Carbide Burrs (also known as Rotary Burrs) are used for cutting, shaping, grinding but for the removal of sharp edges, burrs and excess material (deburring).
1. What material can Carbide Burrs be utilized on?
Carbide burrs works extremely well on many materials. Metals including steel, aluminum and certain, all types of wood, acrylics, fibreglass and plastics. When used on soft metals including gold, platinum and silver, carbide burrs are excellent while they can last quite a while without having chipping or breaking.
Steel, Carbon Steel & Stainless Steel
Surefire
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 ideal to specific materials, begin to see the next point below to discover more about the different cuts.
Exactly what do You utilize Carbide Burrs In?
Ideally carbide burrs are used in Air Tools i.e Die Grinders, Pneumatic rotary tools as well as 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 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 name but a few.
2. Carbide Burrs Commonly Appear in Two Cuts; Single Cut and Double Cut (Diamond Cut)
Single cut (one flute) carbide burrs have a right handed (Up cut) spiral flute. These usually are combined with stainless-steel, hardened steel, copper, surefire, and ferrous metals and can 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 usually are utilized on ferrous and non ferrous metals, aluminium, soft steel and for all non-metal materials including plastics and wood. They’ve got more cutting edges and can 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 on account of producing smaller chips as 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 can look at you through most applications.

3. What Speed or RPM the use of your Carbide Burrs?
The rate from which you employ your carbide bur in your rotary tool will depend on the fabric you’ve it on along with the contour being produced however it is reliable advice you do not need to exceed speeds of 35,000 RPM.
4. Don’t Apply Too Much Pressure
Like all drill bits and burrs, let the burr perform work and apply just a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too soon, lowering the life of your burr.
5. Carbide Burrs are Harder Than HSS Burrs
Our Carbide Burrs are machine ground from your specially chosen grade of carbide. Because of the extreme hardness in the Tungsten Carbide they could be applied to far more demanding jobs than HSS (High Speed Steel).
Carbide Burrs also perform better at higher temperatures than HSS to help you run them hotter, as well as longer.
HSS burrs are going to soften at higher temperatures so carbide is always a better option for long term performance.
Which are the Attributes of Tungsten Carbide Burrs?
Longevity
Use for long production runs
High stock removal
Ideal 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 On the road
When working with your carbide burr do not ensure that it stays still for days on end since this prevents the burr from digging and jabbing to your material causing unsightly marks and roughness.
End by using an ‘up’ stroke to get a smoother finish to your work.
Stay Safe:
Always keep your burr shank is well inserted into the collet and clamped down tightly
Keep pressure light and the bur moving, concentrating on the highest material first
Make sure your effort is secured tightly to your workbench
Don’t snag or jam your burr in your work
Wear eye protection at least, but better still use a full shield for the face
