[Features] ●Because of the center cut, the grinding power is strong and the sharpness is excellent. ●Prevents surface sagging and provides smooth verticality. ●Higher hardness than zirconia abrasive grains and superior toughness compared to alumina abrasive grains, resulting in high grinding power and long life. ●Compared to offset whetstones, it is quieter, has better grinding power, and leaves a cleaner polished surface. ●The center cut is suitable for pinpoint strong grinding. ●I arranged trapezoidal paper and strengthened the tightness.
