What is a carbide bur used for? Carbide Burs are used for cutting, shaping, grinding and also for the removing sharp edges, burrs and excess material (deburring).
For drilling holes or cutting a dent in metal then a carbide drill or even a carbide end mill, carbide slot drill or even a carbide router is needed as opposed to a carbide burr. For carving into stone you’ll 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 cast iron, various wood, acrylics, fibreglass and plastics. When utilized on soft metals including gold, platinum and silver, carbide burrs are ideal as they lasts a long time without having chipping or breaking.
Steel, Carbon Steel & Stainless-steel
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 ideal to specific materials, begin to see the next point below to find out about different cuts.
What Do You utilize Carbide Burs In?
Ideally carbide burrs are widely-used in Air Tools i.e Die Grinders, Pneumatic rotary tools and high 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 wobble.
Who Uses Carbide Burs?
Carbide burrs are traditionally 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 found in the aerospace, automotive, dental, metal sculpting, and metal smith industries to mention just a few.

Burs (burrs) appear in a number of shapes and forms, because both versions can be used as 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 (also called 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, usage of hard-to-reach areas, and acute angles.
Rounded tree – concave cuts and rounding edges
