Carbide Rotary Burrs can be used for cutting, shaping, grinding and also for the removing sharp edges, burrs and excess material (deburring) and this is what we mention with this article.
For drilling holes or cutting a dent in metal a carbide drill or even a carbide end mill, carbide slot drill or possibly a carbide router is necessary rather than carbide burr. For carving into stone you would ideally utilize a Diamond Burr.
1. Carbide Burrs Can be Used on Many Materials
Tungsten Carbide burrs can be utilized on many materials: metals including steel, aluminum and cast iron, all kinds of wood, acrylics, fibreglass and plastics. When suited for soft metals including gold, platinum and silver, carbide burrs are excellent while they lasts a long time without having chipping or breaking.
Steel, Carbon Steel & Stainless Steel
Cast Iron
Aluminium
Titanium
Cobalt
Nickel
Gold, Platinum & Silver
Ceramics
Fibreglass
Plastic, Carbon Fiber Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze
Zinc
Wood
Different cuts of carbide burrs will probably be best suited to particular materials, see the next point below to find out about the several cuts.
2. Carbide Burrs Commonly Appear in Two Cuts; Single Cut and Double Cut
Single cut (one flute) carbide burrs possess a right handed (Up cut) spiral flute. These are generally in combination with stainless steel, hardened steel, copper, surefire, 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 usually are suited for ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials such as plastics and wood. They have more cutting edges and can remove material faster. Double cut are often referrred to as Diamond Cut or Cross Cut (2 flutes cut across one another) leaves a smoother finish than single cut due to producing smaller chips since they cut away the fabric. Use for medium-light stock removal, deburring, finishing and cleaning. A double cut carbide burr is easily the most popular cut and will look at you through most applications.

3. The Various Shapes of Carbide Burrs and ways to Rely on them
Making a decision on what contour around use is dependent upon the profile or cut you are wanting to achieve.
These different shaped burs are certain to get into many a nook and cranny and provide 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 should you use your Carbide Burrs?
The pace from which you utilize your carbide bur in your rotary tool depends on the material you’re using it on and also the contour being produced yet it’s safe to say you no longer need to exceed speeds of 35,000 RPM.
In the event the burs are chipping easily this could be as a result of speed being too slow. However, it’s ideal to start the bur off slow, helping the speed on the way. High speeds may prevent clogging in the flutes of your respective burs.
5. Don’t Apply Excessive Pressure
Like all drill bits and burrs, permit the burr carry out the work and apply merely a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too rapidly, lowering the life of your burr.
6. Carbide Burrs are Harder Than HSS Burrs
Our Carbide Burrs are machine ground from your 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 begin to soften at higher temperatures so carbide is usually a better choice for too long term performance.
7. Keep The Carbide Burr On the go
When utilizing your carbide burr do not maintain it still for too much time because this may prevent the burr from digging and jabbing into the material causing unsightly marks and roughness.
