Try one of these tools in your handpiece - and you will be amazed at the ease with which it handles the hardest gold alloys. Even hard steel and glass present no problems to this latest addition to our line of fine burs. Carbide can be subjected to the sort of heavy-duty use and heat build-up that would destroy ordinary burs in a few minutes. They actually perform better at high temperatures and require no lubrication.

Try one - and experience the smoothest results ever provided by a bur; a combination of fine cut and exceptional hardness automatically upgrades the quality of any job. A wide assortment of bearing cutters and setting burs ensures a perfect seat for every setting job. Remaining shapes are coordinated to easily open holes and complete a variety of grinding operations.

Try one - and save time. A bench man need no longer lose time either in constantly changing burs, or in being slowed down by the increasing drag of dull tools. 


Try one - and cut labor costs. A time study in a typical diamond setting shop showed an increase in production from 125 to 400 settings per hour. Jewelry manufacturers and repairers, ranging from small to large, indicate savings averaging over 50% in all operations requiring burs.
