Just what is a carbide bur useful for? Carbide Burs bring cutting, shaping, grinding and for the removing sharp edges, burrs and excess material (deburring).

For drilling holes or cutting an opening in metal then this carbide drill or even a carbide end mill, carbide slot drill or a carbide router is required rather than a carbide burr. For carving into stone you would ideally work with a Diamond Burr.

Carbide Burrs Can be Used on Many Materials
Tungsten Carbide burrs may be used on many materials: metals including steel, aluminum and certain, all sorts of wood, acrylics, fibreglass and plastics. When used on soft metals like gold, platinum and silver, carbide burrs are perfect as they lasts quite a while without having chipping or breaking.

Steel, Carbon Steel & Metal
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 will likely be best suited to specific materials, begin to see the next point below to discover more on the several cuts.

So what can You employ 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 employ a handpiece that runs true i.e without 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 therefore are used in the aerospace, automotive, dental, metal sculpting, and metal smith industries to call just a few.

Burs (burrs) come in a variety of sizes and shapes, because both versions can be used as different purposes:

Arch ball/pointed nose – engraving, texturing, increasing hole size
Ball – concave cuts, hollowing, shaping, carving. A good choice 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 (often known as tapered) – concave cuts and rounding edges
Cone – rounding edges, surface finishing, tight spaces, difficult to reach areas.
Cylindrical – contour finishing and right-angled corners
Cylindrical end cut – contour finishing
Carbide Cylindrical no end 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, entry to hard-to-reach areas, and acute angles.
Rounded tree – concave cuts and rounding edges
