Facts It Is Important To Be Aware Of Carbide Bur

Just what is a carbide bur employed for? Carbide Burs are used for cutting, shaping, grinding and also for the eliminating sharp edges, burrs and excess material (deburring).


For drilling holes or cutting an opening in metal a carbide drill or 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’d ideally utilize a Diamond Burr.

Carbide Burrs Can be utilized on Many Materials
Tungsten Carbide burrs can be utilized on many materials: metals including steel, aluminum and iron, various wood, acrylics, fibreglass and plastics. When used on soft metals for example gold, platinum and silver, carbide burrs are perfect as they can last a long time without 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
Zinc
Wood
Different cuts of carbide burrs is going to be ideal to particular materials, start to see the next point below to discover more about the different cuts.

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 such as a Dremel.

Always use a handpiece that runs true i.e without 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 so are utilized in the aerospace, automotive, dental, metal sculpting, and metal smith industries to call but a few.

Burs (burrs) come in a variety of shapes and sizes, because both versions can be used for 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 (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
