These burrs are a useful shape for chamferring edges and dressing corner welds.
Carbide burs with oval, or teardrop, tips are useful for shaping, especially on curved surfaces. They can also leave a neat finish on a corner fillet weld. All sizes in this shape are for steel and hard alloys. There is an option of a 3mm spindle for Dremels and craft tools, otherwise most have 6mm spindles for use on die-grinders. There is also an 8mm spindle option which may be preferred in drill chucks.
