Seven Facts About Tungsten Carbide Burrs And The Best Way To Use Them

Carbide Rotary Burrs can be used cutting, shaping, grinding and for the removal of sharp edges, burrs and excess material (deburring) which is that which you talk about with this article.

For drilling holes or cutting an opening in metal a carbide drill or perhaps a carbide end mill, carbide slot drill or even a carbide router is essential instead of a carbide burr. For carving into stone you’d ideally utilize 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 cast iron, various wood, acrylics, fibreglass and plastics. When used on soft metals such as gold, platinum and silver, carbide burrs are ideal because they lasts a long time without having chipping or breaking.

Gold, Platinum & Silver
Ceramics
Fibreglass
Plastic, Graphite Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze

2. Carbide Burrs Commonly Come in Two Cuts; Single Cut and Double Cut
Single cut (one flute) carbide burrs possess a right handed (Up cut) spiral flute. These are usually used in combination with stainless, hardened steel, copper, surefire, and ferrous metals and will remove material quickly with 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 also for all non-metal materials such as plastics and wood. They’ve got more cutting edges and will remove material faster. Double cut are often referrred to as Diamond Cut or Cross Cut (2 flutes cut across each other) will leave a smoother finish than single cut on account of producing smaller chips while they cut away the material. Use for medium-light stock removal, deburring, finishing and cleaning. A dual cut carbide burr is easily the most popular cut and may view you through most applications.

3. The different Shapes of Carbide Burrs and How To Rely on them
Making a decision on what contour around use will depend on the profile or cut you are planning to achieve.

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

4. What Speed or RPM should you use your Carbide Burrs?
The pace of which you have your carbide bur inside your rotary tool is determined by the information you’re using it on as well as the contour being produced but it is safe to say you do not need to exceed speeds of 35,000 RPM.

In the event the burs are chipping easily this can be due to the speed being not fast enough. However, it’s ideal to start the bur off slow, increasing the speed during this process. High speeds minimizes clogging in the flutes of one’s burs.

5. Usually do not Apply Excessive Pressure
As with every drill bits and burrs, permit the burr do the work and apply only a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too rapidly, minimizing the life 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. Because of the extreme hardness of the Tungsten Carbide they may be used on much more demanding jobs than HSS (Broadband Steel).

Carbide Burrs also perform better at higher temperatures than HSS to help you run them hotter, and for longer.

HSS burrs will start to soften at higher temperatures so carbide is definitely a more sensible choice for lengthy term performance.

7. Keep The Carbide Burr Moving around
When working with your carbide burr try not to ensure that is stays still for too much time since this minimizes the burr from digging and jabbing in your material causing unsightly marks and roughness.
