Carbide Burrs (also called Rotary Burrs) are used for 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 kinds of wood, acrylics, fibreglass and plastics. When applied to soft metals for example gold, platinum and silver, carbide burrs are great since they lasts quite a while with no chipping or breaking.
Steel, Carbon Steel & Metal
Iron
Aluminium
Titanium
Cobalt
Nickel
Gold, Platinum & Silver
Ceramics
Fibreglass
Plastic, Carbon fibre Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze
Zinc
Wood
Different cuts of carbide burrs will be suitable to particular materials, see the next point below to discover more on the different cuts.
Exactly what do You employ Carbide Burrs In?
Ideally carbide burrs are widely-used in Air Tools i.e Die Grinders, Pneumatic rotary tools and speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools for instance a Dremel.
Only use a handpiece that runs true i.e with no wobble.
Who Uses Carbide Burrs?
Carbide burrs are trusted for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. And they are found in the aerospace, automotive, dental, metal sculpting, and metal smith industries to only a few.
2. Carbide Burrs Commonly Come in Two Cuts; Single Cut and Double Cut (Diamond 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 which has a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Milling
Deburring
Cleaning
Creates long chips
Double cut carbide burrs are usually applied to ferrous and non ferrous metals, aluminium, soft steel and for all non-metal materials including plastics and wood. They have more cutting edges and may remove material faster. Double cut are sometimes referrred to as Diamond Cut or Cross Cut (2 flutes cut across the other person) leaves a smoother finish than single cut because of 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 among the most popular cut and may view you through most applications.

3. What Speed or RPM if you work with your Carbide Burrs?
The rate where you employ your carbide bur inside your rotary tool depends on the material you have it on and also the contour being produced yet it’s safe to assume you no longer need to exceed speeds of 35,000 RPM.
4. Do Not Apply Excessive Pressure
As with every drill bits and burrs, allow burr perform the work and apply simply a little pressure otherwise the cutting edges from the flutes will chip away or become smooth prematurely, minimizing the use 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 extreme hardness in the Tungsten Carbide they could be utilized on considerably more demanding jobs than HSS (Very fast Steel).
Carbide Burrs also perform better at higher temperatures than HSS so that you can run them hotter, and then for longer.
HSS burrs will start to soften at higher temperatures so carbide is obviously a better option for too long term performance.
Do you know the Advantages of Tungsten Carbide Burrs?
Longevity
Use for long production runs
High stock removal
Suitable for using on many hard and tough materials
Suitable for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings
6. Maintain your Carbide Burr Moving around
When you use your carbide burr never ensure that is stays still for days as this minimizes the burr from digging and jabbing to your material causing unsightly marks and roughness.
End with an ‘up’ stroke for a smoother finish in your work.
Stay Safe:
Always keep your burr shank is well inserted into the collet and clamped down tightly
Keep pressure light and keep the bur moving, centering on the greatest material first
Keep your tasks are secured tightly to your workbench
Don’t snag or jam your burr into your work
Wear eye protection at least, but on top of that use a full shield for your face
