Rounded tree – concave cuts and rounding edges 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. Cylindrical – contour finishing and right-angled corners Cylindrical end cut – contour finishingĬarbide Cylindrical no end cut – contour finishing Flame – channel work and shaping Useful for wood, stone, metal engraving.īall nose cone – rounding edges, surface finishing, tight spaces, and angles.Ĭarbide Ball nose cylinder- contour finishingīall nose tree (also known as tapered) – concave cuts and rounding edges Cone – rounding edges, surface finishing, tight spaces, hard to reach areas. Zinc Carbide Burs (burrs) come in a variety of shapes and sizes, each of which can be used for different purposes:Īrch ball/pointed nose – engraving, texturing, increasing hole size Ball – concave cuts, hollowing, shaping, carving.
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. This means they are ideal for multiple purposes due to the fact that they maintain sharper cutting edges for longer periods of time. 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.Ĭarbide 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. 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). Additionally, they are used for deburring, where burrs, excess materials, sharp edges, and weld beads are removed.

We manufacture a huge selection of carbide burs on 1/4″ shanks all made here in the USA.
