What is a carbide bur employed for? Carbide Burs can be used for cutting, shaping, grinding but for the elimination of sharp edges, burrs and excess material (deburring).

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

Carbide Burrs Can be Used on Many Materials
Tungsten Carbide burrs can be used on many materials: metals including steel, aluminum and surefire, all types of wood, acrylics, fibreglass and plastics. When utilized on soft metals including gold, platinum and silver, carbide burrs are ideal while they last a very long time without chipping or breaking.

Steel, Carbon Steel & Metal
Surefire
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 probably be most suitable to specific materials, see the next point below to discover more regarding the different cuts.

What can You utilize Carbide Burs In?
Ideally carbide burrs are employed 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.

Only use a handpiece that runs true i.e with no wobble.

Who Uses Carbide Burs?
Carbide burrs are popular for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. And so are found in the aerospace, automotive, dental, metal sculpting, and metal smith industries to mention but a few.

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

Arch ball/pointed nose – engraving, texturing, increasing hole size
Ball – concave cuts, hollowing, shaping, carving. Useful 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 called 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 vast selection 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, use of hard-to-reach areas, and acute angles.
Rounded tree – concave cuts and rounding edges
