use outdoors on various projects. They did an excellent job putting a very sharp edge on the knives. I didn’t spend hardly any time sharpening the edges. The grinding stone cut cleanly and really didn’t produce the grinding dust that I was expecting. After I was finished I almost couldn’t tell which stone I had used, still looks in perfect shape. Very pleased with these.
