The (SD) spherical cutting head (of the ball bur) is designed for deburring and finishing rounded openings and curvilinear surface profiles. They are used to remove excess material and sharp edges from machined components. Along with shaping bevels and other concave surfaces, the (SD) Ball Burs can also be used to enlarge holes. They attach to rotary power tools such as die grinders, high-speed engravers, and jewelers pendant drills. Their carbide head is hard and resists wear and heat.
Our Carbide (SD) Ball Burs are available in 1/4" and 1/8" shank diameters.
Basically a standard cutting tool, cuts are performed along the left-hand spiral. Double Cut Burs have multiple cutting edges which will remove material much faster. Double cut burs leave a smoother finish than standard cut burs because they produce smaller chips as they cut. The The Double cut profile provides better tool control in the removal of light-to-medium material, deburring, finishing and cleaning.

Bear/Shipyard Cut Burs (Heavy-Duty)
Our Bear/Shipyard cut burs can significantly reduce manufacturing production costs and remove more material per hour thanks to the overall design and tooth cut. Developed for heavy-duty applications with wider teeth to produce longer chips which disintegrate easier. The tooth profile reduces their propensity to accumulate chips; this is because of the depth and durability of the teeth. Perfect choice for use on mild steel, stainless steel, metal alloys and cast iron. Ideal for heavy duty applications such as shipbuilding, automotive, offshore drilling, and foundries.
