Carbide Burrs (often known as Rotary Burrs) can be used cutting, shaping, grinding and also for the elimination of sharp edges, burrs and excess material (deburring).
1. What material can Carbide Burrs be utilized on?
Carbide burrs may be used on many materials. Metals including steel, aluminum and certain, all types of wood, acrylics, fibreglass and plastics. When applied to soft metals like gold, platinum and silver, carbide burrs are perfect while they last a long time with no chipping or breaking.
Steel, Carbon Steel & Metal
Iron
Aluminium
Titanium
Cobalt
Nickel
Gold, Platinum & Silver
Ceramics
Fibreglass
Plastic, Graphite Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze
Zinc
Wood
Different cuts of carbide burrs will likely be ideal to certain materials, begin to see the next point below to find out about the several cuts.
What Do You have Carbide Burrs In?
Ideally carbide burrs are used in Air Tools i.e Die Grinders, Pneumatic rotary tools and also speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools such as a Dremel.
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 are found in the aerospace, automotive, dental, metal sculpting, and metal smith industries to only a few.
2. Carbide Burrs Commonly Are available in Two Cuts; Single Cut and Double Cut (Diamond Cut)
Single cut (one flute) carbide burrs have a very right handed (Up cut) spiral flute. These tend to be combined with stainless-steel, hardened steel, copper, iron, and ferrous metals and will remove material quickly with a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.
Heavy removing material
Milling
Deburring
Cleaning
Creates long chips
Double cut carbide burrs tend to be suited for ferrous and non ferrous metals, aluminium, soft steel as well as for all non-metal materials including plastics and wood. They’ve got more cutting edges and can remove material faster. Double cut are often referrred to as Diamond Cut or Cross Cut (2 flutes cut across one another) leaves a smoother finish than single cut as a result of producing smaller chips since 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 definately will view you through most applications.
Medium- light elimination of material
Deburring
Fine finishing
Cleaning
Smooth finish
Creates small chips
3. What Speed or RPM should you use your Carbide Burrs?
The velocity where you utilize your carbide bur with your rotary tool will depend on the pad you use it on and also the contour being produced however it is reliable advice you don’t to exceed speeds of 35,000 RPM.
4. Do Not Apply An excessive amount of Pressure
As with every drill bits and burrs, allow the burr carry out the work and apply only a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too quickly, minimizing the life of your burr.
5. Carbide Burrs are not as easy Than HSS Burrs
Our Carbide Burrs are machine ground from the specially chosen grade of carbide. Due to the extreme hardness with the Tungsten Carbide they could be suited for far more demanding jobs than HSS (Very fast Steel).
Carbide Burrs also perform better at higher temperatures than HSS in order to run them hotter, as well as for longer.
HSS burrs will start to soften at higher temperatures so carbide is always a better option for very long term performance.
What are Advantages of Tungsten Carbide Burrs?
Longevity
Use for too long production runs
High stock removal
Perfect for using on many hard and tough materials
Well suited for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings
6. Keep The Carbide Burr On the road
When utilizing your carbide burr do not keep it still for days on end simply because this will prevent the burr from digging and jabbing in your material causing unsightly marks and roughness.
End by using an ‘up’ stroke for the smoother finish for your work.
Stay Safe:
Always ensure your burr shank is well inserted to your collet and clamped down tightly
Keep pressure light and make the bur moving, concentrating on the highest material first
Be sure that your effort is secured tightly in your work bench
Don’t snag or jam your burr to your work
Wear eye protection at least, but better still work with a full shield for your face
