The Application of Different Shape of Tungsten Carbide Burrs

Tungsten 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) 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.
