The diamond abrasive on this Edenta superflex cut-off wheel is sintered, bonded to the wheel in several layers at a high temperature; the wheel not only lasts longer, but continually exposes fresh layers of abrasive as you work, ensuring a long service life. The cut-off wheel features a fully sintered diamond surface, allowing you to grind and shape workpieces. The 50-micron diamond surface and edge cut cleanly, removing material while leaving a smooth polished surface; cut-off wheels are ideal for slicing stone, metal and acrylic. Edenta superflex cut-off wheels are slightly flexible, ideal accommodating workpieces with contours. The shank of each wheel has color-coded band, making it easy for you to quickly identify the one you need. Always use a lubricant, such as BurLife, when using diamond cut-off wheels.
