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 due, and tolerate
higher temperatures without warping when you apply friction. 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.

Carbide Bur Cutting Tools can be used on:

Aluminum
Brass
Bronze
Carbon fiber
Cast iron
Ceramics
Copper
Fiberglass
Gold
Hard rubber
Plastic
Platinum
Silver
Steel
Stone
Titanium
Wood
Zinc

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

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, 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. If you apply too much pressure to the
bur (burr), the edges may chip, resulting in premature dulling.

Choose Double Cut or Single Cut Carbide Bur?

Double Cut

Our double cut carbide burs allow for rapid stock removal in harder materials. The addition of the left hand flutes reduces the pulling action, allowing better operator control. Double cut reduces the size of the chips and can be used at slower than normal speeds.

Single Cut

Our single cut carbide burs are for general purpose and designed for cast iron, steel, some copper and brass, and other ferrous materials. Single cut will give good material removal and good workpiece finishes.

Non-Ferrous Aluminum Cut Carbide Burs

Use our aluminum cut carbide burs on non-ferrous materials such as aluminum, copper and magnesium.

Our USA made carbide burs are used on hard materials including steel, aluminum and cast iron, all types of stone, ceramic, porcelain, hard wood, acrylics, fibreglass and reinforced plastics. When using aluminum cut burs on soft metals such as gold, platinum and silver, our burs are perfect because they will last a long time with no breaking or chipping.
