The coated bur surface is very smooth which reduces friction. Therefore a cooler bur reduces or eliminates clogging.
The coated bur is sharper which means the appliances can be trimmed and finished quicker.
These special coated burs have been developed for use with all heat cure and cold cured acrylics. They have all the features listed above, therefore making this range the ideal bur for your laboratory.
