2.5 mm German Made Diamond Sphere
2.5 mm diameter sphere diamond. The high quality of these diamond burrs make them a bargain at any price. They are the standard to which all other bonded diamonds are compared. We have tried a number of different manufactures over the years but keep coming back to the high quality of these burrs. Our German made 3/32" shank diamonds can all run at speeds up to 60,000 rpm except the 20-304-097W which can run at a maximum speed of 40,000 rpm.
