Carbide Burrs (also called Rotary Burrs) are used for cutting, shaping, grinding and also for the removal of sharp edges, burrs and excess material (deburring).
1. What material can Carbide Burrs be used on?
Carbide burrs may be used on many materials. Metals including steel, aluminum and cast iron, all sorts of wood, acrylics, fibreglass and plastics. When suited for soft metals such as gold, platinum and silver, carbide burrs are perfect while they will last a long time without chipping or breaking.
Steel, Carbon Steel & Stainless
Cast 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 is going to be ideal to particular materials, begin to see the next point below to discover more regarding the different cuts.
What Do You employ 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 for instance a Dremel.
Always employ a handpiece that runs true i.e without having 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 therefore are employed in the aerospace, automotive, dental, metal sculpting, and metal smith industries to call but 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 possess a right handed (Up cut) spiral flute. These usually are used with stainless, hardened steel, copper, iron, and ferrous metals and definately will remove material quickly which has a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.

Deburring
Cleaning
Creates long chips
Double cut carbide burrs are generally 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 often referrred to as Diamond Cut or Cross Cut (2 flutes cut across one another) will leave a smoother finish than single cut due to producing smaller chips as they cut away the pad. Use for medium-light stock removal, deburring, finishing and cleaning. A dual cut carbide burr is regarded as the popular cut and definately will help you through most applications.

3. What Speed or RPM should you use your Carbide Burrs?
The velocity of which you have your carbide bur within your rotary tool depends on the fabric you’re using it on along with the contour being produced however it is safe to assume you don’t to exceed speeds of 35,000 RPM.
4. Usually do not Apply An excessive amount of Pressure
As with most drill bits and burrs, allow burr do the work and apply simply a little pressure otherwise the cutting edges from the flutes will chip away or become smooth too quickly, decreasing the lifetime 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. As a result of extreme hardness from the Tungsten Carbide they could be applied to considerably 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 will start to soften at higher temperatures so carbide is always a more sensible choice for very long term performance.
Which are the Attributes of Tungsten Carbide Burrs?
Durability
Use for lengthy production runs
High stock removal
Perfect for using on many hard and hard materials
Perfect for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings
6. Keep your Carbide Burr On the road
When working with your carbide burr don’t keep it still for days on end as this may prevent the burr from digging and jabbing in your material causing unsightly marks and roughness.
End by using an ‘up’ stroke for any smoother finish for your work.
Stay Safe:
Always ensure your burr shank is well inserted into your collet and clamped down tightly
Keep pressure light and make the bur moving, centering on the best material first
Make sure your effort is secured tightly in your workbench
Don’t snag or jam your burr into your work
Wear eye protection at the least, but on top of that use a full shield to your face
