Carbide burs (burrs) are tools that are used for precision in cutting, grinding, and shaping the material with which they are being worked. Additionally, they are used for deburring, where burrs, excess materials, sharp edges, and weld beads are removed. Use carbide burs in industrial tools, such as air tools (e.g., die grinders), engravers, flexible shafts, and pendant drills, as well as for hobbies (e.g., Dremel tools). Their uses are varied and diverse, such as jewelry work, metalworking, welding, woodworking, and cover a range of industries, including aeronautics, aviation, automotive, dentistry, and metal and stone working.

Carbide burs (burrs) are generally composed of titanium or tungsten; diamond is the only material on the Mohs scale that is harder and also used for drill tips. This means they are ideal for multiple purposes due to the fact that they maintain sharper cutting edges for longer periods of time. Carbide burs (burrs) maintain their sharp edges 10 20 times longer than a stainless-steel bur (burr), depending on the frequency of use and the materials used with.

Uses for Carbide Bur Cutting Tools:

Carbon fiber
Cast iron
Hard rubber

Carbide Burs (burrs) come in a variety of shapes and sizes, each of which can be used for 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 known as 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 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

Carbide Burs (burrs) also come in a variety of ranges, each of which has a specific benefit in their use:

Alloy-specific – heads have varying shapes used with certain metal alloys – used in the
aerospace/aviation industry
Base metal range – used for deburring on softer metals
Bolt remover range – used for the removal of broken studs
Foundry metal range – used for deburring on harder metals, stone, etc.
Inox range – specifically used with stainless steel
Locksmith range – used by locksmiths
Long shank range – general-purpose; long shafts useful for deeper, hard-to-reach areas
Miniature range – miniature heads useful for engraving and fine detail work
New geometry range – used for all general metal removal
Steel range – heads have specialized fluting to cut stainless steel
Universal range – general-purpose, best on metals such as copper, iron, nickel, and steel

Carbide burs (burrs) require a bit of special care to keep them performing optimally. To preserve the life
of your carbide burs (burrs), ensure your handpiece does not wobble. The speed of your rotary tool
should not exceed 35,000 RPMs, and speed should be gradually increased. Please note, however,
that higher speeds will prevent flute clogging inside the bur (burr). If you apply too much pressure to the
bur (burr), the edges may chip, resulting in premature dulling.

carbide bur cut

Choose Double or Single Cut Carbide Bur?

Double Cut

Used on ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials such as stone, plastics, hard wood and ceramic. Double cut have more cutting edges and will remove material much faster. Double cut will leave a smoother finish than single cut due to producing smaller chips as they cut away the material. Use for medium-light stock removal, deburring, finishing and cleaning.
Designed for medium- light removal of material, deburring, fine finishing, cleaning, smooth finish, and creating small chips.

Single Cut

Usually used with stainless steel, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly with a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.
Designed for heavy removal of material, milling, deburring, cleaning, and creating long chips.

Aluminum Cut

Non-ferrous are exactly what you would expect them to be. Use our cutting tools on non-ferrous materials such as aluminum, copper and magnesium.

Our USA made tungsten carbide burrs can be used on most hard materials including steel, aluminum and cast iron, all types of stone, ceramic, porcelain, hard wood, acrylics, fibreglass and reinforced plastics. If you use our burs on soft metals such as gold, platinum and silver, carbide burrs are perfect as they will last for a long time with no breaking or chipping.

Different cuts of carbide burrs will be best suited for certain materials.
