7 Facts About Tungsten Carbide Burrs And Tips On How To Use Them
Carbide Rotary Burrs bring cutting, shaping, grinding and for the eliminating sharp edges, burrs and excess material (deburring) and that is what we should mention in this article.
For drilling holes or cutting an opening in metal then the carbide drill or even a carbide end mill, carbide slot drill or even a carbide router is needed instead of a carbide burr. For carving into stone you’ll ideally use a Diamond Burr.
1. Carbide Burrs May be used on Many Materials
Tungsten Carbide burrs can be used on many materials: metals including steel, aluminum and iron, all kinds of wood, acrylics, fibreglass and plastics. When utilized on soft metals such as gold, platinum and silver, carbide burrs are great because they can last a very long time with no chipping or breaking.

Wood
Different cuts of carbide burrs will probably be most suitable to specific materials, understand the next point below to discover more on the different cuts.
2. Carbide Burrs Commonly Come in Two Cuts; Single Cut and Double Cut
Single cut (one flute) carbide burrs use a right handed (Up cut) spiral flute. These tend to be combined with stainless-steel, hardened steel, copper, iron, and ferrous metals and definately will remove material quickly having a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Creates long chips
Double cut carbide burrs tend to be applied to 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 definately will remove material faster. Double cut are often referrred to as Diamond Cut or Cross Cut (2 flutes cut across each other) leaves a smoother finish than single cut on account of producing smaller chips while they cut away the pad. Use for medium-light stock removal, deburring, finishing and cleaning. A double cut carbide burr is easily the most popular cut and may view you through most applications.

3. The Various Shapes of Carbide Burrs and the way to Apply them
Developer what fit around use is determined by the profile or cut you are wanting to achieve.
These different shaped burs can 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 at which you use your carbide bur in your rotary tool will depend on the material you’ve it on along with the contour being produced however it is pretty sure you don’t to exceed speeds of 35,000 RPM.
If your burs are chipping easily this may be due to the speed being not quick enough. However, it’s ideal to start the bur off slow, helping the speed on the way. High speeds prevents clogging inside the flutes of your respective burs.
5. Do Not Apply Too Much Pressure
As with all drill bits and burrs, let the burr carry out the work and apply simply a little pressure otherwise the cutting edges with the flutes will chip away or become smooth too quickly, decreasing the duration of your burr.
6. Carbide Burrs are not as easy Than HSS Burrs
Our Carbide Burrs are machine ground from your specially chosen grade of carbide. As a result of extreme hardness in the Tungsten Carbide they are often suited for a lot more demanding jobs than HSS (Broadband Steel).
Carbide Burrs also perform better at higher temperatures than HSS so you can run them hotter, as well as longer.
HSS burrs will quickly soften at higher temperatures so carbide is obviously a better option for too long term performance.
7. Keep The Carbide Burr On The Move
When you use your carbide burr never keep it still for days on end because this prevents the burr from digging and jabbing into the material causing unsightly marks and roughness.
