Description and Comparison of Burrs
– Burrs are rotary analogs to files, cutting linearly.
– They are comparable to endmills and router bits.
– Burrs are often used freehand, while endmills and router bits have machine-controlled toolpaths.
– There is overlap in the use and toolpath control of these cutters.
– Burrs can be used in CNC machining centers for removing burrs after machining.
Use and Speed of Burrs
– Burrs are spun quickly to maintain ideal surface speed and cutting conditions.
– They operate at higher speeds than comparable HSS cutters.
– Tungsten carbide construction allows for higher speeds and maintained cutting edges.
– The small size of burr cutting edges allows them to be touched when spinning without cutting the skin.
– Burrs are suitable for use in dentistry as they can grind hard enamel without harming soft mouth tissues.

Burrs or burs (sometimes called rotary files) are small cutting tools; not to be confused with small pieces of metal formed from cutting metal, used in die grinders, rotary tools, or dental drills. The name may be considered appropriate when their small-sized head (3 mm diameter shaft) is compared to a bur (fruit seed with hooks) or their teeth are compared to a metal burr.
