Norton 3X Super Cool 6"x3/4"x1" 120 Grit I-Grade Grinding Wheel #04681 Reviews
Controlled micro fracturing of the wheel grain of Norton 3X wheels provides a constant, sharp supply of patented SG (ceramic alumina) grain cutting points. This superior performance product has the highest wheel life, and combines an exceptionally fast cut rate with burn free grinding. 3X wheels are excellent for grinding plane blades, chisels, and turning tools on a bench or pedestal grinder. They handle all the hard, tough, and difficult to grind tool steels which are used for most premium plane blades, including A2. I-Grade and K-Grade Ratings - I-Grade Wheels: A bit softer, more friable, and run cooler. They are perfect for most general purpose grinding and sharpening. - K-Grade Wheels: Harder and less friable, and do not wear or groove as easily as the I-Grade. K-Grades tend to run a bit hotter than the I-Grades, but they are ideal for handling the very toughest tool steels. USA and Import NOTE: 6" grinding wheels come with bushings to fit 1/2", 5/8", 3/4", and 7/8" shafts. 8" wheels come with bushings to fit 5/8",3/4" and 7/8" shafts. The center arbor hole for both 6" and 8" wheels is 1" in diameter without the bushings installed. We find that Norton Wheels generally run much truer out of the box than other brands we have tried. However, as with any grinding wheel, be sure to dress them before use for smoothest operation and best cutting action.
