Carbide Rotary Burrs bring cutting, shaping, grinding but for the removal of sharp edges, burrs and excess material (deburring) and that is what we should speak about in the following article.
For drilling holes or cutting a dent in metal then a carbide drill or a carbide end mill, carbide slot drill or perhaps a carbide router is essential rather than a carbide burr. For carving into stone you’d ideally work with a Diamond Burr.
1. Carbide Burrs Can be Used on Many Materials
Tungsten Carbide burrs may be used on many materials: metals including steel, aluminum and certain, all types of wood, acrylics, fibreglass and plastics. When suited for soft metals including gold, platinum and silver, carbide burrs are great since they will last quite a while without any chipping or breaking.
Steel, Carbon Steel & Stainless-steel

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 is going to be suitable to a particular materials, start to see the next point below to find out about different cuts.
2. Carbide Burrs Commonly Come in Two Cuts; Single Cut and Double Cut
Single cut (one flute) carbide burrs have a right handed (Up cut) spiral flute. These are usually used with stainless steel, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly having a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Creates long chips
Double cut carbide burrs are usually used on ferrous and non ferrous metals, aluminium, soft steel and for all non-metal materials for example plastics and wood. They’ve got more cutting edges and may remove material faster. Double cut are sometimes referrred to as Diamond Cut or Cross Cut (2 flutes cut across the other person) will leave a smoother finish than single cut because of producing smaller chips since they cut away the pad. Use for medium-light stock removal, deburring, finishing and cleaning. A double cut carbide burr is the most popular cut and definately will see you through most applications.

3. The different Shapes of Carbide Burrs and ways to Utilize them
Making a decision on what contour around use is dependent upon the profile or cut you want to achieve.
These different shaped burs will get into many a nook and cranny and provide some interesting profiles.

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 rate of which you utilize your carbide bur within your rotary tool is determined by the information you’re using it on and also the contour being produced but it’s safe to assume you don’t need to exceed speeds of 35,000 RPM.
If the burs are chipping easily this might be due to the speed being not fast enough. However, it’s ideal to get started on the bur off slow, helping the speed as you go along. High speeds will prevent clogging from the flutes of one’s burs.
5. Tend not to Apply A lot of Pressure
As with every drill bits and burrs, allow burr do the work and apply just a little pressure otherwise the cutting edges with the flutes will chip away or become smooth prematurely, minimizing the life of your burr.
6. Carbide Burrs are not as easy Than HSS Burrs
Our Carbide Burrs are machine ground from the specially chosen grade of carbide. Due to extreme hardness of the Tungsten Carbide they can be utilized on considerably more demanding jobs than HSS (High-speed Steel).
Carbide Burrs also perform better at higher temperatures than HSS so that you can run them hotter, and for longer.
HSS burrs will start to soften at higher temperatures so carbide is obviously a better choice for long term performance.
7. Keep The Carbide Burr On the go
When you use your carbide burr never maintain it still for too long because this may prevent the burr from digging and jabbing in your material causing unsightly marks and roughness.
