A Carbide burr is a tungsten carbide rotary deburring tool that has many flutes and cutting edges. They act like rotary files. There are many shapes and sizes of burrs. The different shapes come in single cut, double cut and aluminum cut. Single cut provides the best surface finish and the largest surface contact with the work piece. They demand greater operator skill because the flute direction pulls the burr into the workpiece. Double cut is the most popular as the dual flute direction reduces the contact area on the work piece. Therefore, these burrs provide easier operator control while still maintaining a good surface finish. An aluminum cut burr is a carbide burr for aluminum deburring. They have a coarser flute which results in improved cutting performance. A carbide burr bit is a versatile tool used in Dremel tools as well as many hand held rotary machines.
