Carbide Burrs (also called Rotary Burrs) are used for cutting, shaping, grinding and for the removing sharp edges, burrs and excess material (deburring).
1. What material can Carbide Burrs provide on?
Carbide burrs can be utilized on many materials. Metals including steel, aluminum and cast iron, various wood, acrylics, fibreglass and plastics. When utilized on soft metals like gold, platinum and silver, carbide burrs are great because they lasts quite a while without having chipping or breaking.
Steel, Carbon Steel & Stainless-steel
Certain
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 will likely be suitable to certain materials, understand the next point below to discover more about the several cuts.
What can You employ Carbide Burrs In?
Ideally carbide burrs are widely-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 use 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 utilized in the aerospace, automotive, dental, metal sculpting, and metal smith industries to call 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 very right handed (Up cut) spiral flute. These usually are used with stainless-steel, hardened steel, copper, surefire, and ferrous metals and definately will remove material quickly using 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 tend to be suited for ferrous and non ferrous metals, aluminium, soft steel as well as all non-metal materials for example plastics and wood. They have more cutting edges and can remove material faster. Double cut are often referrred to as Diamond Cut or Cross Cut (2 flutes cut across the other person) will leave a smoother finish than single cut as a result of producing smaller chips because they cut away the pad. Use for medium-light stock removal, deburring, finishing and cleaning. A double cut carbide burr is the most popular cut and will help you through most applications.
Medium- light removing material
Deburring
Fine finishing
Cleaning
Smooth finish
Creates small chips
3. What Speed or RPM the use of your Carbide Burrs?
The rate of which you employ your carbide bur with your rotary tool depends on the information you’ve it on along with the contour being produced however it is safe to assume you do not need to exceed speeds of 35,000 RPM.
4. Usually do not Apply An excessive amount of Pressure
As with all drill bits and burrs, permit the burr perform work and apply simply a little pressure otherwise the cutting edges from the flutes will chip away or become smooth too rapidly, decreasing the use of your burr.
5. Carbide Burrs are Harder Than HSS Burrs
Our Carbide Burrs are machine ground coming from a specially chosen grade of carbide. Because of the extreme hardness in the Tungsten Carbide they can be utilized on far more demanding jobs than HSS (High Speed Steel).
Carbide Burrs also perform better at higher temperatures than HSS so that you can run them hotter, and for longer.
HSS burrs will begin to soften at higher temperatures so carbide is obviously a better choice for very long term performance.
What are Features of Tungsten Carbide Burrs?
Endurance
Use for very long production runs
High stock removal
Perfect for using on many hard and tough materials
Perfect for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings
6. Keep your Carbide Burr On the road
When using your carbide burr don’t ensure that is stays still for too long as this will prevent the burr from digging and jabbing into your material causing unsightly marks and roughness.
End while on an ‘up’ stroke for any smoother finish in your work.
Stay Safe:
Always be sure that your burr shank is well inserted into your collet and clamped down tightly
Keep pressure light whilst the bur moving, emphasizing the very best material first
Make sure your work is secured tightly for your workbench
Don’t snag or jam your burr in your work
Wear eye protection at the least, but better yet use a full shield to your face
