Carbide Burrs (also referred to as Rotary Burrs) can be used cutting, shaping, grinding but for the elimination of sharp edges, burrs and excess material (deburring).
1. What material can Carbide Burrs supply on?
Carbide burrs works extremely well on many materials. Metals including steel, aluminum and surefire, various wood, acrylics, fibreglass and plastics. When utilized on soft metals such as gold, platinum and silver, carbide burrs are excellent because they last a very long time without having 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 will probably be most suitable to particular materials, understand the next point below to find out about different cuts.
What can You utilize 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 say for example a Dremel.
Always employ a handpiece that runs true i.e with no 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 found in the aerospace, automotive, dental, metal sculpting, and metal smith industries to mention just some.
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 used in combination with stainless steel, 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.
Heavy elimination of material
Milling
Deburring
Cleaning
Creates long chips
Double cut carbide burrs are generally applied to ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials like plastics and wood. They have more cutting edges and may remove material faster. Double cut are often referrred to as Diamond Cut or Cross Cut (2 flutes cut across one another) will leave a smoother finish than single cut due to producing smaller chips while they cut away the material. Use for medium-light stock removal, deburring, finishing and cleaning. A double cut carbide burr is easily the most popular cut and definately will view you through most applications.

3. What Speed or RPM should you use your Carbide Burrs?
The rate from which you have your carbide bur with your rotary tool will depend on the pad you use it on and also the contour being produced but it is safe to assume you no longer need to exceed speeds of 35,000 RPM.
4. Don’t Apply A lot of Pressure
Like all drill bits and burrs, let the burr perform the work and apply only a little pressure otherwise the cutting edges of the flutes will chip away or become smooth prematurely, lowering the lifetime of your burr.
5. 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 from 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 for longer.
HSS burrs will start to soften at higher temperatures so carbide is usually a better option for long term performance.
Which are the Attributes of Tungsten Carbide Burrs?
Endurance
Use for long production runs
High stock removal
Perfect for using on many hard and hard materials
Well suited for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings
6. Maintain the Carbide Burr On The Move
When you use your carbide burr do not keep it still for days on end as this may prevent the burr from digging and jabbing into the material causing unsightly marks and roughness.
End while on an ‘up’ stroke to get a smoother finish on your work.
Stay Safe:
Always ensure your burr shank is well inserted to your collet and clamped down tightly
Keep pressure light and the bur moving, centering on the very best material first
Ensure your work is secured tightly for your workbench
Don’t snag or jam your burr to your work
Wear eye protection as a minimum, but better still utilize a full shield to your face
