Carbide Burrs (also called Rotary Burrs) can be used cutting, shaping, grinding and also for the eliminating sharp edges, burrs and excess material (deburring).
1. What material can Carbide Burrs be used on?
Carbide burrs works extremely well on many materials. Metals including steel, aluminum and cast iron, various wood, acrylics, fibreglass and plastics. When used on soft metals such as gold, platinum and silver, carbide burrs are perfect because they will last a very long time without chipping or breaking.
Steel, Carbon Steel & Metal
Iron
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 be best suited to specific materials, see the next point below to discover more about the different cuts.
So what can You have Carbide Burrs In?
Ideally carbide burrs are utilized in Air Tools i.e Die Grinders, Pneumatic rotary tools and high speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools for instance a Dremel.
Always employ a handpiece that runs true i.e without any 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 therefore are used 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 have a very right handed (Up cut) spiral flute. These are usually combined with stainless-steel, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly having a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

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 for all non-metal materials including plastics and wood. They’ve got more cutting edges and may remove material faster. Double cut are sometimes referrred to as Diamond Cut or Cross Cut (2 flutes cut across each other) leaves a smoother finish than single cut due to producing smaller chips as they cut away the information. Use for medium-light stock removal, deburring, finishing and cleaning. A dual cut carbide burr is easily the most popular cut and can view you through most applications.

3. What Speed or RPM should you use your Carbide Burrs?
The velocity at which you utilize your carbide bur within your rotary tool is dependent upon the information you use it on and the contour being produced however it is pretty sure you don’t need to exceed speeds of 35,000 RPM.
4. Do Not Apply An excessive amount of Pressure
As with every drill bits and burrs, allow burr perform the work and apply merely a little pressure otherwise the cutting edges with 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 from a specially chosen grade of carbide. Due to the extreme hardness in the Tungsten Carbide they may be suited for considerably more demanding jobs than HSS (Very fast Steel).
Carbide Burrs also perform better at higher temperatures than HSS to help you run them hotter, as well as for longer.
HSS burrs will begin to soften at higher temperatures so carbide is obviously a more sensible choice for very long term performance.
What Are The Attributes of Tungsten Carbide Burrs?
Long life
Use for too long production runs
High stock removal
Perfect for using on many hard and hard materials
Ideal for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings
6. Keep your Carbide Burr On the go
When using your carbide burr don’t ensure that it stays still for days since this prevents the burr from digging and jabbing into your material causing unsightly marks and roughness.
End by using an ‘up’ stroke for the smoother finish on your work.
Stay Safe:
Always keep your burr shank is well inserted into your collet and clamped down tightly
Keep pressure light and make the bur moving, centering on the greatest material first
Keep your jobs are secured tightly to your work bench
Don’t snag or jam your burr in your work
Wear eye protection at the very least, but on top of that use a full shield for your face
