Carbide Burrs (often known as Rotary Burrs) can be used for cutting, shaping, grinding and for the elimination of sharp edges, burrs and excess material (deburring).
1. What material can Carbide Burrs be used on?
Carbide burrs can be used on many materials. Metals including steel, aluminum and iron, all types of wood, acrylics, fibreglass and plastics. When applied to soft metals like gold, platinum and silver, carbide burrs are great as they last a long time without having chipping or breaking.
Steel, Carbon Steel & Metal
Surefire
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 is going to be most suitable to certain materials, see the next point below to find out about different cuts.
What can 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.
Always employ a handpiece that runs true i.e with no wobble.
Who Uses Carbide Burrs?
Carbide burrs are popular for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. And they are utilized in the aerospace, automotive, dental, metal sculpting, and metal smith industries to mention just a few.
2. Carbide Burrs Commonly Can be found 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 are generally used with stainless-steel, hardened steel, copper, iron, and ferrous metals and will remove material quickly which has a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.
Heavy removal of material
Milling
Deburring
Cleaning
Creates long chips
Double cut carbide burrs are usually suited for ferrous and non ferrous metals, aluminium, soft steel as well as all non-metal materials including plastics and wood. They have more cutting edges and will remove material faster. Double cut are sometimes referrred to as Diamond Cut or Cross Cut (2 flutes cut across each other) will leave a smoother finish than single cut as a result 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 will look at you through most applications.

Deburring
Fine finishing
Cleaning
Smooth finish
Creates small chips
3. What Speed or RPM the use of your Carbide Burrs?
The pace where you employ your carbide bur inside your rotary tool is determined by the pad you use it on along with the contour being produced but it is safe to say you don’t to exceed speeds of 35,000 RPM.
4. Usually do not Apply A lot of Pressure
As with every drill bits and burrs, permit the burr carry out the work and apply merely a little pressure otherwise the cutting edges of the flutes will chip away or become smooth prematurely, 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 in the Tungsten Carbide they may be applied to a lot 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 longer.
HSS burrs will begin to soften at higher temperatures so carbide is obviously a more sensible choice for lengthy term performance.
What are Attributes of Tungsten Carbide Burrs?
Durability
Use for lengthy production runs
High stock removal
Ideal for using on many hard and difficult materials
Ideal for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings
6. Keep The Carbide Burr On The Move
When utilizing your carbide burr don’t ensure that is stays still for too much time as this minimizes the burr from digging and jabbing into the material causing unsightly marks and roughness.
End by using an ‘up’ stroke for a smoother finish for your work.
Stay Safe:
Always make sure your burr shank is well inserted into your collet and clamped down tightly
Keep pressure light and make the bur moving, concentrating on the greatest material first
Ensure your effort is secured tightly in your work bench
Don’t snag or jam your burr to your work
Wear eye protection at the very least, but better still make use of a full shield for your face
