Exactly what is a carbide bur employed for? Carbide Burs can be used for cutting, shaping, grinding and for the removing sharp edges, burrs and excess material (deburring).

For drilling holes or cutting a hole in metal then a carbide drill or possibly a carbide end mill, carbide slot drill or a carbide router is required rather than a carbide burr. For carving into stone you’d ideally work with a Diamond Burr.

Carbide Burrs Can be utilized on Many Materials
Tungsten Carbide burrs can be utilized on many materials: metals including steel, aluminum and certain, all kinds of wood, acrylics, fibreglass and plastics. When suited for soft metals for example gold, platinum and silver, carbide burrs are great since they last quite a while without any chipping or breaking.

Steel, Carbon Steel & Stainless Steel
Iron
Aluminium
Titanium
Cobalt
Nickel
Gold, Platinum & Silver
Ceramics
Fibreglass
Plastic, Carbon Fiber Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze

Different cuts of carbide burrs will probably be most suitable to certain materials, start to see the next point below to discover more on the different cuts.

So what can You have Carbide Burs 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 like a Dremel.

Always use a handpiece that runs true i.e without having wobble.

Who Uses Carbide Burs?
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 they are utilized in the aerospace, automotive, dental, metal sculpting, and metal smith industries to mention only a few.

Burs (burrs) are available in many different shapes and sizes, as both versions bring different purposes:

Arch ball/pointed nose – engraving, texturing, increasing hole size
Ball – concave cuts, hollowing, shaping, carving. Helpful for wood, stone, metal engraving.
Ball nose cone – rounding edges, surface finishing, tight spaces, and angles.
Carbide Ball nose cylinder- contour finishing
Ball nose tree (also known as tapered) – concave cuts and rounding edges
Cone – rounding edges, surface finishing, tight spaces, hard to reach areas.
Cylindrical – contour finishing and right-angled corners
Cylindrical end cut – contour finishing
Carbide Cylindrical a massive array cut – contour finishing
Flame – channel work and shaping
Inverted cone – v-cuts and rear-side chamfering
Oval – die grinding and engraving
Pointed tree – concave cuts, rounding edges, usage of hard-to-reach areas, and acute angles.
Rounded tree – concave cuts and rounding edges
