Carbide Rotary Burrs can be used for cutting, shaping, grinding and for the eliminating sharp edges, burrs and excess material (deburring) which is what we discuss with this article.
For drilling holes or cutting a hole in metal then the carbide drill or perhaps a carbide end mill, carbide slot drill or possibly a carbide router is required rather than a carbide burr. For carving into stone you would ideally make use of a Diamond Burr.
1. Carbide Burrs Works extremely well on Many Materials
Tungsten Carbide burrs can be used on many materials: metals including steel, aluminum and surefire, all types of wood, acrylics, fibreglass and plastics. When applied to soft metals for example gold, platinum and silver, carbide burrs are great because they will last quite a long time without having chipping or breaking.

Different cuts of carbide burrs is going to be suitable to a particular materials, see the next point below to discover more regarding the several cuts.
2. Carbide Burrs Commonly Can be found in Two Cuts; Single Cut and Double Cut
Single cut (one flute) carbide burrs use a right handed (Up cut) spiral flute. These are usually combined with metal, hardened steel, copper, iron, and ferrous metals and can remove material quickly which has a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Deburring

Creates long chips
Double cut carbide burrs are usually suited for ferrous and non ferrous metals, aluminium, soft steel as well as for all non-metal materials for example plastics and wood. They’ve got more cutting edges and definately will remove material faster. Double cut are occasionally referrred to as Diamond Cut or Cross Cut (2 flutes cut across one another) leaves a smoother finish than single cut as a result of producing smaller chips since they cut away the material. Use for medium-light stock removal, deburring, finishing and cleaning. A double cut carbide burr is among the most popular cut and can look at you through most applications.

3. Various Shapes of Carbide Burrs and ways to Use Them
Developer what shape to use depends on the profile or cut you are wanting to achieve.
These different shaped burs is certain to get into many a nook and cranny and produce some interesting profiles.

Carbide Inverted Cone Burrs
Carbide Pointed Cone & Carbide Round Nose or Ball Nose Burrs
Cylinder Burrs. Round Nose/Ball nose/End Cut
Oval Burrs
Flame Burrs
Countersink Burrs
4. What Speed or RPM if you work with your Carbide Burrs?
The speed where you use your carbide bur with your rotary tool will depend on the information you’ve it on and also the contour being produced yet it’s safe to say you don’t to exceed speeds of 35,000 RPM.
When the burs are chipping easily this may be as a result of speed being too slow. However, it’s ideal to start out the bur off slow, increasing the speed on the way. High speeds may prevent clogging from the flutes of the burs.
5. Usually do not Apply Excessive Pressure
As with every drill bits and burrs, let the burr perform the work and apply merely a little pressure otherwise the cutting edges from the flutes will chip away or become smooth too soon, lowering the lifetime of your burr.
6. Carbide Burrs are Harder Than HSS Burrs
Our Carbide Burrs are machine ground from the specially chosen grade of carbide. As a result of extreme hardness of the Tungsten Carbide they may be used on considerably more demanding jobs than HSS (High-speed Steel).
Carbide Burrs also perform better at higher temperatures than HSS so you can run them hotter, as well as for longer.
HSS burrs will quickly soften at higher temperatures so carbide is always a better option for very long term performance.
7. Maintain the Carbide Burr On The Move
When working with your carbide burr never keep it still for days on end since this may prevent the burr from digging and jabbing into the material causing unsightly marks and roughness.
