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


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

Carbide Burrs Works extremely well on Many Materials
Tungsten Carbide burrs can be utilized on many materials: metals including steel, aluminum and iron, all types of wood, acrylics, fibreglass and plastics. When utilized on soft metals including gold, platinum and silver, carbide burrs are perfect as they lasts quite a while without any chipping or breaking.

Steel, Carbon Steel & Stainless-steel
Cast 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 suitable to specific materials, understand the next point below to find out about different cuts.

What Do 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 for instance a Dremel.

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

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

Burs (burrs) are available in various size and shapes, each of which bring 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 referred to 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, access to hard-to-reach areas, and acute angles.
Rounded tree – concave cuts and rounding edges
