7 Points About Tungsten Carbide Burrs And How To Use Them
Carbide Rotary Burrs can be used cutting, shaping, grinding and also for the removal of sharp edges, burrs and excess material (deburring) and that is what we should discuss in the following article.
For drilling holes or cutting a hole in metal then a carbide drill or a carbide end mill, carbide slot drill or possibly a carbide router is necessary rather than a carbide burr. For carving into stone you’d probably ideally work with a Diamond Burr.
1. Carbide Burrs Can be Used on Many Materials
Tungsten Carbide burrs can be used on many materials: metals including steel, aluminum and certain, all types of wood, acrylics, fibreglass and plastics. When suited for soft metals such as gold, platinum and silver, carbide burrs are ideal because they last quite a while without having chipping or breaking.

Different cuts of carbide burrs will likely be suitable to certain materials, begin to see the next point below to discover more on the different cuts.
2. Carbide Burrs Commonly Are available in Two Cuts; Single Cut and Double Cut
Single cut (one flute) carbide burrs use a right handed (Up cut) spiral flute. These are generally used with stainless-steel, hardened steel, copper, certain, and ferrous metals and will remove material quickly with a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Deburring

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

3. Various Shapes of Carbide Burrs and ways to Utilize them
Developer what shape to use is dependent upon the profile or cut you are looking to achieve.
These different shaped burs can get into many a nook and cranny and produce some interesting profiles.

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 velocity at which you employ your carbide bur inside your rotary tool will depend on the material you use it on as well as the contour being produced yet it’s pretty sure you no longer need to exceed speeds of 35,000 RPM.
If the burs are chipping easily this could be due to the speed being not fast enough. However, it’s ideal to start the bur off slow, increasing the speed on the way. High speeds may prevent clogging within the flutes of one’s burs.
5. Usually do not Apply Too Much Pressure
As with every drill bits and burrs, let the burr do the work and apply simply a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too rapidly, reducing the lifetime 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. Because of the extreme hardness in the Tungsten Carbide they can be suited for much more demanding jobs than HSS (Very fast Steel).
Carbide Burrs also perform better at higher temperatures than HSS in order to run them hotter, and then for longer.
HSS burrs will begin to soften at higher temperatures so carbide is obviously a better option for long term performance.
7. Maintain your Carbide Burr Moving around
When you use your carbide burr do not ensure that is stays still for too long because this will prevent the burr from digging and jabbing to your material causing unsightly marks and roughness.
