Just what carbide burr
Carbide burrs are tools utilized for deburring, cutting, shaping, grinding, and chamfering hard materials. Different cuts of carbide burrs will probably be best suited for several materials.

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

Why do you use Carbide burrs over HHS(high-speed steel)?
Carbide comes with an Elevated heat tolerance that enables them to operate at higher speeds than similar HSS cutters, though maintain their cutting edges. High-speed steel(HSS) burrs will quickly soften at higher temperatures while carbide Maintains hardness even under compression and has Longer working life and it is a more sensible choice for lengthy term performance because of higher wear resistance.

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

Single cut can be used with metal, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly having a smooth finish. Can be used Deburring, cleaning, milling, material removal or creating long chips

Double cut Burrs enable 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 employed on ferrous and non-ferrous metals, aluminium, soft steel and also for all non-metal materials such as stone, plastics, hardwood, and ceramic. This cut has more cutting edges and will remove material faster.

Double-cut leaves a smoother finish than single-cut due to producing smaller chips as they cut away the material. Use double-cut for medium-light stock removal, deburring, fine finishing, cleaning, smooth finishes, and creating smaller chips. Double cut carbide burrs include the most popular and work with most applications.
