Product advantages：Tapered cartridge rolls are small size coated abrasives which are fixed on the steel axles. In addition to restoring cutting tools and dies efficiently they are also widely used for reaching into deep holes where larger diameter tools cannot, grinding edge breaking and irregular shape work pieces. These cartridge rolls are characterized by higher efficient, quickier heat—losing and unhurting workpieces, etc. They can be exchanged with all kinds of small size precision vitrified mounted wheels.
