What is a carbide bur useful 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 dent in metal then this carbide drill or a carbide end mill, carbide slot drill or even a carbide router is required rather than carbide burr. For carving into stone you’ll ideally use a Diamond Burr.
Carbide Burrs May be used on Many Materials
Tungsten Carbide burrs works extremely well on many materials: metals including steel, aluminum and iron, various wood, acrylics, fibreglass and plastics. When suited for soft metals for example gold, platinum and silver, carbide burrs are ideal since they last a long time without having chipping or breaking.
Steel, Carbon Steel & Metal
Cast Iron
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 be most suitable to particular materials, understand the next point below to find out about the various cuts.
Exactly what do You Use 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 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 therefore are utilized in the aerospace, automotive, dental, metal sculpting, and metal smith industries to mention just a few.

Burs (burrs) appear in various size and shapes, as both versions can be used different purposes:
Arch ball/pointed nose – engraving, texturing, increasing hole size
Ball – concave cuts, hollowing, shaping, carving. Ideal 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, challenging 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, use of hard-to-reach areas, and acute angles.
Rounded tree – concave cuts and rounding edges
