Carbide Rotary Burrs are used for cutting, shaping, grinding but for the removing sharp edges, burrs and excess material (deburring) which is what we mention with this article.

For drilling holes or cutting a hole in metal a carbide drill or even a carbide end mill, carbide slot drill or possibly a carbide router is needed instead of a carbide burr. For carving into stone you would ideally use a Diamond Burr.

1. Carbide Burrs Can be utilized on Many Materials
Tungsten Carbide burrs works extremely well on many materials: metals including steel, aluminum and iron, all types of wood, acrylics, fibreglass and plastics. When used on soft metals for example gold, platinum and silver, carbide burrs are perfect as they can last quite a while without chipping or breaking.

Different cuts of carbide burrs will likely be suitable to specific materials, start to see the next point below to find out about the different cuts.

2. Carbide Burrs Commonly Can be found in Two Cuts; Single Cut and Double Cut
Single cut (one flute) carbide burrs possess a right handed (Up cut) spiral flute. These tend to be combined with stainless steel, hardened steel, copper, cast iron, and ferrous metals and may remove material quickly using a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

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

3. The different Shapes of Carbide Burrs and How To Apply them
Developer what shape to use depends on the profile or cut you are looking to achieve.

These different shaped burs are certain to get into many a nook and cranny and produce some interesting profiles.

4. What Speed or RPM the use of your Carbide Burrs?
The rate of which you employ your carbide bur in your rotary tool is determined by the fabric you’re using it on as well as the contour being produced but it’s pretty sure you don’t need to exceed speeds of 35,000 RPM.

In the event the burs are chipping easily this could be due to speed being not fast enough. However, it’s ideal to start out the bur off slow, increasing the speed on the way. High speeds will prevent clogging inside the flutes of one’s burs.

5. Don’t Apply Too Much Pressure
As with every drill bits and burrs, allow the burr do the work and apply only a little pressure otherwise the cutting edges with the flutes will chip away or become smooth too rapidly, reducing the time of your burr.

6. Carbide Burrs are Harder Than HSS Burrs
Our Carbide Burrs are machine ground coming from a specially chosen grade of carbide. Due to the extreme hardness from the Tungsten Carbide they are often used on a lot more demanding jobs than HSS (Very fast 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 more sensible choice for long term performance.

7. Maintain your Carbide Burr On The Move
When utilizing your carbide burr never maintain it still for too long because this will prevent the burr from digging and jabbing into the material causing unsightly marks and roughness.
