Just what is a carbide burr
Carbide burrs are tools utilized for deburring, cutting, shaping, grinding, and chamfering hard materials. Different cuts of carbide burrs will likely be most suitable for sure materials.

Carbide burrs are employed in air tools such as die grinders, pneumatic rotary tools and high-speed engravers, Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools.

The reason to use Carbide burrs over HHS(high-speed steel)?
Carbide comes with a Very high heat tolerance that enables these phones operate at higher speeds than similar HSS cutters, yet still maintain their cutting edges. High-speed steel(HSS) burrs will quickly soften at higher temperatures while carbide Maintains hardness even under compression and it has Longer working life and it is a better option for lengthy term performance due to higher wear resistance.

Single-Cut vs Double-Cut
Single cut Burrs are suitable for General Purpose. It will give good material removal and smooth workpiece finishes.

Single cut is used with stainless steel, hardened steel, copper, cast iron, and ferrous metals and definately will remove material quickly using a smooth finish. Bring Deburring, cleaning, milling, material removal or creating long chips

Double cut Burrs allow for rapid stock removal in harder materials and tougher applications. The designs reduces pulling action, that enables better operator control, and reduces chips

Double cut burrs are used on ferrous and non-ferrous metals, aluminium, soft steel as well as all non-metal materials including stone, plastics, hardwood, and ceramic. This cut has more cutting edges and will remove material faster.

Double-cut will leave a smoother finish than single-cut on account of producing smaller chips since they cut away the information. Use double-cut for medium-light stock removal, deburring, fine finishing, cleaning, smooth finishes, and creating smaller chips. Double cut carbide burrs are the hottest and work for most applications.
