Carbide Burrs (also referred to as Rotary Burrs) are used for cutting, shaping, grinding and for the removal of sharp edges, burrs and excess material (deburring).
1. What material can Carbide Burrs supply on?
Carbide burrs can be used on many materials. Metals including steel, aluminum and certain, all kinds of wood, acrylics, fibreglass and plastics. When used on soft metals such as gold, platinum and silver, carbide burrs are ideal since they lasts quite a long time without chipping or breaking.
Steel, Carbon Steel & Metal
Surefire
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 specific materials, begin to see the next point below to find out about the different cuts.
So what can You Use Carbide Burrs In?
Ideally carbide burrs are employed in Air Tools i.e Die Grinders, Pneumatic rotary tools and also speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools like a Dremel.
Always use a handpiece that runs true i.e without wobble.
Who Uses Carbide Burrs?
Carbide burrs are widely used for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. And so are utilized in the aerospace, automotive, dental, metal sculpting, and metal smith industries to name but a few.
2. Carbide Burrs Commonly Appear in Two Cuts; Single Cut and Double Cut (Diamond Cut)
Single cut (one flute) carbide burrs use a right handed (Up cut) spiral flute. These usually are combined with stainless-steel, hardened steel, copper, iron, and ferrous metals and may remove material quickly having a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.
Heavy elimination of material
Milling
Deburring
Cleaning
Creates long chips
Double cut carbide burrs are usually suited for ferrous and non ferrous metals, aluminium, soft steel and also 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 because of producing smaller chips because they cut away the information. Use for medium-light stock removal, deburring, finishing and cleaning. A dual cut carbide burr is the most popular cut and can see you through most applications.

3. What Speed or RPM should you use your Carbide Burrs?
The rate of which you utilize your carbide bur inside your rotary tool depends on the information you’re using it on as well as the contour being produced but it’s reliable advice you don’t need to exceed speeds of 35,000 RPM.
4. Don’t Apply Too Much Pressure
As with all drill bits and burrs, allow the burr do the work and apply simply a little pressure otherwise the cutting edges from the flutes will chip away or become smooth too soon, decreasing the life of your burr.
5. Carbide Burrs are not as easy Than HSS Burrs
Our Carbide Burrs are machine ground coming from a specially chosen grade of carbide. Due to the extreme hardness of the Tungsten Carbide they are often used on considerably more demanding jobs than HSS (Broadband Steel).
Carbide Burrs also perform better at higher temperatures than HSS in order to run them hotter, as well as longer.
HSS burrs will start to soften at higher temperatures so carbide is usually a better choice for very long term performance.
What Are The Advantages of Tungsten Carbide Burrs?
Long life
Use for long production runs
High stock removal
Ideal for using on many hard and hard materials
Well suited for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings
6. Keep your Carbide Burr On the road
When you use your carbide burr try not to ensure that is stays still for days on end since this will prevent the burr from digging and jabbing into your material causing unsightly marks and roughness.
End with an ‘up’ stroke to get a smoother finish on your work.
Stay Safe:
Always keep your burr shank is well inserted to your collet and clamped down tightly
Keep pressure light and keep the bur moving, focusing on the very best material first
Ensure your work is secured tightly in your workbench
Don’t snag or jam your burr in your work
Wear eye protection as a minimum, but better yet work with a full shield for your face
