Abstract

A surgical bur (20) having a shaft (24) with a bur head (22) at the distal end. A number of flutes are formed on the bur head. Each flute has a cutting edge (54). Two flutes (30, 38) are arcuately symmetrically spaced from one another having cutting edges that start at or approximately, close to the distal end tip (23).and have intermediate sets of flutes (32, 34, 36, 40, 42, 44) therebetween. The intermediate sets of flutes have chamfers (56, 60, 62, 64) so as to progressively engage flute cutting edges into the tissue that is to be excised. The cutting edge progression during the use of the bur decreases or eliminates chatter.
